Spring 之Aop实现日志记录

Aop实现见代码，简单demo实现

 package com.idcos.automate.config;

 @Aspect//切面注解
 @Component//@Component泛指组件，当组件不好归类的时候，我们可以使用这个注解进行标注。
 public class LoggerConfig {

     @Autowired
     private DcosLogDAO dcosLogDAO;

     private final org.slf4j.Logger log = LoggerFactory.getLogger(this.getClass());

     //定义切点，监听所有的web下的controller
     @Pointcut("execution(public * com.idcos.automate.web..*.*(..))")
     public void webLog() {
     }

     //抛出切点连接中的异常信息
     @AfterThrowing(pointcut = "webLog()", throwing = "e")
     public void logAfterThrowing(JoinPoint joinPoint, Throwable e) {
         log.error("Exception in {}.{}.() cause = {}", joinPoint.getSignature().getDeclaringType(), joinPoint.getSignature().getName(), e.getCause() != null ? e.getCause() : null);
     }

     /**

         long start = System.currentTimeMillis();
         //JoinPoint、ProceedingJoinPoint提供访问当前被通知方法的目标对象、代理对象、方法参数等数据，其中ProceedingJoinPoint提供访问当前被通知方法的目标对象
         // 在环绕Around时使用：

         long end = System.currentTimeMillis();//测试方法执行后的时间是多少
         float time =  BigDecimal.valueOf(end-start).divide(BigDecimal.valueOf()).setScale(, BigDecimal.ROUND_HALF_UP).floatValue();

         ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
         HttpServletRequest request = attributes.getRequest();

         // 记录下请求内容
         log.info("URL : " + request.getRequestURL().toString());//请求的url
         log.info("HTTP_METHOD : " + request.getMethod());//请求的方法
         log.info("IP : " + request.getRemoteAddr());//请求方的ip
         log.info("CLASS_METHOD : " + proceedingJoinPoint.getSignature().getDeclaringTypeName() + "." + proceedingJoinPoint.getSignature().getName());
         log.info("ARGS : " + Arrays.toString(proceedingJoinPoint.getArgs()));//请求的参数

         DcosLogDO dcosLogDO = new DcosLogDO();

         dcosLogDO.setClassName(request.getClass().getName());
         dcosLogDO.setMethodName(request.getMethod());
         dcosLogDO.setUrl(request.getRemoteAddr()+request.getRequestURL());
         dcosLogDO.setTime(Float.toString(time));
         dcosLogDAO.saveAndFlush(dcosLogDO);
     }
