启用 Spring Boot Admin Server
Maven用户可以将以下依赖项添加到pom.xml文件中。
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-server</artifactId>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-server-ui</artifactId>
</dependency>
Gradle用户依赖的代码如下
implementation 'de.codecentric:spring-boot-admin-server'
implementation 'de.codecentric:spring-boot-admin-server-ui'
在主Spring Boot应用程序类文件中添加@EnableAdminServer注解。@EnableAdminServer注解用于使您成为Admin Server来监视所有其他微服务。
package com.jc2182.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
@SpringBootApplication
@EnableAdminServer
public class AdminserverApplication {
public static void main(String[] args) {
SpringApplication.run(AdminserverApplication.class, args);
}
}
现在,在application.properties文件中定义server.port和应用程序名称,如下所示-
server.port = 9090
spring.application.name = adminserver
对于YAML用户,使用以下属性在application.yml文件中定义端口号和应用程序名称。
server:
port: 9090
spring:
application:
name: adminserver
生成配置文件如下。 对于Maven用户– pom.xml

对于Maven,请使用以下命令
在“BUILD SUCCESS”之后,您可以在target目录下找到JAR文件。
对于Gradle,请使用以下命令-
在“BUILD SUCCESSFUL”之后,您可以在build/libs目录下找到JAR文件。
现在,使用如下所示的命令运行JAR文件:
现在,该应用程序已在Tomcat端口9090上启动,如下所示-
现在,从Web浏览器中点击以下URL,然后查看Admin Server UI。 http://localhost:9090/
