# 快速搭建微服务-服务监控

Spring Boot Admin为基于Spring Boot的基础数据安全端口提供了基础的可视化监控功能。还可以通过Spring Boot Admin的服务端程序对Spring Boot程序提供简单的实时管理(例如修改日志输出级别)。

# Spring Cloud集成Spring Boot Admin

# Spring Boot Admin服务端

Spring Cloud中集成Spring Boot Admin比较简单,只需要将服务端程序注册到注册中心即可。

  • 服务端配置
spring:
  application:
    name: admin-dashboard
  cloud:
    consul:
      discovery:
        instance-id: ${spring.application.name}:${spring.cloud.consul.discovery.instance_id:${random.value}}

  • 启动类

在服务端的启动类加上 @EnableAdminServer 注解声明当前程序为Spring Boot Admin服务端程序。启动类加上 @EnableTurbine 注解开启断路器监控数据的聚合展示。

  • 安全访问控制

上面的 spring-boot-admin-server-ui-login 提供了一个登录界面用于访问Spring Boot Admin。需要搭配 spring-security 一起使用。Spring Security的配置如下:

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .formLogin().loginPage("/login.html").loginProcessingUrl("/login")
                .successHandler((request, response, exception) -> response.sendRedirect(request.getContextPath() + "/index.html")).permitAll()
                .and()
                .logout().logoutUrl("/logout")
                .and()
                .authorizeRequests()
                .antMatchers("/login.html", "//*.css", "/img/", "/third-party/").permitAll()
                .anyRequest().authenticated()
                .and().httpBasic();

    }
}
