用過spring boot admin2.0的人 再回去用spring boot admin 1.5 就會感覺像是退化了一樣，但是默認(rèn)情況下spring boot 1.5.x不能使用 admin2.0的內(nèi)容

下面是頁面對比

這是admin1.5的頁面 用angular.js寫的 雖然功能都有 但是頁面難看

這是2.0的頁面是不是比1.5好看不少

我現(xiàn)在的想法是還是用spring boot1.5 但是 使用admin2.0的功能
首先創(chuàng)建一個spring boot項目 作為admin的server端
pom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"

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

啟動類上加上spring-boot-admin的配置

package com.example.demo;

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration
@EnableAdminServer
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

application.properties配置如下

server.port=1125
spring.application.name= admin2.0

接下來再創(chuàng)建一個spring boot項目使用spring boot 1.5版本
pom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"

            </plugin>
        </plugins>
    </build>
</project>

啟動類上不需要做任何配置
重點說一下application.properties配置

spring.boot.admin.auto-registration = true
spring.boot.admin.url = http://localhost:1125
spring.boot.admin.api-path = instances
management.security.enabled = false

注意，這里的配置嚴(yán)格按照這種寫法。當(dāng)然application.name和server.port還是要自己指定。
現(xiàn)在啟動admin-server和當(dāng)前這個spirng boot1.5項目（我自己做了一個基于spirng boot 2.0的例子做對比）
