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接口。簡單的配置和使用如下：
1、引入依賴：
|
1
2
3
4
|
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> |
如果使用http調用的方式，還需要這個依賴：
|
1
2
3
4
|
<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端口（如果不指定，則使用和server相同的端口）；指定去掉某項的檢查（比如不監控health.mail）：
|
1
2
3
4
5
6
7
|
server: port: 8082 management: port: 54001 health: mail: enabled: false |
3、使用：
查看health指標：http://localhost:54001/health
|
1
|
{"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接口，然后實現其中的health()方法即可：
代碼：

@SpringBootApplication@EnableSchedulingpublic 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接口調用的時候，返回多一個屬性："mySpringBootApplication":{"status":"UP","hello":"world"} */ @Override public Health health() { return Health.up().withDetail("hello", "world").build(); } } |
/health 運行結果（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，可以直接給一個字符串，也可以從pom.xml配置中獲取
|

|
info: app: name: "@project.name@" #從pom.xml中獲取 description: "@project.description@" version: "@project.version@" spring-boot-version: "@project.parent.version@" |
/info的結果如下：
{"app":{"name":"my-spring-boot","description":"Test Project for Spring Boot","version":"1.0","spring-boot-version":"1.3.6.RELEASE"}}
