SpringBoot的生产特性SpringBoot Actuator

Java SpringBoot

1、在项目中引入SpringBoot Actuator依赖

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

2、日志打印显示暴露的端点

2019-12-07 16:59:00.362  INFO 17196 --- [  restartedMain] o.s.b.a.e.web.EndpointLinksResolver      : Exposing 2 endpoint(s) beneath base path '/actuator'

3、输入项目的主机IP和端口以及日志的路径进行访问

http://localhost:8080/actuator

http://localhost:8080/actuator/health

4、在运行日志中可以看到本次进程的PID

2019-12-08 10:53:37.638  INFO 14160 --- [  restartedMain] c.f.s.SpringBootExpandApplication        : Starting SpringBootExpandApplication on LAPTOP-CMGC7APE with PID 14160 (D:\Dome\SpringBootHD\SpringBootExpand\target\classes started by Fcant in D:\Dome\SpringBootHD)

5、按下Win+R打开运行，输入命令jconsole

6、查看Java进程的相关信息

7、在配置文件配置暴露更多的信息

management:
  endpoints:
    web:
      exposure:
        include: '*'

8、再次访问/actuator显示了更多的信息

日志中显示暴露了13个端点

2019-12-08 11:20:37.149  INFO 14160 --- [  restartedMain] o.s.b.a.e.web.EndpointLinksResolver      : Exposing 13 endpoint(s) beneath base path '/actuator'

再次访问URL

        "self": {
            "href": "http://localhost:8080/actuator",
            "templated": false

9、其他具体的使用如健康检查和Bean加载可以访问相应的路径

A.查看Bean的加载依赖-http://localhost:8080/actuator/beans
