创建 Spring Boot Admin Client
创建一个工程名为 hello-spring-cloud-admin-client 的项目，pom.xml 文件如下：
<?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>com.ycq</groupId> <artifactId>hello-spring-cloud-dependencies</artifactId> <version>1.0.0-SNAPSHOT</version> <relativePath>../hello-spring-cloud-dependencies/pom.xml</relativePath> </parent> <artifactId>hello-spring-cloud-admin-client</artifactId> <packaging>jar</packaging> <name>hello-spring-cloud-admin-client</name> <dependencies> <!-- Spring Boot Begin --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.jolokia</groupId> <artifactId>jolokia-core</artifactId> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-client</artifactId> </dependency> <!-- Spring Boot End --> <!-- Spring Cloud Begin --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zipkin</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <!-- Spring Cloud End --> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.ycq.hello.spring.cloud.admin.client.AdminClientApplication</mainClass> </configuration> </plugin> </plugins> </build> </project>
主要增加了 2 个依赖，org.jolokia:jolokia-core、de.codecentric:spring-boot-admin-starter-client
<dependency> <groupId>org.jolokia</groupId> <artifactId>jolokia-core</artifactId> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-starter-client</artifactId> </dependency>
其中 spring-boot-admin-starter-client 的版本号为：2.0.0，这里没写版本号是因为我已将版本号托管到 dependencies 项目中
Application
程序入口类没有特别需要修改的地方
package com.ycq.hello.spring.cloud.admin.client; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; @SpringBootApplication @EnableDiscoveryClient public class AdminClientApplication { public static void main(String[] args) { SpringApplication.run(AdminClientApplication.class, args); } }
application.yml
设置端口号为：8085，并设置 Spring Boot Admin 的服务端地址
spring: application: name: hello-spring-cloud-admin-client boot: admin: client: url: http://localhost:8084 zipkin: base-url: http://localhost:9411 server: port: 8085 eureka: client: serviceUrl: defaultZone: http://localhost:8761/eureka/ 主要增加了 Spring Boot Admin Client 相关配置 spring: boot: admin: client: url: http://localhost:8084
测试服务监控
一次启动两个应用，打开浏览器访问：http://localhost:8084 界面显示如下
从图中可以看到，我们的 Admin Client 已经上线了，至此说明监控中心搭建成功
