AOP 实现日志打印

自定义注解

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
public @interface Log {

    /**
     * 模块名称
     */
    String module() default "";

    /**
     * 具体操作
     */
    String desc() default "";

}

定义切面

@Aspect
@Component
@Slf4j
public class LogAspect {

    @Pointcut("@annotation(operationLog)")
    private void recordLog(Log operationLog) {
    }

    @Around("recordLog(operationLog)")
    public Object logAround(ProceedingJoinPoint pjp, Log operationLog) throws
            Throwable {
        String module = operationLog.module();
        String desc = operationLog.desc();
        long uid = System.nanoTime();
        String threadName = Thread.currentThread().getName();

        log.info("{} - 【{}】 模块: {}, 操作: {}, 请求参数: {}",
                threadName, uid, module, desc, Arrays.toString(pjp.getArgs()));
        Object ret = pjp.proceed();
        log.info("{} - 【{}】 返回值: {}", threadName, uid, ret);

        return ret;
    }

}

Controller 测试

@Log(module = "认证模块", desc = "用户登录")
@PostMapping("/login")
public String login(@RequestBody LoginDTO loginDTO, @RequestParam(value = "remember", required = false) boolean rememberMe) {
    return authService.login(loginDTO);
}

输出结果
