# Spring Boot 使用Metrics监控 #

1.  导入pom依赖

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

1.  配置项中启用 metrics

management.endpoints.web.exposure.include=*

1.  需要监控调用次数的Controller配置如下：

@GetMapping("/dic")
        @Timed(value = "all.people", longTask = true)
        public String list() throws JsonProcessingException {
            return objectMapper.writeValueAsString(dictDao.list());
        }

1.  查看方式：  
    [http://127.0.0.1:8080/actuator/metrics/all.people][http_127.0.0.1_8080_actuator_metrics_all.people]
2.  [Spring Boot官网配置][Spring Boot]

## Spring Boot Metrics中查看版本等信息 ##

1.  [配置项中启用][Link 1]：

management.endpoints.web.exposure.include=*

1.  配置项中以info开头的配置，都会在info中显示
2.  info中显示git信息  
    
    
     *  在classpath中添加git.properties 配置文件

git.branch=master
    git.commit.id=sdxe2jdd
    git.commit.time=2018-03-25

1.  查看info信息  
    [http://127.0.0.1:8080/actuator/info][http_127.0.0.1_8080_actuator_info]

{
      "version": "1.0.0",
