Shiro集成SSM基于URL权限管理(一)

学习了shiro之后，我们就可以说尝试把shiro加入ssm中，并做一套基于URL的权限管理。

其他的准备工作就不多说了，直接动手操作，看到效果再去理解。

表结构

执行如下，数据库名字可以自行修改，不过要和自己手动创建的数据库名字以及之后代码中的数据库名字保持一致。

 DROP DATABASE IF EXISTS shiro;

 CREATE DATABASE shiro DEFAULT CHARACTER SET utf8;

 USE shiro;

    

 drop table if exists user;

 drop table if exists role;

 drop table if exists permission;

 drop table if exists user_role;

 drop table if exists role_permission;

    

 create table user (

   id bigint auto_increment,

   name varchar(100),

   password varchar(100),

   salt varchar(100),

   constraint pk_users primary key(id)

 ) charset=utf8 ENGINE=InnoDB;

    

 create table role (

   id bigint auto_increment,

   name varchar(100),

   desc_ varchar(100),

   constraint pk_roles primary key(id)

 ) charset=utf8 ENGINE=InnoDB;

    

 create table permission (

   id bigint auto_increment,

   name varchar(100),

   desc_ varchar(100),

   url varchar(100), 

   constraint pk_permissions primary key(id)

 ) charset=utf8 ENGINE=InnoDB;

    

 create table user_role (

   id bigint auto_increment,

   uid bigint,

   rid bigint,

   constraint pk_users_roles primary key(id)

 ) charset=utf8 ENGINE=InnoDB;

    

 create table role_permission (

   id bigint auto_increment,

   rid bigint,

   pid bigint,

   constraint pk_roles_permissions primary key(id)

 ) charset=utf8 ENGINE=InnoDB;

表数据

 INSERT INTO `user_role` VALUES (43,2,2);

 INSERT INTO `user_role` VALUES (45,1,1);

和我们正常创建ssm项目，一样。

web.xml

web.xml做了如下几件事情

1. 指定spring的配置文件有两个

applicationContext.xml：用于链接数据库的

applicationContext-shiro.xml：用于配置shiro的。

2. 指定springmvc的配置文件

springMVC.xml

3. 使用shiro过滤器

<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

代码如下：

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

 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          xmlns="http://java.sun.com/xml/ns/javaee"

     </filter-mapping>

 </web-app>

applicationContext.xml

1.配置数据库的相关信息（这些配置根据自己的需要自行修改）
2. 扫描mybatis的mapper之类的

代码如下：

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

 </beans>

applicationContext-shiro.xml

提供shiro的相关配置，简单的说，就是把我们之前做练习的shiro.ini里的内容搬到这个xml文件里面来了，只是写法不同。

配合DatabaseRealm,做了 shiro教程中的shiro.ini 中做的事情
设置密码匹配器

</bean>

让DatabaseRealm使用这个密码匹配器

</bean>

代码如下：

springMVC.xml

1.springmvc的基本配置
2. 增加了对shiro的支持
这样可以在控制器Controller上，使用像@RequireRole 这样的注解，来表示某个方法必须有相关的角色才能访问
3. 指定了异常处理类DefaultExceptionHandler，这样当访问没有权限的资源的时候，就会跳到统一的页面去显示错误信息

代码如下：

PageController.java

因为使用 ssm，所以jsp通常都会放在WEB-INF/jsp 下面，而这个位置是无法通过浏览器直接访问的，所以就会专门做这么一个类，便于访问这些jsp。
比如要访问WEB-INF/jsp/index.jsp文件，那么就通过/index 这个路径来访问。
这个类还有两点需要注意：
1. /login 只支持get方式。 post方式是后续用来进行登录行为的，这里的get方式仅仅用于显示登录页面
2. 权限注解：
通过注解： @RequiresRoles("admin") 指明了访问 deleteProduct 需要角色"admin"
通过注解：@RequiresPermissions("deleteOrder") 指明了访问 deleteOrder 需要权限"deleteOrder"

我们在哪里需要使用权限，就在哪里加上对应注解，但是当我们的权限配置关系发生改变的时候，我们不得不修改代码，这在实际项目中是不可能的。为了解决这一问题我们引入了url配置权限。

代码如下：

 package com.how2java.controller;

 import org.apache.shiro.authz.annotation.RequiresPermissions;

 import org.apache.shiro.authz.annotation.RequiresRoles;

 import org.springframework.stereotype.Controller;

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

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

 //专门用于显示页面的控制器

 @Controller

 @RequestMapping("")

 public class PageController {

     @RequestMapping("index")

     public String index(){

         return "index";

     }

     @RequiresPermissions("deleteOrder")

     @RequestMapping("deleteOrder")

     public String deleteOrder(){

         return "deleteOrder";

     }

     @RequiresRoles("productManager")

     @RequestMapping("deleteProduct")

     public String deleteProduct(){

         return "deleteProduct";

     }

     @RequestMapping("listProduct")

     public String listProduct(){

         return "listProduct";

     }

     @RequestMapping(value="/login",method=RequestMethod.GET)

     public String login(){

         return "login";

