spring-boot actuator（監控）配置和使用
阿新 • • 發佈：2018-12-25
在生產環境中，需要實時或定期監控服務的可用性。spring-boot 的actuator（監控）功能提供了很多監控所需的介面。簡單的配置和使用如下：
1、引入依賴：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>如果使用http呼叫的方式，還需要這個依賴：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>
2、配置：
application.yml中指定監控的HTTP埠（如果不指定，則使用和server相同的埠）；指定去掉某項的檢查（比如不監控health.mail）：
server:
port: 8082
management:
port: 54001
health:
mail:
enabled: false3、使用：
檢視health指標：http://localhost:54001/health{"status":"UP","diskSpace":{"status":"UP","total":120031539200,"free":33554337792,"threshold":10485760},"db":{"status":"UP","dataSource1":{"status":"UP","database":"MySQL","hello":1},"dataSource2":{"status":"UP","database":"MySQL","hello":1}}}
4、自定義指標：
4.1 /health：在某個類中implements HealthIndicator介面，然後實現其中的health()方法即可：
程式碼：
@SpringBootApplication @EnableScheduling public class MySpringBootApplication implements HealthIndicator{ private static Logger logger = LoggerFactory.getLogger(MySpringBootApplication.class); public static void main(String[] args) { SpringApplication.run(MySpringBootApplication.class, args); logger.info("My Spring Boot Application Started"); } /** * 在/health介面呼叫的時候，返回多一個屬性："mySpringBootApplication":{"status":"UP","hello":"world"} */ @Override public Health health() { return Health.up().withDetail("hello", "world").build(); } }
/health 執行結果（注意第二個指標）：
{"status":"UP","mySpringBootApplication":{"status":"UP","hello":"world"},"diskSpace":{"status":"UP","total":120031539200,"free":33554337792,"threshold":10485760},"db":{"status":"UP","dataSource1":{"status":"UP","database":"MySQL","hello":1},"dataSource2":{"status":"UP","database":"MySQL","hello":1}}}
4.2 /info：配置如下，可以直接給一個字串，也可以從pom.xml配置中獲取
info:
app:
name: "@[email protected]" #從pom.xml中獲取
description: "@[email protected]"
version: "@[email protected]"
spring-boot-version: "@[email protected]"{"app":{"name":"my-spring-boot","description":"Test Project for Spring Boot","version":"1.0","spring-boot-version":"1.3.6.RELEASE"}}
