SSM（Spring+Spring MVC+MyBatis）框架整合搭建详细步骤 SSM三大框架整合详细教程（Spring+SpringMVC+MyBatis）

SSM详细整合教程

因为XML+注解方式实现更加方便，所以我门选用它

一、整合思路

1. 先将搭建Web开发的总体三层目录结构
2. 编写Spring框架
3. 编写SpringMvc框架
4. Spring与Mvc整合
5. 编写Mybatis框架
6. Spring与Mbatis整合

二、整合步骤

0. 前期准备引入Jar包与Web目录创建

1. Spring框架编写

1.1 创建Application配置文件

• 因为Controller后续会交给SpringMvc管理，所以我们这的配置文件不需要管理Controller注解

• 关于为什么要向这样做，我们最后做解释:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx
        https://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">
<!-- 注解扫描，忽略Controller   -->
    <context:component-scan base-package="com.atjianyi">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

2. SpringMvc框架编写

2.1 创建Springmvc-config文件

- 同样在resources目录下

- 编写Springmvc配置文件

关于SpringMvc，我们只需要管理controller就可以了，所以配置注解包扫描时候，只需要关注Controller注即可。

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spri ng-context.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 配置注解扫描   -->
    <context:component-scan base-package="com.atjianyi">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

<!--  配置视图解析器  -->
    <bean id="is" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
<!--  静态资源过滤  -->
    <mvc:resources mapping="/js/**" location="/js/"/>
    <mvc:resources mapping="/css/**" location="/css/"/>
    <mvc:resources mapping="/img/**" location="/img/"/>
<!-- 支持Springmvc框架   -->
    <mvc:annotation-driven/>
</beans>

2. 2 配置前端控制器

<!-- Spring Mvc start前端控制器 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc-config.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
<filter>
  <filter-name>charsetFilter</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>
</filter>
  <filter-mapping>
    <filter-name>charsetFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
<!-- SpringMvc end -->

3. Spring与SpringMvc整合

3.1 Spring与SpringMvc整合说明

当我们的服务器启动时候，我们需要服务器去帮助我们创建IOC容器，也就是需要去加载我们的applicationContext配置文件。

3.2 Spring与SpringMvc整合思路

• ServletContext域对象
  • 服务器启动时候，就创建，服务器关闭，就执行销毁
• 一类监听器
  • 能监听ServletContext域对象的创建和销毁
• ContextLoadListen.对象

3.3 在webXML中注册监听并且去加载Spring配置文件

<!-- Spring -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
<!-- Spring End -->

默认他会去WEB-INF目录下找applicationContext.xml文件，但是我们的配置文件同一在resources下管理，所以我们使用context-param去更改。

4. Mybatis框架编写

直接跳过，看5.因为我们Spring与Mybatis整合，Mybatis将其中的SqlSeesionFactory对象，连接池对象等。同一交给Spring去管理就行，省去了我们手动编写环境标签的步骤…

5. Spring与Mybatis框架整合

5. 1. 创建Mybatis-config的配置文件。

5.1.1 编写mybatis-config配置文件配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <typeAliases>
        <package name="com.atjianyi.domain"/>
    </typeAliases>
    <!--与Spring整合，我们无需去编写环境，甚至将mapper都交给了Spring-->
</configuration>    

5.2 applciationContext.xml文件新增配置

<!--Mybatis-->
<!--  配置连接池  -->
<!-- 我们目前使用的druid数据库连接池，此处可以根据不同数据库连接池而定   -->
<bean id="ds" class="com.alibaba.druid.pool.DruidDataSourceFactory" factory-method="createDataSource">
    <constructor-arg name="properties">
        <props>
            <prop key="url">jdbc:mysql://localhost:3306/ssmbuild</prop>
            <prop key="driverClassName">com.mysql.jdbc.Driver</prop>
            <prop key="username">root</prop>
            <prop key="password">root</prop>
        </props>
    </constructor-arg>
</bean>
<!--  配置SqlSession工厂  -->
   <bean class="org.mybatis.spring.SqlSessionFactoryBean">
       <property name="dataSource" ref="ds"/>
   </bean>
<!--  配置包扫描  -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.atjianyi.dao"/>
</bean>

三、整合事务控制
