【Spring Boot Admin】使用（整合Spring Security服务，添加鉴权）

Spring Boot Admin 监控平台

背景：Spring Boot Admin 监控平台不添加鉴权就直接访问的话，是非常不安全的。所以在生产环境中使用时，需要添加鉴权，只有通过鉴权后才能监控客户端服务。本文整合Spring Security进行实现。

yml配置

server:
  port: 18000

spring:
  application:
    name: admin-server
  security:
    user:
      name: admin
      password: admin
  cloud:
    nacos:
      discovery:
        enabled: true
        server-addr: 127.0.0.1:8848
        group: admin  #指定group
        namespace: public
        service: ${spring.application.name}

启动类@EnableAdminServer

package com.admin;

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;

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

安全配置类：SecuritySecureConfig.java

package com.admin.config;

import de.codecentric.boot.admin.server.config.AdminServerProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;

@Configuration(proxyBeanMethods = false)
public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {

    private final String adminContextPath;

    public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
        this.adminContextPath = adminServerProperties.getContextPath();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter( "redirectTo" );

        http.authorizeRequests()
                .antMatchers( adminContextPath + "/assets/**" ).permitAll()
                .antMatchers( adminContextPath + "/login" ).permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage( adminContextPath + "/login" ).successHandler( successHandler ).and()
                .logout().logoutUrl( adminContextPath + "/logout" ).and()
                .httpBasic().and()
                .csrf().disable();
    }
}

服务启动成功后，访问链接：http://127.0.0.1:18000。需要先进行登录（admin-admin），才能进入控制台页面。

客户端服务

背景：客户端服务的检查接口（/actuator/**）默认可以直接通过接口调用，是非常不安全的。所以在生产环境中使用时，可添加鉴权功能提升安全性。

          metadata: 
            user.name: ${spring.security.user.name}
            user.password: ${spring.security.user.password}

yml配置（通过注册中心注册）

spring:
  security:
    user:
      name: user
      password: user
  application:
    name: admin-order
  cloud:
    nacos:
      discovery:
        metadata:
          # 为服务实例添加一个名为“user.name”的元数据项，并将其值设置为指定的服务用户名。这个用户名通常用于进行鉴权，以确保只有授权的用户才能访问该服务。
          user.name: ${spring.security.user.name}
          user.password: ${spring.security.user.password}
          management:
            # 表示Actuator端点的上下文路径。具体地说，这个属性的作用是将Actuator端点的上下文路径设置为${server.servlet.context-path}/actuator
            context-path: ${server.servlet.context-path}/actuator
        enabled: true
        server-addr: 127.0.0.1:8848
        group: admin  #指定group
        namespace: public
        service: ${spring.application.name}

server:
  port: 18001
  servlet:
    context-path: /order

#  endpoints config
management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

logging:
  # 只有配置了日志文件，才能被监控收集
  file:
    name: logs/${spring.application.name}/${spring.application.name}.log

启动类

package com.admin;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@Slf4j
@EnableDiscoveryClient
@SpringBootApplication
public class AdminOrderApp {
    public static void main(String[] args) {
        SpringApplication.run(AdminOrderApp.class, args);
    }
}

服务启动成功后，访问监控平台，就能监控admin-order服务了。

注意：如果监控平台上没有看见客户端服务，则需要重启Spring Boot Admin 监控服务
