在生產(chǎn)環(huán)境中，需要實(shí)時(shí)或定期監(jiān)控服務(wù)的可用性。spring-boot 的actuator（監(jiān)控）功能提供了很多監(jiān)控所需的接口。簡(jiǎn)單的配置和使用如下：

創(chuàng)新互聯(lián)公司自2013年起，先為梁溪等服務(wù)建站，梁溪等地企業(yè)，進(jìn)行企業(yè)商務(wù)咨詢(xún)服務(wù)。為梁溪企業(yè)網(wǎng)站制作PC+手機(jī)+微官網(wǎng)三網(wǎng)同步一站式服務(wù)解決您的所有建站問(wèn)題。

1、引入依賴(lài)：

 
  org.springframework.boot 
  spring-boot-starter-actuator 
 

如果使用http調(diào)用的方式，還需要這個(gè)依賴(lài)：

 
  org.springframework.boot 
  spring-boot-starter-web 
 

2、配置：

application.yml中指定監(jiān)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(xiàng)的檢查（比如不監(jiān)控health.mail）：

server: 
 port: 8082 
management: 
 port: 54001 
 health: 
  mail: 
   enabled: false 

3、使用：

查看health指標(biāo)：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(biāo)：

4.1 /health：在某個(gè)類(lèi)中implements HealthIndicator接口，然后實(shí)現(xiàn)其中的health()方法即可：

代碼：

@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接口調(diào)用的時(shí)候，返回多一個(gè)屬性："mySpringBootApplication":{"status":"UP","hello":"world"} 
   */ 
  @Override 
  public Health health() { 
    return Health.up().withDetail("hello", "world").build(); 
  } 
} 

/health 運(yùn)行結(jié)果（注意第二個(gè)指標(biāo)）：

{"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(gè)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(jié)果如下：

{"app":{"name":"my-spring-boot","description":"Test Project for Spring Boot","version":"1.0","spring-boot-version":"1.3.6.RELEASE"}}
