关于ssm工程的配置文件配置方法

spring配置，分为三个（applicationContext-dao，applicationContext-service，applicationContext-transaction）

1. applicationContext-dao:主要配置关于dao层的相关配置

            <!-- 配置读取db.properties文件 -->
		<context:property-placeholder location="classpath:db.properties"/>
		
		<!-- 配置数据源 -->
		<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
			<!-- 驱动 -->
			<property name="driverClassName" value="${jdbc.driver}"></property>
			<!-- url -->
			<property name="url" value="${jdbc.url}"></property>
			<!-- username -->
			<property name="username" value="${jdbc.username}"></property>
			<!-- password -->
			<property name="password" value="${jdbc.password}"></property>
		</bean>
		
		<!-- 配置mybatis的工厂 -->
		 <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
			<property name="dataSource" ref="dataSource"></property>
			<!-- 自动扫描mapping配置文件  -->
			<!-- <property name="mapperLocations" value="classpath:com/myforum/mapper/*.xml"></property> -->
			<property name="configLocation" value="classpath:SqlMapConfig.xml"></property>
			 
		</bean>
                
		<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 
			<property name="basePackage" value="com.myforum.mapper"></property>	
			<property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"></property>	
		</bean>

2.applicationContext-service:主要配置Service层的相关配置

<!-- 配置扫描@service -->
<context:component-scan base-package="com.myforum.service"></context:component-scan>

3.applicationContext-transaction：配置事务的管理

<!-- 事务管理器 -->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!-- 数据源 -->
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	
	<!-- 通知 -->
	<tx:advice id="txadvice" transaction-manager="transactionManager">
		<!-- 传播行为 -->
		<tx:attributes>
			<tx:method name="save*" propagation="REQUIRED"/>
			<tx:method name="insert*" propagation="REQUIRED"/>
			<tx:method name="add*" propagation="REQUIRED"/>
			<tx:method name="update*" propagation="REQUIRED"/>
			<tx:method name="create*" propagation="REQUIRED"/>
			<tx:method name="delete*" propagation="REQUIRED"/>
			<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
			<tx:method name="select*" propagation="SUPPORTS" read-only="true"/>
			<tx:method name="get*" propagation="SUPPORTS" read-only="true"/>
		</tx:attributes>
	</tx:advice>
	
	<!-- 切面 -->
	<aop:config>
		<aop:advisor advice-ref="txadvice" pointcut="execution(* com.myforum.service.*.*(..))"/>
	</aop:config>

SpringMvc的配置：

<!-- 配置扫描包 -->
	<context:component-scan base-package="com.myforum.controller"></context:component-scan>
	<!-- 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>
	<mvc:default-servlet-handler/>
	<mvc:annotation-driven>
	     <mvc:message-converters>
	            <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
	            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
	   </mvc:message-converters>
	</mvc:annotation-driven>

Mybatis的配置文件可不用配置（不可缺少该文件）

Web.xml的配置：

<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  
  <welcome-file-list>
  	<welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
    
  <!-- 加载spring容器（配置文件） -->
  	<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>
 
  <servlet>
  	<servlet-name>springMvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<!-- 如果没有配置，则去/WEB-INF/+<servlet-name>+servlet.xml找  -->
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:springMvc.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 拦截器 -->
  <servlet-mapping>
  	<servlet-name>springMvc</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>

<!--   <servlet-mapping>
  	<servlet-name>springMvc</servlet-name>
  	<url-pattern>index.jsp</url-pattern>
  </servlet-mapping> -->
    <!-- 设置全局编码 -->
  <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>
    
</web-app>

到此，基本的配置就完成了，其他的可以到需要在进行配置.
