spring拆分配置文件详解

1.下面为spring-core.xml

<?xml version="1.0" encoding="UTF-8"?>
<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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.2.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
	  ">
	<!-- 导入database -->
	<context:property-placeholder location="classpath:database.properties"/>
	<!-- 配置基础数据源 -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${driver}"/>
		<property name="username" value="${user}"/>
		<property name="password" value="${password}"/>
		<property name="url" value="${url}"/>
	</bean>
	<!-- 配置SqlSessionFactoryBean -->
	<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 导入mybatis-config.xml -->
		<property name="configLocation" value="classpath:mybatis-config.xml" />
		<!-- 导入基础数据源 -->
		<property name="dataSource" ref="dataSource" />
		<!--配置mybatis 的mapper关联 -->
		<property name="mapperLocations">
			<list>
				<value>classpath:cn/zy/dao/*.xml</value>
			</list>
		</property>
	</bean>
	<!-- 配置事务管理器 -->
	<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<!-- 配置增强类 -->
	<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="get*" read-only="true" propagation="REQUIRES_NEW"/>
		</tx:attributes>
	</tx:advice>
	<!-- 切面aop -->
	<aop:config>
		<aop:pointcut expression="execution(* cn.zy.dao.*.*(..)))" id="pc"/>
		<aop:advisor advice-ref="txAdvice" pointcut-ref="pc"/>
	</aop:config>
</beans>

2.下面为spring-dao.xml

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	<!-- 配置mapper 接口所在的包 -->
	<property name="basePackage" value="cn.zy.dao" />
	<property name="sqlSessionFactoryBeanName" value="sessionFactory" />
</bean>

3.下面为spring-service.xml

<!-- 注解注入service -->
<context:component-scan base-package="cn.zy.service"/>

4.以下是spring-servlet.xml中的内容

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.2.xsd
	http://www.springframework.org/schema/mvc
	http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
	">
	<!-- 扫描类 -->
	<context:component-scan base-package="cn.zy.control" />
	<!-- 扫描mvc -->
	<!-- <mvc:annotation-driven /> -->
	<mvc:annotation-driven>
		<mvc:message-converters>
			<!-- 原生ajax 中文编码处理 -->
			<bean class="org.springframework.http.converter.StringHttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>
						<value>text/html;charset=utf-8</value>
					</list>
				</property>
			</bean>
			<!-- fastjson 中文编码处理 -->
			<bean
				class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
				<property name="supportedMediaTypes">

						<value>application/json;charset=utf-8</value>
					</list>
				</property>
			</bean>
		</mvc:message-converters>
	</mvc:annotation-driven>
	<mvc:resources location="/resoource/" mapping="/resoource/**" />
	<!-- 创建视图解析器 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>
	<mvc:interceptors>
		<mvc:interceptor>
			<mvc:mapping path="/**"/>
			<mvc:exclude-mapping path="/resoource/**"/>
			<mvc:exclude-mapping path="/WEB-INF/jsp/login.jsp"/>
			<mvc:exclude-mapping path="/user/login.html"/>
			<bean class="cn.zy.util.UserLoginInterceptor"></bean>
		</mvc:interceptor>
	</mvc:interceptors>
</beans>

下面为applicationContext.xml

<!--组合拆分文件-->
<import resource="spring-core.xml"/>
<import resource="spring-dao.xml"/>
<import resource="spring-service.xml"/>

下面为web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	</context-param>
	<!-- 配置spring 监听器，让spring容器之间可以互相访问 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 配置mvc 拦截 -->

		</init-param>
	</servlet>
	<servlet-mapping>
		<servlet-name>mvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

	<welcome-file-list>
		<welcome-file>/WEB-INF/jsp/login.jsp</welcome-file>
	</welcome-file-list>

	<!-- form 表单post 中文乱码 -->
	<filter>
