对狂神的shiro的学习总结

1.shiro的10分钟快速开始

导入依赖

新建一个普通的maven项目,然后new一个hello-shiro(moudle)作为第一个测试项目

具体框架如下:

导入对应的依赖在pom.xml文件里

<dependencies>

        <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-core -->

        <dependency>

            <groupId>org.apache.shiro</groupId>

            <artifactId>shiro-core</artifactId>

            <version>1.7.1</version>

        </dependency>

        <!-- configure logging -->

        <dependency>

            <groupId>org.slf4j</groupId>

            <artifactId>jcl-over-slf4j</artifactId>

            <version>1.7.21</version>

        </dependency>

        <dependency>

            <groupId>org.slf4j</groupId>

            <artifactId>slf4j-log4j12</artifactId>

            <version>1.7.21</version>

        </dependency>

        <dependency>

            <groupId>log4j</groupId>

            <artifactId>log4j</artifactId>

            <version>1.2.17</version>

        </dependency>

    </dependencies>

配置文件

在官方的github目录下下载zip或者直接copy代码

shiro的github请点击这

在resources目录下新建一个log4j.properties和shiro.ini文件

如果idea创建失败ini文件或者识别ini失败可以看IDEA中怎么创建ini文件

log4j.properties具体代码如下:

log4j.rootLogger=INFO, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n

# General Apache libraries

log4j.logger.org.apache=WARN

# Spring

log4j.logger.org.springframework=WARN

# Default Shiro logging

log4j.logger.org.apache.shiro=INFO

# Disable verbose logging

log4j.logger.org.apache.shiro.util.ThreadContext=WARN

log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN

shiro.ini的具体代码如下:

[users]

# user 'root' with password 'secret' and the 'admin' role

root = secret, admin

# user 'guest' with the password 'guest' and the 'guest' role

guest = guest, guest

# user 'presidentskroob' with password '12345' ("That's the same combination on

# my luggage!!!" ;)), and role 'president'

presidentskroob = 12345, president

# user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'

darkhelmet = ludicrousspeed, darklord, schwartz

# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'

lonestarr = vespa, goodguy, schwartz

# -----------------------------------------------------------------------------

# Roles with assigned permissions

#

# Each line conforms to the format defined in the

# org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc

# -----------------------------------------------------------------------------

[roles]

# 'admin' role has all permissions, indicated by the wildcard '*'

admin = *

# The 'schwartz' role can do anything (*) with any lightsaber:

schwartz = lightsaber:*

# The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with

# license plate 'eagle5' (instance specific id)

goodguy = winnebago:drive:eagle5

在java目录导入Quickstart.java,具体代码如下:

import org.apache.shiro.SecurityUtils;

import org.apache.shiro.authc.*;

import org.apache.shiro.config.IniSecurityManagerFactory;

import org.apache.shiro.mgt.SecurityManager;

import org.apache.shiro.session.Session;

import org.apache.shiro.subject.Subject;

import org.apache.shiro.util.Factory;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

/**

 * Simple Quickstart application showing how to use Shiro's API.

 *

 * @since 0.9 RC2

 */

public class Quickstart {

    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);

    public static void main(String[] args) {

        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");

        SecurityManager securityManager = factory.getInstance();

        SecurityUtils.setSecurityManager(securityManager);

        // Now that a simple Shiro environment is set up, let's see what you can do:

        // get the currently executing user:

        //获取当前的用户对象

        Subject currentUser = SecurityUtils.getSubject();

        // Do some stuff with a Session (no need for a web or EJB container!!!)

        //通过当前用户拿到session

        Session session = currentUser.getSession();

        session.setAttribute("someKey", "aValue");

        String value = (String) session.getAttribute("someKey");

        if (value.equals("aValue")) {

            log.info("Retrieved the correct value! [" + value + "]");

        }

        //判断当前用户是否被认证

        //Token:没有获取,直接设置令牌

        if (!currentUser.isAuthenticated()) {

            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");

            token.setRememberMe(true);//设置记住我

            try {

                currentUser.login(token);//执行登录操作

            } catch (UnknownAccountException uae) {

                log.info("There is no user with username of " + token.getPrincipal());

            } catch (IncorrectCredentialsException ice) {

                log.info("Password for account " + token.getPrincipal() + " was incorrect!");

            } catch (LockedAccountException lae) {

                log.info("The account for username " + token.getPrincipal() + " is locked.  " +

                        "Please contact your administrator to unlock it.");

            }

            // ... catch more exceptions here (maybe custom ones specific to your application?

            catch (AuthenticationException ae) {

                //unexpected condition?  error?

