springboot Aop 统一处理Web请求日志

Posted 2020-10-17 xmz_java

1.增加依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

2.编写切面类

@Aspect
@Component
public class WebLogAspect {}

注解 @Aspect 表明这是个切面类

3.定义切点

@Pointcut("execution(* com.example.manage.controller.*.*(..))")
    public void pointLog(){}

表明切入点为 com.example.manage.controller 路径下所有类 所有方法

4.定义切入的内容

@Before("pointLog()")
    public void dobefore(JoinPoint joinPoint){
        // 接收到请求，记录请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        
        logger.info("URL : "+request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        logger.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
    }

执行方法前先打印出请求信息

@AfterReturning(returning = "res", pointcut = "pointLog()")
    public void doAfterReturning(Object res) throws Throwable {
        // 处理完请求，返回内容
        logger.info("RESPONSE : " + res.toString());
    }

执行完毕后，打印返回内容

完毕！
