springboot统一处理日志

采用切面的方式：

@Aspect
@Component
public class WebLogAspect {

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

    @Pointcut("execution(public * com.fbc..controller.*.*(..))")//两个..代表所有子目录，最后括号里的两个..代表所有参数
    public void logPointCut() {
    }

    @Before("logPointCut()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到请求，记录请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        // 记录下请求内容
        logger.info("请求地址 : " + request.getRequestURL().toString());
        logger.info("HTTP METHOD : " + request.getMethod());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "."
                + joinPoint.getSignature().getName());
        logger.info("参数 : " + Arrays.toString(joinPoint.getArgs()));
//        loggger.info("参数 : " + joinPoint.getArgs());

    }

    @AfterReturning(returning = "ret", pointcut = "logPointCut()")// returning的值和doAfterReturning的参数名一致
    public void doAfterReturning(Object ret) throws Throwable {
        logger.info("返回值 : " + ret);
    }

    @Around("logPointCut()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object ob = pjp.proceed();// ob 为方法的返回值
        logger.info("耗时 : " + (System.currentTimeMillis() - startTime));
        return ob;
    }
}
