Spring Boot AOP
提问by user1595702
I am having some issues trying to get my advice to execute. I tried several different pointcuts to no avail. The "@EnableAspectJProxy" seems to be working and detects my aspect. Any advice is appreciated.
我在尝试执行我的建议时遇到了一些问题。我尝试了几个不同的切入点，但无济于事。“@EnableAspectJProxy”似乎正在工作并检测到我的方面。任何建议表示赞赏。
I am using spring-boot-aop-starter.
我正在使用 spring-boot-aop-starter。
@Aspect
@Component
public class ExecutionTimeLogger {
private Logger logger;
public ExecutionTimeLogger() {
logger = LoggerFactory.getLogger(getClass());
logger.info("HEY");
}
@Pointcut("within(@org.springframework.stereotype.Controller *)")
public void controller() {}
@Pointcut("execution(* edu.x.y.z.server.web.controller.*.*(*))")
public void methodPointcut() {}
@Pointcut("within(@org.springframework.web.bind.annotation.RequestMapping *)")
public void requestMapping() {}
@Around("controller() && methodPointcut() && requestMapping()")
public Object profile(ProceedingJoinPoint pjp) throws Throwable {
StopWatch sw = new StopWatch();
String name = pjp.getSignature().getName();
try {
sw.start();
return pjp.proceed();
} finally {
sw.stop();
logger.info("STOPWATCH: " + sw.getTime() + " - " + name);
}
}
}
I am trying to match any method that is within my package and is annotated with the @RequestMapping annotation. I have tried the very generic match any and all methods without any luck too.
我正在尝试匹配我的包中的任何方法，并使用 @RequestMapping 注释进行注释。我也尝试过非常通用的 match any 和 all 方法，但没有任何运气。
Here is a sample of a method that the advice should be applied to:
以下是建议应用于的方法示例：
@RequestMapping(value = "/analysis", method = RequestMethod.GET)
@ApiOperation(value = "Get analyses available for the current user")
JsonModelAndView getAllAnalyses(HttpServletRequest request)

I managed to get this resolved. I ended up creating a small spring application to test the use case with the specific pointcuts to remove other potential barriers. I found that my pointcuts needed some adjusting.
我设法解决了这个问题。我最终创建了一个小型 spring 应用程序来测试具有特定切入点的用例，以消除其他潜在障碍。我发现我的切入点需要一些调整。
@Aspect
@Component
public class ExecutionTimeLogger {
private Logger logger;
public ExecutionTimeLogger() {
logger = LoggerFactory.getLogger(getClass());
logger.info("HEY");
}
@Pointcut("@annotation(org.springframework.web.bind.annotation.RequestMapping)")
public void requestMapping() {}
@Pointcut("execution(* edu.x.y.z.server.web.controller.*Controller.*(..))")
public void methodPointcut() {}
@Around("requestMapping() && methodPointcut()")
public Object profile(ProceedingJoinPoint pjp) throws Throwable {
StopWatch sw = new StopWatch();
String name = pjp.getSignature().getName();
try {
sw.start();
return pjp.proceed();
} finally {
sw.stop();
logger.info("STOPWATCH: " + sw.getTime() + " - " + name);
}
}
}
As you can see the big difference was the annotation pointcut.
正如您所看到的，最大的区别是注释切入点。

You might want to set proxyTargetClass=true (assuming your controllers do not have an interface). Use your own @EnableASpectJAutoProxyor set spring.aop.proxyTargetClass=true.
