• 用途

  用于记录spring boot的请求和响应日志； aop实现；

• 依赖

1. lombok -如果没有，可以自已创建log对象

2. Slf4j -

3. jackson

4. apache common

• 实现

package xxx.xxx.xxx;import com.fasterxml.jackson.databind.ObjectMapper;import lombok.extern.slf4j.Slf4j;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.*;import org.springframework.aop.aspectj.MethodInvocationProceedingJoinPoint;import org.springframework.stereotype.Component;import org.springframework.web.context.request.RequestAttributes;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import javax.servlet.http.HttpServletRequest;/** * 用于记录web请求/响应日志 */@Component@Aspect@Slf4jpublic class WebLogAspect {    /**     * 切面, xxx.xxx.xxx.web.ctl是Controller包名     */    @Pointcut("execution(* xxx.xxx.xxx.web.ctl..*.*(..))")    private void parameterPointCut() {    }    /**     * 方法执行前，记录请求     * @param joinPoint     */    @Before("parameterPointCut()")    public void requestLog(JoinPoint joinPoint){        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();//这个RequestContextHolder是Springmvc提供来获得请求的东西        HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();        String queryStr = request.getQueryString();        if(StringUtils.isNotEmpty(queryStr)){            log.info("请求地址: [{}] {}",  request.getMethod(), request.getRequestURI());        }else{            log.info("请求地址: [{}] {}?{} ", request.getMethod(), request.getRequestURI(), queryStr);        }        printRequestArgs(joinPoint);    }    private void printRequestArgs(JoinPoint joinPoint){        log.info("请求方法: {}", joinPoint.toString());        Object[] reqArgs = joinPoint.getArgs();        if(null == reqArgs){            return;        }        int c = 0;        ObjectMapper mapper = new ObjectMapper();        for(Object arg: reqArgs){            try{                log.info("请求入参[{}]: {}", c, mapper.writeValueAsString(arg));            }catch (Exception ex){                log.error("请求入参转换异常", ex);            }            c++;        }    }    /**     * 方法执行后,记录响应     * @param joinPoint     * @param ret 方法执行结果注入对象     * @return     */    @AfterReturning(returning = "ret",pointcut = "parameterPointCut()")    public Object responeLog(JoinPoint joinPoint, Object ret){        try {            ObjectMapper mapper = new ObjectMapper();            log.info("响应出参: {}", mapper.writeValueAsString(ret));        } catch (Throwable ex) {            log.error("响应异常", ex);        }        return ret;    }}
