网上整合Spring Boot Admin的例子大部分都是Eureka Server注册中心一个服务， Spring Boot Admin作为另一个服务注册到Eureka Server上。
现在展示如何将Spring Boot Admin和Eureka Server整合到同一个服务上，步骤如下：
- 新建spcloud-eureka-spboot-admin-8761模块，新增pom.xml。

- 新增application.yml。 重点是eureka.dashboard.enabled设置为false，避免影响到springboot admin首页的访问。
server:
port: 8761
spring:
application:
name: spcloud-eureka-server-spboot-admin-8761
# 结合 Spring Security 实现需要用户名和密码登录的安全认证
security:
user:
name: "admin"
password: "admin"
# 设置springboot admin的信息，没啥用
# boot:
# admin:
# context-path: /admin # admin界面与eureka分离
eureka:
dashboard:
# 禁用eureka服务控制台，整合springboot admin关键配置，否则会影响springboot admin首页的访问
enabled: false
client:
healthcheck:
enabled: true
service-url:
# defaultZone: http://admin:admin@localhost:8761/eureka/
defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka/
# 获取注册信息，这里因为admin需要获取所以设置为true
# （启动的时候会报错，没关系，后面eureka server启动后就不会报错）
fetch-registry: true
# 单实例情况不需要相互注册，这里因为admin端需要被发现所以注册上
register-with-eureka: true
# 获取注册信息时间间隔，单位为秒
registryFetchIntervalSeconds: 5
instance:
hostname: localhost
# 显示访问路径的 ip 地址
prefer-ip-address: true
# 向注册中心发送心跳时间间隔，单位为秒
leaseRenewalIntervalInSeconds: 10
health-check-url-path: /actuator/health
metadata-map:
user.name: ${spring.security.user.name}
user.password: ${spring.security.user.password}
# 与Spring Boot 2一样，默认情况下，大多数actuator的端口都不会通过http公开
# * 代表公开所有这些端点。对于生产环境，应该仔细选择要公开的端点
# 暴露所有端点信息，不然在页面中无法查看监控数据
management:
endpoints:
web:
exposure:
include: "*"
endpoint:
health:
show-details: ALWAYS
- 新增配置类。
/**
* web安全相关配置
* 包括springboot admin登录相关配置
* @author bleachin
*/
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private final String adminContextPath; // 对应的配置项：spring.boot.admin.context-path
public WebSecurityConfig(AdminServerProperties adminServerProperties) {
this.adminContextPath = adminServerProperties.getContextPath();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
// http.httpBasic()
// .and().authorizeRequests()
// .anyRequest().permitAll()
// .and().csrf().disable();
// 登录成功之后重定向到applications页
SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
successHandler.setTargetUrlParameter("redirectTo");
successHandler.setDefaultTargetUrl(adminContextPath + "/applications");
http.authorizeRequests()
// 授予对所有静态资源、登录页面的公共访问权限
.antMatchers(adminContextPath + "/assets/**").permitAll()
.antMatchers(adminContextPath + "/login").permitAll()
// 这里根据你的实际情况暴露对应需要监控的服务
.antMatchers("/actuator/**").permitAll()
// 除了以上配置的，其他的请求必须进行身份验证
.anyRequest().authenticated()
.and()
// 配置登录和注销
.formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler)
.and()
.logout().logoutUrl(adminContextPath + "/logout")
.and()
// 启用HTTP-Basic支持。这是Spring Boot Admin Client注册所必需的
.httpBasic()
.and()
// 关闭跨站请求伪造，否则登录会失败
.csrf().disable();
// System.out.println("adminContextPath：" + adminContextPath);
// SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
// successHandler.setTargetUrlParameter("redirectTo");
// http.authorizeRequests()
// .antMatchers(adminContextPath + "/assets/**").permitAll()
// .antMatchers(adminContextPath + "/login").permitAll()
// .antMatchers(adminContextPath + "/eureka/**").permitAll()
// .anyRequest().authenticated()
// .and()
// .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler)
// .and()
// .logout().logoutUrl(adminContextPath + "/logout")
// .and()
// .httpBasic()
// .and()
// .csrf()
// .ignoringAntMatchers(adminContextPath + "/instances", adminContextPath + "/actuator/**")
// .disable();
}
}
- 新增启动类，加上@EnableEurekaServer服务注册中心注解、@EnableAdminServer admin服务注解，此处不用加@EnableDiscoveryClient，加入eureka client依赖会自动开启服务注册。
@SpringBootApplication
@EnableEurekaServer
@EnableAdminServer
public class SpcloudEurekaSpbootAdmin8761Application {
public static void main(String[] args) {
SpringApplication.run(SpcloudEurekaSpbootAdmin8761Application.class, args);
}
}
- 测试验证。
启动。
浏览器访问：http://localhost:8761/login
账号密码：
admin
admin
登录后，界面会跳转到：http://localhost:8761/applications
界面如下：
