ssm整合步骤

1.配置applicationContext

用spring来管理mybaits的工厂类

    <!-- 数据库连接池 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="driverClass" value="com.mysql.jdbc.Driver" />        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/springmvc" />        <property name="user" value="root" />        <property name="password" value="123456" />    </bean>    <!-- 配置mybatis工厂 -->    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="configLocation" value="classpath:SqlMapConfig.xml"></property>        <property name="dataSource" ref="dataSource"></property>    </bean>    <!-- 自动扫描mapper之后生成实现类 -->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.wind.mapper"></property>    </bean>

然后把相应的mapper下的东西可以用mybatis逆向工程来生成

SqlMapConfig.xml中设置个别名 也就是在mapper中不需要写全名了，直接写类名

<configuration>    <!-- 别名 -->    <typeAliases>        <package name="com.wind.bean" />    </typeAliases></configuration>

mybatis的配置差不多完成了
接下来就是springmvc的配置了
首先要写一个springmvc.xml

    <!-- 注解扫描 -->    <context:component-scan base-package="com.wind"></context:component-scan>    <!-- 注解驱动 映射器 适配器 -->  <!-- 配置转换器 -->    <mvc:annotation-driven conversion-service="myconversion" />    <bean id="myconversion"        class="org.springframework.format.support.FormattingConversionServiceFactoryBean">        <property name="converters">            <list>                <bean class="com.wind.conversion.MyDateFormat"></bean>            </list>        </property>    </bean>    <!-- 视图解析器 -->    <bean        class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <!-- 前缀 后缀 -->        <property name="prefix" value="/WEB-INF/jsp/"></property>        <property name="suffix" value=".jsp"></property>    </bean>

然后在web.xml中配置spring 与SpringMVC的前端控制器 还有POST提交解决乱码的filter(过滤器)

    <!-- spring随项目启动 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- springmvc的前端控制器 -->    <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.xml</param-value>        </init-param>    </servlet>    <servlet-mapping>        <servlet-name>springmvc</servlet-name>        <url-pattern>*.action</url-pattern>    </servlet-mapping>    <!-- 解决POST提交的乱码问题 -->    <filter>        <filter-name>encoding</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>encoding</filter-name>        <url-pattern>*.action</url-pattern>    </filter-mapping>

接下来就是写controller层了
然后在controller的类中加入service的接口
在service层中加入Mapper的接口
