相关疑难解决方法(0)

我想在Spring(3.2.3)@Controller中的每个方法之前运行一些代码.我有以下定义,但它不会运行.我怀疑切入点表达式是不正确的.

调度员servlet.xml中

<aop:aspectj-autoproxy/>
<bean class="com.example.web.controllers.ThingAspect"/>

cewcThingAspect

@Pointcut("execution(com.example.web.controllers.ThingController.*(..))")
public void thing() {
}

@Before("thing()")
public void doStuffBeforeThing(JoinPoint joinPoint) {
    // do stuff here
}

如何使用带注释的控制器实现AOP？

我已经搜索并找到了之前关于这个问题的两篇帖子,但似乎无法让解决方案起作用.

这就是我所拥有的:

派遣Servlet:

        <aop:include name="fooAspect" />

控制器:

@Controller
public class FooController {

    @RequestMapping(value="/index.htm", method=RequestMethod.GET)
    public String showIndex(Model model){
        return "index";
    }
}

方面:

@Aspect
public class FooAspect {

    @Pointcut("@target(org.springframework.stereotype.Controller)")
    public void controllerPointcutter() {}

    @Pointcut("execution(* *(..))")
    public void methodPointcutter() {}

    @Before("controllerPointcutter()")
    public void beforeMethodInController(JoinPoint jp){
        System.out.println("### before controller call...");
    }

    @AfterReturning("controllerPointcutter() && …