            }

        }

        //say who they are:

        //print their identifying principal (in this case, a username):

        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //test a role:

        if (currentUser.hasRole("schwartz")) {

            log.info("May the Schwartz be with you!");

        } else {

            log.info("Hello, mere mortal.");

        }

        //粗粒度

        //test a typed permission (not instance-level)

        if (currentUser.isPermitted("lightsaber:wield")) {

            log.info("You may use a lightsaber ring.  Use it wisely.");

        } else {

            log.info("Sorry, lightsaber rings are for schwartz masters only.");

        }

        //细粒度

        //a (very powerful) Instance Level permission:

        if (currentUser.isPermitted("winnebago:drive:eagle5")) {

            log.info("You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'.  " +

                    "Here are the keys - have fun!");

        } else {

            log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");

        }

        //注销

        //all done - log out!

        currentUser.logout();

        //结束

        System.exit(0);

    }

}

HelloWorld

开启项目检查

看到能打印出这行信息,说明快如入门成功

2.springboot整合shiro环境搭建

新建一个moudle叫shiro-springboot

勾选spring web依赖即可

在pom.xml中导入thymeleaf依赖

<!--        thymeleaf模板-->

        <dependency>

            <groupId>org.thymeleaf</groupId>

            <artifactId>thymeleaf-spring5</artifactId>

        </dependency>

        <dependency>

            <groupId>org.thymeleaf.extras</groupId>

            <artifactId>thymeleaf-extras-java8time</artifactId>

        </dependency>

新建一个controller编写一个MyController测试,代码如下:

package cn.dzp.controller;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

public class MyController {

    @RequestMapping({"/index","/"})

    public String toIndex(Model model){

        model.addAttribute("msg","hello,shiro");

        return "index";

    }

}

在templates下新建一个index.html,导入thymeleaf约束,这样可以编写thymeleaf提示

xmlns:th="http://www.themeleaf.org"

index.html完整代码如下:

<!DOCTYPE html>

<html lang="en" xmlns:th="http://www.themeleaf.org">

<head>

    <meta charset="UTF-8">

    <title>首页</title>

</head>

<body>

<h1>首页</h1>

<p  th:text="${msg}"></p>

</body>

</html>

运行项目检查

可以看到可以跑通!

shiro的三大对象:

Subject:用户
SecurityManager:管理所有用户
Realm:连接数据

pom.xml导入依赖:

<!--shiro整合包-->

        <dependency>

            <groupId>org.apache.shiro</groupId>

            <artifactId>shiro-spring</artifactId>

            <version>1.7.1</version>

        </dependency>

创建一个config包编写ShiroConfig配置类

代码如下:

package cn.dzp.config;

import org.apache.shiro.spring.web.ShiroFilterFactoryBean;

import org.apache.shiro.web.mgt.DefaultWebSecurityManager;

import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

@Configuration

public class ShiroConfig {

//    ShiroFilterFactoryBean:第三步

    @Bean

    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){

        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();

//        设置安全管理器

        bean.setSecurityManager(defaultWebSecurityManager);

        return bean;

    }

//    DefaultWebSecurityManager:第二步

    @Bean(name = "securityManager")

    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){

        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();

//        关联UserRealm

        securityManager.setRealm(userRealm);

        return securityManager;

    }

//    Realm:创建realm对象,需要自定义:第一步,从后往前配置

    @Bean

    public UserRealm userRealm(){

        return new UserRealm();

    }

}

因为配置涉及到userRealm,这个需要自己自定义,所以在config包下再写一个UserRealm类

代码如下:

package cn.dzp.config;

import org.apache.shiro.authc.AuthenticationException;

import org.apache.shiro.authc.AuthenticationInfo;

import org.apache.shiro.authc.AuthenticationToken;

import org.apache.shiro.authz.AuthorizationInfo;

import org.apache.shiro.realm.AuthorizingRealm;

import org.apache.shiro.subject.PrincipalCollection;

//自定义的UserRealm

public class UserRealm extends AuthorizingRealm {

//    授权

    @Override

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

        System.out.println("执行了授权的=>doGetAuthorizationInfo");

        return null;

    }

//认证

    @Override

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        System.out.println("执行了认证的=>doGetAuthenticationInfo");

        return null;

    }

}

在templates建一个user夹放关于用户的页面:add.html;update:html

回到MyController

添加两个页面跳转的方法

@RequestMapping("/user/add")

    public String add(){

        return "user/add";

    }

@RequestMapping("/user/update")

    public String update(){

        return "user/update";

    }

回到主页index.html

再次重启项目检查

可以实现跳转add和update页面

到此环境搭建完成!

