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Maven依赖

• 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}}
  boot:
    admin:
      discovery:
        ignored-services: consul
      routes:
        endpoints: env,metrics,trace,dump,jolokia,info,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream,turbine.stream
      turbine:
        clusters: default
        location: admin-dashboard

management:
  security:
    enabled: false

turbine:
  cluster-name-expression: new String("default")
  app-config: service-goods, service-order, service-wechat-admin

security:
  user:
    name: 登录用户名
    password: 登录密码

• 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();

    }
}

被监控服务的配置

被监控的服务需要配置如下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
