SSM框架项目搭建

一、创建一个web项目

二、在lib文件夹下导入所需要的包

三、配置web.xml文件

1.配置前端控制器-DispatherServlet类

<servlet>
       <servlet-name>springmvc</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispathcherServlet</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>
           

2.配置监听器，初始化spring容器

<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>
           

3.解决乱码文件，设置过滤器

<filter>
	<filter-name>encodingFilter</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>encodingFilter</filter-name>
	<url-pattern>/*</url-pattern>	
</filter-mapping>
           

四、在src下创建applicationContext.xml文件进行配置

1.开启包扫描

<context:component-scan base-package="包名全路径 "></context:component-scan>
           

2.注解方式注入DI

<context:annotation-config></context:annotation-config>
           

3.配置注解方式AOP

<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
           

4.整合Mybatis

配置数据源

<bean id="dataSource"class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
		<property name="jdbcUrl" value="jdbc:mysql:///easymall"></property>
		<property name="user" value="root"></property>
		<property name="password" value="root"></property>
</bean>
           

配置Mybatis

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="configLocation" value="classpath:/sqlMapConfig.xml"></property>
		<property name="mapperLocations" value="classpath:/cn/tedu/mapper/*.xml"></property>
</bean>
           

MapperBean扫描器，负责为MapperBean生成实现类

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="cn.tedu.mapper"></property>
</bean>
           

五、在src下创建springmvc.xml文件

1.开启包扫描

<context:component-scan base-package="cn.tedu.controller"></context:component-scan>
           

2.开启注解方式的mvc配置

<mvc:annotation-driven></mvc:annotation-driven>
           

3.配置视图解析器

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/"></property>	
		<property name="suffix" value=".jsp"></property>	
</bean>
           

4.配置拦截器

<mvc:interceptors>
		<bean class="cn.tedu.interceptor.AutologinInterceptor"></bean>
</mvc:interceptors>
           

六、在src下创建sqlConfigMap.xml文件

基本配置完成，开始实现逻辑代码
