Spring @Controller 和事务管理器 [英] Spring @Controller and Transactionmanager

问题描述

我有一个基本的 Spring Controller

I'm having a basic Spring Controller

package org.foo;

@Controller
public class HelloWorldController implements IHelloWorldController
{
   @RequestMapping(value = "/b/c/", method = RequestMethod.GET)
   public void doCriticalStuff(HttpServletRequest request, HttpServletResponse response){
      //...
   }
}

通过 curl -X GET http://myIP:myPort/b/c/ 测试哪个工作正常.

Tested via curl -X GET http://myIP:myPort/b/c/ Which works fine.

如果我通过

<bean id="txManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="*" />
    </tx:attributes>
</tx:advice>
<aop:config>
    <aop:pointcut id="helloWorldPC"
        expression="execution(* org.foo.IHelloWorldController.*(..)) &amp;&amp; !execution(* java.lang.Object.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="helloWorldPC" />
</aop:config>

映射不再起作用.我在客户端和服务器上收到 404 错误未输入方法.使用 doCriticalStuff 中的断点执行 JUnit 测试我可以看到 AopUtils.invokeJoinpointUsingReflection(Object, Method, Object[]) line: ... 因此使用了事务配置.

The mapping is not working any longer. I get a 404 Error on client side an on Server the Method is not entered. Doing a JUnit test with a breakpoint in doCriticalStuff I can see AopUtils.invokeJoinpointUsingReflection(Object, Method, Object[]) line: ... so the transaction config is used.

但是映射不再起作用.有任何想法吗?

But the mapping is not working any longer. Any ideas?

我使用的是 Spring 3.0.2.RELEASE

I'm using Spring 3.0.2.RELEASE

推荐答案

使用 动态代理，它阻止 Spring MVC 访问目标类上的 @RequestMapping 注释.您可以使用 <aop:config proxy-target-class="true"> 作为解决方法.

Transactional aspect is applied using dynamic proxy, and it prevents Spring MVC from accessing the @RequestMapping annotations on the target class. You may use <aop:config proxy-target-class="true"> as a workaround.

Spring 团队表示，出于效率原因，他们不会修复此行为(请参阅 评论 SPR-5084)

Spring team says that they wouldn't fix this behaviour for efficiency reasons (see comment on SPR-5084)
