SSM(SpringMVC+Spring+Mybatis)
1.加jar包
用maven构建项目：
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.8.10</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.10</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.2.8.FINAL</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.40</version>
</dependency>

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-dbcp2</artifactId>
<version>2.1.1</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>

<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.5.10</version>
</dependency>

<dependency>

<artifactId>struts2-json-plugin</artifactId>
<version>2.5.10</version>
</dependency>

<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-spring-plugin</artifactId>
<version>2.5.10</version>
</dependency>

<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-convention-plugin</artifactId>
<version>2.5.10</version>
</dependency>

<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-all</artifactId>
<version>1.10.19</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>

<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.1</version>
<scope>provided</scope>
</dependency>

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
2.web.xml的配置文件
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContent.xml</param-value>
</context-param>（通过配置上下文参数指定Spring配置文件的位置）

<filter>
<filter-name>method</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter> （浏览器只能发送post/get请求，过滤器将浏览器发送过来的post转化成相应的delete/put请求）

<filter-mapping>
<filter-name>method</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>（/、/的区别在于：/*会覆盖默认设置）

<filter>
<filter-name>enc</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-mapping>
<filter-name>enc</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</filter>（字符集编码过滤器）

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>（监听器：服务器启动就初始化IOC容器）

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

<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>（前端控制器：如果这里的servlet-name叫dispatcher,那么springMVC的配置文件就一定要叫：dispatcher-servlet.xml）

3.Spring的配置文件 - applicationContext.xml
<context:component-scan base-package="com.qfedu.ssmybatis" />
<context:annotation-config />(扫描com.qfedu.ssmybatis路径下的注解)

<bean id="dataSource" destroy-method="close"
    class="org.apache.commons.dbcp2.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/dang?useUnicode=true&amp;characterEncode=utf8"/>
<property name="username" value="root"/>
<property name="password" value="123456"/>
</bean>（连接数据库,配置数据源）

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="typeAliasesPackage" value="com.qfedu.ssmybatis.entity" />
    <!-- <property name="typeHandlersPackage" value="com.qfedu.ssmybatis.typehandlers" /> -->
    <property name="mapperLocations" value="classpath*:com/qfedu/ssmybatis/mapper/*.xml" />
    <!-- <property name="configLocation" value="WEB-INF/mybatisconfig.xml" /> -->
</bean>

<bean id="sqlSessionTempLate" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg index="0" ref="sqlSessionFactory" />
</bean>(配置sessionFactory)

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>(配置事务管理器)

<tx:annotation-driven transaction-manager="transactionManager"/>(扫描注解驱动)

4.SpringMVC的配置文件 - dispacther-servlet

<mvc:default-servlet-handler/>(配置默认的servlethandler ,servlet在找页面时，走的是dispatcherServlet路线。找不到的时候会报404
加上这个默认的servlet时候，servlet在找不到的时候会去找静态的内容。
的DispatcherServlet拦截 .do这样的URL，就不存在访问不到静态资源的问题。如果你的DispatcherServlet拦截“/”，拦截了所有的请求，同时对.js,*.jpg的访问也就被拦截了。
目的：可以正常访问静态文件，不要找不到静态文件报404。)

<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>(配置视图解析器)

<mvc:annotation-driven>
    <mvc:message-converters>
         <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
         <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
         <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter" />
    </mvc:message-converters>
</mvc:annotation-driven>（配置数据转换器）
