Spring AOP custom annotations Get HTTP interface and WebService interface entry and exit parameters

The following methods can be obtained during the implementation of the annotation method:--for example

  HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()). Getrequest ();

1. Define two method annotations to mark the HTTP interface and WebService interface to be processed, respectively:

HTTP interface Annotations

12345

@Retention(RetentionPolicy.RUNTIME)@Target({ ElementType.TYPE, ElementType.METHOD })public@interfaceAnnotationForIntfMark {    String value();}

WebService interface Annotations

12345

@Retention(RetentionPolicy.RUNTIME)@Target({ ElementType.TYPE, ElementType.METHOD })public@interfaceAnnotationForWsMark {    String value();}

2. Define spring AOP pointcuts, two interface annotation pointcuts, note the Intermediate | |, the Internet also indicates the use or, after trying to find that the pointcut after or is invalid

123	@Pointcut("@annotation(ms.platform.base.interfaces.AnnotationForIntfMark) || @annotation(ms.platform.base.interfaces.AnnotationForWsMark)")    publicvoidpointcut() {    }

3. Wrap-Around Join entry point

12345678910

@Around("pointcut()")    publicvoidhandle(ProceedingJoinPoint joinPoint) throwsThrowable {        StringBuffer sb = newStringBuffer();        String reqParam = preHandle(joinPoint);        sb.append("Input Param:【").append(reqParam).append("】").append("\n");        Object retVal = joinPoint.proceed();        String respParam = postHandle(retVal);        sb.append("Output Param:【").append(respParam).append("】").append("\n");        MSLog.error(sb.toString());    }

4.preHandle (joinpoint) Get interface entry parameter, Posthandle (retVal) get interface out parameter

privateString preHandle(ProceedingJoinPoint joinPoint) {        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())                .getRequest();        Signature signature = joinPoint.getSignature();        MethodSignature methodSignature = (MethodSignature) signature;        Method targetMethod = methodSignature.getMethod();        Annotation[] annotations = targetMethod.getAnnotations();        booleanisIntf = false;        StringBuffer sb = newStringBuffer();        for(inti = 0; i < annotations.length; i++) {            if(annotations[i].annotationType().equals(AnnotationForIntfMark.class)) {                sb.append(request.getAttribute("jsonContent"));                isIntf = true;                break;            }        }        if(!isIntf) {            Object[] args = joinPoint.getArgs();            for(intj = 0; j < args.length; j++) {                sb.append(JsonUtil.bean2json(args[j]));            }        }        returnsb.toString();    }

123	privateString postHandle(Object retVal) {        returnJsonUtil.bean2json(retVal);    }

5. Slice class definition, note the need to add @Component, otherwise you will not scan the slice class
