AOP统一处理web请求日志-优快云博客

本文介绍如何在Spring Boot应用中使用AOP（面向切面编程）实现Web请求日志记录，包括请求URL、方法、IP、参数等，并演示了处理完请求返回内容的方法。

1、引入依赖

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

2、建立filter package
创建WebLogAspect类

/**
 * 描述：     打印请求和响应信息
 */
@Aspect
@Component
public class WebLogAspect {

    private final Logger log = LoggerFactory.getLogger(WebLogAspect.class);

    @Pointcut("execution(public * com.imooc.mall.controller.*.*(..)))")
    public void webLog() {

    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) {
        //分析并打印请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder
                .getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        log.info("request url:" + request.getRequestURL().toString());
        log.info("request method:" + request.getMethod());
        log.info("IP:" + request.getRemoteUser());
        log.info("class_method:" + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        log.info("args : " + Arrays.toString(joinPoint.getArgs()));
    }

    @AfterReturning(returning = "res", pointcut = "webLog()")
    public void doAfterReturning(Object res) throws JsonProcessingException {
        //处理完请求返回类容
        log.info("return response : " + new ObjectMapper().writeValueAsString(res));
    }
}
