# 第一步 添加actuator依赖 #

1.**pom.xml** 如下：

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.0.3.RELEASE</version>
            <relativePath/> 
        </parent>
        <groupId>com.example</groupId>
        <artifactId>configuration</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <name>configuration</name>
        <description>Demo project for Spring Boot</description>
    
        <properties>
            <java.version>1.8</java.version>
        </properties>
    
        <dependencies>
    
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
    </project>

# 第二步 加入配置 #

1.**application.properties** 如下:

#web服务端端口
    server.port=6000
    
    #监控地址端口
    management.server.port=8000
    
    #springboot2.0之后，在Http环境下将默认的endpoint只设置为info和health，要想开启其他的监控功能，需要手动配置
    management.endpoints.web.exposure.include=*
    
    #请求连接前缀 默认是/actuator
    management.endpoints.web.base-path=/actuator
    
    #开启远程关闭服务
    management.endpoint.shutdown.enabled=true

# 第三步 启动验证 #

### 1.启动项目 ###

启动日志信息中包含如下信息：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JlbG9uZ2h1YW5nMTU3NDA1_size_16_color_FFFFFF_t_70]

从上图可以看出我们将要测试的映射连接地址

### 2.使用浏览器或者Postman ###

2.1.在地址栏输入 [http://127.0.0.1:8000/actuator/shutdown][http_127.0.0.1_8000_actuator_shutdown] ，如能正常返回 如下则成功访问

{
      "message": "Shutting down, bye..."
    }

2.2.查看后台日志打印结果

写在最后，如果项目部署在外网环境，请谨慎使用 ~ ~