     }

     @RequestMapping("unauthorized")

     public String noPerms(){

         return "unauthorized";

     }

 public class OverIsMergeablePlugin extends PluginAdapter {

     @Override

     public boolean validate(List<String> warnings) {

         return true;

     }

     @Override

     public boolean sqlMapGenerated(GeneratedXmlFile sqlMap, IntrospectedTable introspectedTable) {

         try {

             Field field = sqlMap.getClass().getDeclaredField("isMergeable");

             field.setAccessible(true);

             field.setBoolean(sqlMap, false);

         } catch (Exception e) {

运行 MybatisGenerator 以获取自动生成 Pojo、Example 和 Mapper

记得刷新一下项目。

         u.setSalt(salt);

         userService.add(u);

         return "redirect:listUser";

     }

 }

DatabaseRealm

代码如下:

 package com.how2java.realm;

 import java.util.Set;

 import org.apache.shiro.authc.AuthenticationException;

 import org.apache.shiro.authc.AuthenticationInfo;

 import org.apache.shiro.authc.AuthenticationToken;

 import org.apache.shiro.authc.SimpleAuthenticationInfo;

 import org.apache.shiro.authc.UsernamePasswordToken;

 import org.apache.shiro.authz.AuthorizationInfo;

 import org.apache.shiro.authz.SimpleAuthorizationInfo;

 import org.apache.shiro.codec.CodecException;

 import org.apache.shiro.crypto.UnknownAlgorithmException;

 import org.apache.shiro.crypto.hash.SimpleHash;

 import org.apache.shiro.realm.AuthorizingRealm;

 import org.apache.shiro.subject.PrincipalCollection;

 import org.apache.shiro.util.ByteSource;

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

 import com.how2java.pojo.User;

 import com.how2java.service.PermissionService;

 import com.how2java.service.RoleService;

 import com.how2java.service.UserService;

 public class DatabaseRealm extends AuthorizingRealm {

     @Autowired

     private UserService userService;

     @Autowired

     private RoleService roleService;

     @Autowired

     private PermissionService permissionService;

     @Override

     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

         //能进入到这里，表示账号已经通过验证了

         String userName =(String) principalCollection.getPrimaryPrincipal();

         //通过service获取角色和权限

         Set<String> permissions = permissionService.listPermissions(userName);

         Set<String> roles = roleService.listRoleNames(userName);

         //授权对象

         SimpleAuthorizationInfo s = new SimpleAuthorizationInfo();

         //把通过service获取到的角色和权限放进去

         s.setStringPermissions(permissions);

         s.setRoles(roles);

         return s;

     }

     @Override

     protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

         //获取账号密码

         UsernamePasswordToken t = (UsernamePasswordToken) token;

         String userName= token.getPrincipal().toString();

         //获取数据库中的密码

         User user =userService.getByName(userName);

         String passwordInDB = user.getPassword();

         String salt = user.getSalt();

         //认证信息里存放账号密码, getName() 是当前Realm的继承方法,通常返回当前类名 :databaseRealm

         //盐也放进去

         //这样通过applicationContext-shiro.xml里配置的 HashedCredentialsMatcher 进行自动校验

         SimpleAuthenticationInfo a = new SimpleAuthenticationInfo(userName,passwordInDB,ByteSource.Util.bytes(salt),getName());

         return a;

     }

 }

 DefaultExceptionHandler

 代码如下：

 package com.how2java.exception;

 import org.apache.shiro.authz.UnauthorizedException;

 import org.springframework.http.HttpStatus;

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

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

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

 import org.springframework.web.context.request.NativeWebRequest;

 import org.springframework.web.servlet.ModelAndView;

 @ControllerAdvice

 public class DefaultExceptionHandler {

     @ExceptionHandler({UnauthorizedException.class})

     @ResponseStatus(HttpStatus.UNAUTHORIZED)

     public ModelAndView processUnauthenticatedException(NativeWebRequest request, UnauthorizedException e) {

         ModelAndView mv = new ModelAndView();

         mv.addObject("ex", e);

         mv.setViewName("unauthorized");

         return mv;

     }

 }

DefaultExceptionHandler

 package com.how2java.exception;

 import org.apache.shiro.authz.UnauthorizedException;

 import org.springframework.http.HttpStatus;

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

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

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

 import org.springframework.web.context.request.NativeWebRequest;

 import org.springframework.web.servlet.ModelAndView;

 @ControllerAdvice

 public class DefaultExceptionHandler {

     @ExceptionHandler({UnauthorizedException.class})

     @ResponseStatus(HttpStatus.UNAUTHORIZED)

     public ModelAndView processUnauthenticatedException(NativeWebRequest request, UnauthorizedException e) {

         ModelAndView mv = new ModelAndView();

         mv.addObject("ex", e);

         mv.setViewName("unauthorized");

         return mv;

     }

 }

http://127.0.0.1:8080/shirossm/index

项目名不一致的话自行修改。

不过此时的权限还是通过注解@RequiresRoles、@RequiresPermissions实现，而非动态url.。之后会在此基础上实现动态url了。

基本代码都贴出来了。如有需要demo源码，请留言，互相交流学习乐意分享。