3.shiro实现登陆拦截

在ShiroConfig添加shiro的内置过滤器

//        添加shiro的内置过滤器

        /*

        * anon:无需认证都可访问

        * authc: 必须认证了才能访问

        * user:必须拥有 记住我 才能用

        * perms:拥有对某个资源的权限才能访问

        * role:拥有某个角色权限才能访问*/

        LinkedHashMap<String, String> filterMap = new LinkedHashMap<>();

        filterMap.put("/user/add","authc");

        filterMap.put("/user/update","authc");

        //filterMap.put("/user/*","authc");拦截所有user下的请求

        bean.setFilterChainDefinitionMap(filterMap);

再次运行项目点击add,发现失败,此时拦截已经成功了

因为它跳转的url是login页面,所以还得重写login页面

代码如下:

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>用户登录</title>

</head>

<body>

<h1>登录</h1>

<form action="/toLogin" method="post">

<p>用户名: <input type="text" name="username"></p>

<p>密码: <input type="password" name="password"></p>

<p><input type="submit"></p>

</form>

</body>

</html>

MyController添加方法

@RequestMapping("/toLogin")

    public String toLogin(){

        return "login";

    }

配置登录页面

点击add或者update已经跳转到了登录页面,说明已经拦截成功!

4.shiro实现用户认证

在MyController添加login方法:代码如下

 @RequestMapping("/login")

    public String login(String username,String password,Model model){

//        获取当前的用户

        Subject subject = SecurityUtils.getSubject();

//        封装用户的登录数据

        UsernamePasswordToken token = new UsernamePasswordToken(username, password);

        try {

            subject.login(token);//执行登录的方法,如果没有异常就说明ok了

            return "index";

        }catch (UnknownAccountException e){//用户名不存在

            model.addAttribute("msg","用户名错误");

            return "login";

        }catch (IncorrectCredentialsException e){//密码不存在

            model.addAttribute("msg","密码错误");

            return "login";

        }

    }

在login.html写入信息msg

启动项目随便登录测试一下

在UserRealm代码下修改认证代码:

//认证

@Override

protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

System.out.println("执行了认证的=>doGetAuthenticationInfo");

// 用户名,密码到数据库中取

String name="root";

String password="123456";

UsernamePasswordToken userToken = (UsernamePasswordToken) token;

if (!userToken.getUsername().equals(name)){

return null;//抛出异常:UnknownAccountException

}

// 密码认证:shiro做

return new SimpleAuthenticationInfo("",password,"");

}

重启项目查看,登录写的数据

可以看到登陆成功

5.shiro整合mybatis

在pom.xml导入对应的依赖

<!--        整合mybatis-->

        <dependency>

            <groupId>mysql</groupId>

            <artifactId>mysql-connector-java</artifactId>

        </dependency>

        <dependency>

            <groupId>log4j</groupId>

            <artifactId>log4j</artifactId>

            <version>1.2.17</version>

        </dependency>

        <dependency>

            <groupId>com.alibaba</groupId>

            <artifactId>druid</artifactId>

            <version>1.2.6</version>

        </dependency>

        <dependency>

            <groupId>org.mybatis.spring.boot</groupId>

            <artifactId>mybatis-spring-boot-starter</artifactId>

            <version>2.1.4</version>

        </dependency>

在resource目录下新建application.yaml配置文件

spring:

  datasource:

    username: root

    password: 123456

    url: jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf-8

    driver-class-name: com.mysql.cj.jdbc.Driver

    #    使用德鲁伊的数据源

    type: com.alibaba.druid.pool.DruidDataSource

    #Spring Boot 默认是不注入这些属性值的,需要自己绑定

    #druid 数据源专有配置

    initialSize: 5

    minIdle: 5

    maxActive: 20

    maxWait: 60000

    timeBetweenEvictionRunsMillis: 60000

    minEvictableIdleTimeMillis: 300000

    validationQuery: SELECT 1 FROM DUAL

    testWhileIdle: true

    testOnBorrow: false

    testOnReturn: false

    poolPreparedStatements: true

    #配置监控统计拦截的filters

    # stat:监控统计

    # log4j:日志记录(需要导入log4j依赖)

    # wall:防御sql注入

    filters: stat,wall,log4j

    maxPoolPreparedStatementPerConnectionSize: 20

    useGlobalDataSourceStat: true

    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

新建数据库连接绑定mybatis的数据库

application.properties文件里配置mybatis的相关设置

由于配置文件里多了别名的扫描和mapper的文件,所以要完整架构,新建一个pojo实体类和mapper的包,如下

pojo实体类为了方便代码简洁,我使用了lombok,在pom导入对应依赖即可

<dependency>

            <groupId>org.projectlombok</groupId>

            <artifactId>lombok</artifactId>

        </dependency>

实体类如下:

package cn.dzp.pojo;

import lombok.AllArgsConstructor;

import lombok.Data;

import lombok.NoArgsConstructor;

