spring boot + Actuator 监控组件

spring boot Actuator 监控组件

Actuator对应用程序进行监视和管理,通过restful api请求来监管、审计、收集应用的运行情况,针对微服务而言它是必不可少的一个环节…

在pom.xml文件中 添加依赖:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>build-info</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

在配置文件中添加配置:

info:
  head: head
  body: body
management:
  endpoints:
    web:
      exposure:
        #加载所有的端点,默认只加载了info、health
        include: '*'
  endpoint:
    health:
      show-details: always
    #可以关闭指定的端点
    shutdown:
      enabled: false

启动后访问路径: http://localhost:8080/actuator

自定义健康端点

import org.springframework.boot.actuate.health.AbstractHealthIndicator;
import org.springframework.boot.actuate.health.Health;
import org.springframework.stereotype.Component;

@Component("my2")
public class MyAbstractHealthIndicator extends AbstractHealthIndicator {

    private static final String VERSION = "v1.0.0";

    @Override
    protected void doHealthCheck(Health.Builder builder) throws Exception {
        int code = check();
        if (code != 0) {
            builder.down().withDetail("code", code).withDetail("version", VERSION).build();
        }
        builder.withDetail("code", code)
                .withDetail("version", VERSION).up().build();
    }

    private int check() {
        return 0;
    }
}
