Spring AOP 自定义注解获取http接口及WebService接口入参和出参

1.定义两个方法注解,分别标记要处理的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.定义Spring AOP切入点,两种接口注解切入点,注意 中间用||,网上也有说明使用or,试过之后发现or后面的切入点无效

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

3.环绕式加入切入点

@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)获取接口入参,postHandle(retVal)获取接口出参

 

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.切面类定义,注意需要添加@Component,否则将扫描不到切面类

@Aspect
@Component
public class WebRequestAroundAdvice {

}
