Spring @Transactional 适用于 Controller 但 Service 无效
Spring @Transactional works on Controller but Service has no effect
这是我的web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/app-root.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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
这是我的springmvc-servlet.xml
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
<context:component-scan base-package="com.***.***">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
</context:component-scan>
这是我的应用-root.xml
<import resource="classpath:spring/app-dao.xml"/>
<import resource="classpath:spring/shiro.xml"/>
<import resource="classpath:spring/app-timer.xml"/>
<import resource="classpath:spring/app-context.xml"/>
这是我的应用-context.xml
<context:component-scan base-package="com.xinshen.meeting">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
这是我的应用-datasource.xml
<bean id="adminTxManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<tx:annotation-driven transaction-manager="adminTxManager"/>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:spring/mybatis-config.xml"/>
<!--扫描entity包,使用别名-->
<property name="typeAliasesPackage" value="com.xinshen.meeting.model"/>
<property name="mapperLocations" value="classpath*:mappers/*.xml"/>
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageHelper">
<property name="properties">
<value>
dialect=mysql
</value>
</property>
</bean>
</array>
</property>
</bean>
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.***.***.dao"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean>
当我将 @Transactional 添加到 Controller 时,事务有效但服务无效!
下图是@Transactional on Service
enter image description here
下图是控制器上的@Transactional
enter image description here
实在是摸不着头脑,谢谢帮忙!
我认为您必须使用配置启用事务 在配置中添加此注释 @EnableTransactionManagement class
为配置创建 class:
@Configuration
@ComponentScan(basePackages = { "Your services package or base package" })
@EnableTransactionManagement
public class MyConfig {
}
如果您的服务没有实现接口,您需要在标签 tx:annotation-driven 中设置 proxy-target-class="true"。
您还应该在服务 class 上或直接在 spring bean 调用的函数上添加 @Transactional。
