我的项目一共会分为4个模块：entity、dao、service和web

一、创建父模块

填写GroupId与ArtifactId

填写项目名称和项目保存路径

因为是父模块所以src包可以删除

二、创建entity子模块

右键项目选择Module

和父模块一样点击下一步

填写ArtifactId

点击Finish子模块创建完成

结构如下

dao、service的步骤和entity子模块步骤一样，创建完成后结构如下

 三、创建web子模块

点击Module

勾选上选择webapp点击下一步

填写ArtifactId点击下一步

点击下一步

点击finish多模块创建完成

多模块结构如下

可以看到idea创建时web模块的main包下的结构和其他模块不同，可以手动修改，修改完成后点击ok

正确的结构如下

至此，我们的多模块创建完成，接下来整合ssm

四、添加模块之间的相关依赖

这是preant模块的pom.xml文件如下

五、spring整合springMVC

创建springmvc.xml

代码如下

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

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

       xmlns:context="http://www.springframework.org/schema/context"

       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- springmvc 扫包范围 -->

    <context:component-scan base-package="com.chaoqi.controller"/>

    <!-- 开启springmvc注解 -->

    <mvc:annotation-driven/>

    <!-- 视图跳转类型 -->

    <bean

            class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/WEB-INF/jsp/"/>

        <property name="suffix" value=".jsp"/>

    </bean>

</beans>

编写测试类controller

package com.chaoqi.controller;

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

import org.springframework.stereotype.Controller;

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

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

import java.util.List;

@Controller

public class TestController {

    private static final String Hello = "hello";

    @RequestMapping("/test")

    public String test() {

        return Hello;

    }

}

创建jsp页面

配置web-xml文件

<?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"

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

         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

         version="2.5">

    <!-- 解决post乱码 -->

    <filter>

        <filter-name>CharacterEncodingFilter</filter-name>

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

        <init-param>

            <param-name>encoding</param-name>

            <param-value>UTF-8</param-value>

        </init-param>

        <!-- <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value>

            </init-param> -->

    </filter>

    <filter-mapping>

        <filter-name>CharacterEncodingFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <!-- springmvc的前端控制器 -->

    <servlet>

        <servlet-name>chaoqi-web</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" -->

        <init-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>classpath:spring/springmvc.xml</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>chaoqi-web</servlet-name>

        <url-pattern>/</url-pattern>

    </servlet-mapping>

</web-app>

接下来就是运行项目打，首先打包项目

配置完后点击OK

build完成后，结构如下

配置tomcat

点击运行

结果如下

六、spring整合mybatis

创建数据库    数据库采用的是mysql数据库

--学生登陆表

CREATE TABLE `user_login` (

  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键(自增长)',

  `user_name` varchar(30) DEFAULT NULL COMMENT '用户名',

    `pass_word` varchar(30) DEFAULT NULL COMMENT '密码',

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;

添加两条数据

insert into user_login (user_name,pass_word) VALUES ('猪点点','')

insert into user_login (user_name,pass_word) VALUES ('会飞的大象','')

创建实体类

创建UserLoginMapper 接口和xml

创建service接口和serviceImpl实现类

创建db.properties

jdbc.driver=com.mysql.jdbc.Driver

jdbc.host=localhost

jdbc.database=test

jdbc.userName=root

jdbc.passWord=123456

jdbc.initialSize=0

jdbc.maxActive=20

jdbc.maxIdle=20

jdbc.minIdle=1

jdbc.maxWait=1000

创建applicatiionController-service.xml和applicatiionController-dao.xml配置文件

@Controller

public class TestController {

    private static final String HELLO = "hello";

    @Autowired

    private UserLoginService userLoginService;

    @RequestMapping("/test")

    public String test() {

        return HELLO;

    }

    @ResponseBody

    @RequestMapping("/getUserLogin")

    public List<UserLogin> getViideType() {

        List<UserLogin> userLogin = userLoginService.getVideoInfo(null);

        for (UserLogin userLogins : userLogin) {

        }

        return userLogin;
