[英]AOP for annotation is not working in Spring Boot
我有myannotation,只要执行我的方法(具有myannotation),就应该调用AOP但它在我的spring boot控制器中不起作用,但是对具有其他注释的方法起作用,请帮助我了解发生了什么。
更新:MyAnnotation
@Retention(RUNTIME)
@Target({ METHOD, CONSTRUCTOR })
public @interface MyAnnotation {
}
@Aspect
@Component
public class AnnotationAspect {
private static final String POINTCUT_METHOD1 = "@annotation(com.somepackage.MyAnnotation)";
@Around(POINTCUT_METHOD1)
public Object weaveJoinPoint(ProceedingJoinPoint joinPoint) throws Throwable {
try {
System.out.println("Beforeee " + joinPoint);
joinPoint.proceed();
} finally {
System.out.println("Afterrr " + joinPoint);
}
return null;
}
}
方案1 :(工作中)
@Controller
@RequestMapping("user")
public class ArticleController {
@GetMapping("article/{id}")
@MyAnnotation // here it is
public ResponseEntity<String> getArticleById(@PathVariable("id") Integer id)
{
return new ResponseEntity<String>(dummyMethod(), HttpStatus.OK);
}
public String dummyMethod() {
System.out.println("Dummy method with MyAnnotation");
return "HelloWorld!";
}
}
日志:(工作中)
Beforeee execution(ResponseEntity com.mypackage.getArticleById(Integer))
Dummy method with MyAnnotation
Afterrr execution(ResponseEntity com.mypackage.getArticleById(Integer))
方案2 :(不起作用)
@Controller
@RequestMapping("user")
public class ArticleController {
@GetMapping("article/{id}")
public ResponseEntity<String> getArticleById(@PathVariable("id") Integer id)
{
return new ResponseEntity<String>(dummyMethod(), HttpStatus.OK);
}
@MyAnnotation //here it is
public String dummyMethod() {
System.out.println("Dummy method with MyAnnotation");
return "HelloWorld!";
}
}
日志:(不起作用)
Dummy method with MyAnnotation
方案3 :(无效)
@Service
public class ArticleService {
@MyAnnotation //here it is
public String dummyMethod() {
System.out.println("Dummy method with MyAnnotation");
return "HelloWorld!";
}
}
我可能无法正常工作,因为您从同一类调用了dummyMethod()。 尝试将dummyMethod()移至另一个服务类。 原因是同一类内的调用不会通过Spring代理进行。 对getArticleById()的调用已被代理,将由AOP处理,但dummyMethod()可能也是私有方法。
