1 問題描述

在最近的一個專案中，採用springMVC、mybatis，發現一個很惱人的問題：事務管理不起作用！！網上查閱了大量的資料，嘗試了各種解決辦法，亦未能解決問題！

applicationContext.xml配置：

<context:annotation-config />
<!-- 引入jdbc屬性配置檔案 -->
<context:property-placeholder location="classpath:jdbc.properties" />	
<!-- 資料來源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
	<property name="driverClassName" value="${jdbc.driverClassName}"></property>
	<property name="url" value="${jdbc.url}"></property>
	<property name="username" value="${jdbc.username}"></property>
	<property name="password" value="${jdbc.password}"></property>
</bean> 
<bean id="ftpConfig" class="com.wtas.utils.CustomizedPropertyConfig">   
	<property name="location" value="classpath:ftp.properties" />
</bean>

<!-- 配置mybatis用到的sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	<property name="configLocation" value="classpath:mybatisConfig.xml" />
	<property name="dataSource" ref="dataSource" />
	<property name="typeAliasesPackage" value="com.wtas.study.domain,com.wtas.studygroup.domain,com.wtas.sys.domain,com.wtas.test.domain" />
	<property name="mapperLocations" value="classpath*:com/wtas/**/*Mapper.xml" />
</bean>
<!-- 根據對映檔案動態生成dao的實現 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	<property name="basePackage" value="com.wtas" />
	<property name="annotationClass" value="org.springframework.stereotype.Repository" />
</bean>
<!-- 事務控制 -->
<bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
	<property name="dataSource" ref="dataSource"></property>
</bean>
<tx:advice id="userTxAdvice" transaction-manager="transactionManager">
	<tx:attributes>
		<tx:method name="remove*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" no-rollback-for="java.lang.RuntimeException" />
		<tx:method name="delete*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" no-rollback-for="java.lang.RuntimeException" />

		<tx:method name="query*" propagation="SUPPORTS" read-only="true" />
		<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
		<tx:method name="page*" propagation="SUPPORTS" read-only="true" />
	</tx:attributes>
</tx:advice>
<tx:annotation-driven transaction-manager="transactionManager"/>
	<!-- execution(public * com.wtas.*.service.*.*(..)) OR   execution(public * com.wtas.*.*.*.service.*.*(..))-->
<aop:config>
	<aop:pointcut id="pc" expression="execution(public * com.wtas.*.service.*.*(..))" />
	<aop:advisor pointcut-ref="pc" advice-ref="userTxAdvice" />
</aop:config>

springMVC.xml配置：

<!-- 這裡註冊轉換器 -->
<mvc:annotation-driven conversion-service="conversionService" />
        <context:component-scan base-package="com.wtas"></context:component-scan>
<mvc:default-servlet-handler />

<!-- 註冊ConversionService -->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
	<!-- 轉換器 -->
	<property name="converters">
		<list>
			<bean class="com.wtas.converter.StringToDateConverter">
				<constructor-arg value="yyyy-MM-dd" />
			</bean>
		</list>
	</property>
</bean>

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
	<property name="messageConverters">
		<list>
        		<bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter" />
			<bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter" />
			<bean class="org.springframework.http.converter.StringHttpMessageConverter" />
			<bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
		</list>
	</property>
</bean>

<!-- 檢視解釋類 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/WEB-INF/jsps/" />
	<property name="suffix" value=".jsp" />
	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
</bean>

2 排查過程

具體原理，請參考：深入分析Spring與Spring MVC容器。

3 解決問題

applicationContext.xml中新增：

<context:component-scan base-package="com.wtas">
	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> 
</context:component-scan>
複製程式碼

springMVC.xml中修改：

<!-- 掃描所有的controller 但是不掃描service-->  
<context:component-scan base-package="com.wtas">  
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />  
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" />  
</context:component-scan>
