Spring Boot Admin和Nacos集成

摘要:本文主要讲解如何将Spring Boot Admin与Spring Cloud Alibaba中的spring-cloud-starter-alibaba-nacos-discovery进行整合使用。

1. 整合概述

通过搭建一个Spring Boot Admin Server，并将其通过spring-cloud-starter-alibaba-nacos-discovery注册到Nacos Server中即可。源码工程地址为:https://github.com/SoftwareKing/sba-nacos

说明本文使用的Spring Boot Admin的版本为2.1.2，Spring Cloud的版本为Greenwich.RELEASE，Spring Cloud Alibaba的版本为0.2.1.RELEASE。至于其它版本，请读者自行适配处理。

2. 创建sba-nacos工程

1.创建sba-nacos工程，添加maven依赖如下所示:

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <artifactId>sba-nacos</artifactId>

    <properties>
        <spring.boot.admin.version>2.1.2</spring.boot.admin.version>
    </properties>

                <version>0.2.1.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>

            <artifactId>spring-boot-starter-actuator</artifactId>

        <dependency>

            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

        <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-server</artifactId>
            <version>${spring.boot.admin.version}</version>
        </dependency>

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

        <dependency>
            <groupId>org.jolokia</groupId>

    <build>
        <finalName>sba-nacos</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

创建主入口程序，代码如下所示:

package org.xujin.moss.nacos;

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;


@SpringBootApplication
@EnableAdminServer
@EnableDiscoveryClient
public class MossNacosApplication {
    public static void main(String[] args) {
        SpringApplication.run(MossNacosApplication.class, args);
    }
}

3.application.yml配置如下所示:

spring:
    application:
        name: sba-nacos
    cloud:
      nacos:
        discovery:
          server-addr: 127.0.0.1:8848

server:
    port: 8080 #启动端口
