详解Spring Boot中使用AOP统一处理Web请求日志

时间:2022-11-18 10:10:55

在spring boot中,简单几步,使用spring AOP实现一个拦截器:

1、引入依赖

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-aop</artifactId>
 </dependency>

 2、创建拦截器类(在该类中,定义了拦截规则:拦截com.xjj.web.controller包下面的所有类中,有@RequestMapping注解的方法。):

3、测试

浏览器中输入:http://localhost:8082/api/admin/login

测试结果:

?

2016-07-26 11:58:12,057:INFO http-nio-8082-exec-1 (ControllerInterceptor.java:58) - 请求开始,方法:login
2016-07-26 11:58:12,061:INFO http-nio-8082-exec-1 (ControllerInterceptor.java:103) - login请求结束,耗时:8ms

2016-07-26 11:58:12,061:INFO http-nio-8082-exec-1 (ControllerInterceptor.java:103) - login请求结束,耗时:8ms

证明拦截器已经生效。