@Data

@AllArgsConstructor

@NoArgsConstructor

public class User {

    private int id;

    private String name;

    private String pwd;

}

编写mapper

在编写UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE mapper

        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="cn.dzp.mapper.UserMapper">

    <select id="queryUserByName" parameterType="String" resultType="user">

        select * from user where name=#{name}

    </select>

</mapper>

在新建service写一个UserService接口和它的实现类

UserMapperImpl实现类代码:

package cn.dzp.mapper;

import cn.dzp.pojo.User;

import cn.dzp.service.UserService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

@Service

public class UserMapperImpl implements UserService {

    @Autowired

    UserMapper userMapper;

    @Override

    public User queryUserByName(String name) {

        return userMapper.queryUserByName(name);

    }

}

在测试类测试代码

可以看到查询成功

这样就可以去改Realm的代码,开始的用户名和密码都是手写伪造的

UserRealm代码修改如下:

package cn.dzp.config;

import cn.dzp.pojo.User;

import cn.dzp.service.UserService;

import org.apache.shiro.authc.*;

import org.apache.shiro.authz.AuthorizationInfo;

import org.apache.shiro.realm.AuthorizingRealm;

import org.apache.shiro.subject.PrincipalCollection;

import org.springframework.beans.factory.annotation.Autowired;

//自定义的UserRealm

public class UserRealm extends AuthorizingRealm {

    @Autowired

    UserService userService;

//    授权

    @Override

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

        System.out.println("执行了授权的=>doGetAuthorizationInfo");

        return null;

    }

//认证

    @Override

    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

        System.out.println("执行了认证的=>doGetAuthenticationInfo");

//        用户名,密码到数据库中取

//        链接真实的数据库

        UsernamePasswordToken userToken = (UsernamePasswordToken) token;

        User user = userService.queryUserByName(userToken.getUsername());

        if (user==null){//没有这个人

            return null;//UnknownAccoutException

        }

//        密码认证:shiro做

//         密码可以加密:md5,md5盐值加密

        return new SimpleAuthenticationInfo("",user.getPwd(),"");

    }

}

现在的话登录用户就是数据库中的,启动项目测试

可以看到登录成功

6.shiro实现请求授权

在ShiroConfig添加部分代码,如图:

登录用户点击添加的请求,显示未授权401的错误

正常情况下,授权会跳转到未授权的页面,所以才MyController写一个跳转到未授权的页面方法

@ResponseBody

    @RequestMapping("/noauth")

    public String unauthorized(){

        return "无法访问此页面";

    }

ShiroConfig类修改一下:

重启项目测试,发现已经可以跳转到我们设置的未授权的页面了

怎样添加add页面的授权呢,在UserRealm修改下代码,因为ShiroConfig设定了add页面需要权限,所以要在UserRealm添加权限

但是所有登录的用户都有此权限,所以我打算把数据库的表新增一个权限的字段,添加下权限

记得改下User实体类

UserRealm类

ShiroConfig里添加对update的过滤

开启项目测试:

登录有add权限的账号dzp

点击add,成功跳转

登录有update权限的账号root

点击update,成功跳转

7.shiro整合thymeleaf

导入对应的依赖

<!--        shiro整合thymeleaf-->

        <dependency>

            <groupId>com.github.theborakompanioni</groupId>

            <artifactId>thymeleaf-extras-shiro</artifactId>

            <version>2.0.0</version>

ShiroConfig类添加方法

// 整合ShiroDialect:用来整合shiro thymeleaf

@Bean

public ShiroDialect getShiroDialect(){

return new ShiroDialect();

}



        </dependency>

在index.html添加约束

xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro"

运行项目测试

没有权限不会显示add和update的页面

为了让登录后不在显示登录按钮,需要在UserRealm里添加代码

然后在前端判断它从而决定显不显示登录按钮,

index.html:

<!DOCTYPE html>

<html lang="en" xmlns:th="http://www.themeleaf.org"

        xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">

<head>

    <meta charset="UTF-8">

    <title>首页</title>

</head>

<body>

<h1>首页</h1>

<p  th:text="${msg}"></p>

<div shiro:hasPermission="user:add">

    <a th:href="@{/user/add}">添加</a>

</div>

<div shiro:hasPermission="user:update">

    <a th:href="@{/user/update}">更新</a>

</div>

<br>

<div th:if="${session.loginUser==null}"><a th:href="@{/toLogin}">登录</a></div>

<div><a th:href="@{/logout}">注销</a></div>

</body>

</html>

运行项目检查,登录后登录按钮消失
