1. 添加依赖
首先,在你的admin服务端pom.xml文件中添加Spring Boot Admin的依赖:
            
            
              XML
              
              
            
          
          <dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-server</artifactId>
    <version>2.5.4</version> <!-- 请根据实际情况选择最新版本 -->
</dependency>
        2. 配置Spring Boot Admin Server
在你的Spring Boot应用中,启用Spring Boot Admin Server:
            
            
              java
              
              
            
          
          import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableAdminServer
public class AdminServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminServerApplication.class, args);
    }
}
        3. 配置Spring Boot Admin Client
如果你想要将你的应用注册为Spring Boot Admin的客户端,还需要添加以下依赖:
            
            
              XML
              
              
            
          
          <dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-client</artifactId>
    <version>2.5.4</version> <!-- 请根据实际情况选择最新版本 -->
</dependency>
        如果你想要将你的应用注册为Spring Boot Admin的客户端,需要在application.yml或application.properties文件中进行配置:
            
            
              javascript
              
              
            
          
          
spring:
  boot:
    admin:
      client:
        url: http://localhost:8080  # Spring Boot Admin Server的地址
        4. 启动应用
启动Spring Boot Admin Server和客户端应用后,访问Spring Boot Admin Server的地址(例如:http://localhost:8080),你将看到注册的客户端应用及其监控信息。
5. 安全配置(可选)
如果你想要保护Spring Boot Admin Server的访问,可以添加Spring Security依赖并进行配置:
            
            
              XML
              
              
            
          
          <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
        然后在application.yml中配置用户名和密码:
            
            
              javascript
              
              
            
          
          spring:
  security:
    user:
      name: admin
      password: password
        最后,创建一个Spring Security配置类来保护Admin Server的端点:
            
            
              java
              
              
            
          
          import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .httpBasic();
    }
}
