SpringBoot服务添加自定义注解增加接口日志切面功能

• 1.日志切面注解定义

@Target(ElementType.METHOD) //注解放置的目标位置,METHOD是可注解在方法级别上
@Retention(RetentionPolicy.RUNTIME)  //注解在哪个阶段执行
@Documented
public @interface SysLog {
    String value() default "";
}

• 2.日志切面类

@Aspect
@Component
@Slf4j
public class AspectLog {

    ThreadLocal<Long> startTime = new ThreadLocal<Long>();

    @Pointcut("@annotation(com.jysp.core.annotation.SysLog)")
    public void logPointCut() {
    }

    @Before(value = "logPointCut()")
    public void methodBefore(JoinPoint joinPoint) {
        //开始时间
        startTime.set(System.currentTimeMillis());
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = requestAttributes.getRequest();
        //打印请求内容
        log.info("===============请求内容===============");
        log.info("请求地址:" + request.getRequestURL().toString());
        log.info("请求方式:" + request.getMethod());
        log.info("请求类方法:" + joinPoint.getSignature());
        String args = joinPoint.getArgs() != null ? Arrays.toString(joinPoint.getArgs()) : "";
        log.info("请求类方法参数:" + args);
        log.info("=======================================");
    }

    @AfterReturning(returning = "o", pointcut = "logPointCut()")
    public void methodAfterReturning(Object o) {
        //打印返回内容
        log.info("--------------返回内容----------------");
        String responseContent = o != null ? JSON.toJSONString(o) : "";
        log.info("Response内容:" + responseContent);
        //打印响应时间
        log.info("--------------响应时间----------------");
        log.info("请求处理时间为:" + (System.currentTimeMillis() - startTime.get()) + "毫秒");
        log.info("=======================================");
    }
}

• 3.接口方法上增加注解

　　@SysLog
　　@PostMapping("/test")
　　public ResponseBean<String> test(@RequestBody Test dto) {
　　}
