springboot2

Collect and monitor the general performance metrics exposed by the SpringBoot 2.0 actuator.

Pre-monitoring operations

If you want to monitor information in 'SpringBoot' with this monitoring type, you need to integrate your SpringBoot application and enable the SpringBoot Actuator.

1、Add POM .XML dependencies:

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

2. Modify the YML configuration exposure metric interface:

management:
  endpoints:
    web:
      exposure:
        include: '*'
    enabled-by-default: on

Note: If your project also introduces authentication related dependencies, such as springboot security, the interfaces exposed by SpringBoot Actor may be intercepted. In this case, you need to manually release these interfaces. Taking springboot security as an example, you should add the following code to the Security Configuration class:

public class SecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception{
        httpSecurity
                // Configure the interfaces to be released -----------------------------------
                .antMatchers("/actuator/**").permitAll()
                .antMatchers("/metrics/**").permitAll()
                .antMatchers("/trace").permitAll()
                .antMatchers("/heapdump").permitAll()
                // 。。。
                // For other interfaces, please refer to: https://blog.csdn.net/JHIII/article/details/126601858 -----------------------------------
    }
}
