Spring AOP 自定義注解獲取http接口及WebService接口入參和出參

1.定義兩個方法注解，分別標記要處理的http接口及Webservice接口：

http接口注解

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

WebService接口注解

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

2.定義Spring AOP切入點，兩種接口注解切入點，注意 中間用||，網上也有說明使用or，試過之后發現or后面的切入點無效

@Pointcut("@annotation(ms.platform.base.interfaces.AnnotationForIntfMark) || @annotation(ms.platform.base.interfaces.AnnotationForWsMark)")
	public void pointcut() {
	}

3.環繞式加入切入點

@Around("pointcut()")
	public void handle(ProceedingJoinPoint joinPoint) throws Throwable {
		StringBuffer sb = new StringBuffer();
		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)獲取接口入參，postHandle(retVal)獲取接口出參

 

private String 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();
		boolean isIntf = false;
		StringBuffer sb = new StringBuffer();
		for (int i = 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 (int j = 0; j < args.length; j++) {
				sb.append(JsonUtil.bean2json(args[j]));
			}
		}
		return sb.toString();
	}

 

 

 

private String postHandle(Object retVal) {
		return JsonUtil.bean2json(retVal);
	}

 

5.切面類定義，注意需要添加@Component，否則將掃描不到切面類

@Aspect
@Component
public class WebRequestAroundAdvice {

}
