springAOP拦截并打印controller层请求日志---注解方式实现

@Component
@Aspect
public class RequestLog {

public static final Logger LOG = LoggerFactory.getLogger(RequestLog.class);

/**
* Define a pointcut
*/
//    @Pointcut("execution(* com.wqxia.*.*(..))")

}

/**

*/
@AfterThrowing(throwing = "ex", pointcut = "controllerLog()")

}

/**

*/
protected String getMethodDescription(JoinPoint joinPoint) throws Exception {
String targetName = joinPoint.getTarget().getClass().getName();
String methodName = joinPoint.getSignature().getName();
Object[] arguments = joinPoint.getArgs();

Method[] methods = targetClass.getMethods();

String description = "";
for (Method method : methods) {
if(method.getName().equals(methodName)) {
Class<?>[] clazzs = method.getParameterTypes();
if(clazzs.length == arguments.length) {
description = method.getAnnotation(SystemLog.class).description();
break;
}
}
}
return description;
}
}

注解：

/**
* System log annotation for controller or service
* Created by wenqiangxia on 9:10 2017/11/2
*/
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemLog {

String description() default "";
}

注解加在controller层方法上即可
