springbootadmin的使用（非微服务版）

springbootadmin的使用（非微服务版）

Spring Boot Admin是一个开源社区项目，用于管理和监控SpringBoot应用程序 同样，也可通过springcloud注册中心（如nacos）使用，使用简单功能强大

本文着重测试非微服务的使用

SpringBoot Admin分为server和client两个，server端引入ui操作，而client端则向server注册和提供信息

server端搭建

 <!-- admin server 依赖 -->
<dependency>
      <groupId>de.codecentric</groupId>
      <artifactId>spring-boot-admin-starter-server</artifactId>
      <version>2.2.2</version>
</dependency>

启动类添加注解@EnableAdminServer

server:
  port: 8080
spring:
  application:
    name: xueya-server
  boot:
    admin:
      ui:
        # ui页面的自定义内容信息
        title: 我的服务监控中心
        brand: <span>Service Center</span>

client端搭建

注意：client端可以和server端在同一个服务中

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

<dependency>
      <groupId>de.codecentric</groupId>
      <artifactId>spring-boot-admin-starter-client
	 </artifactId>
</dependency>

spring:
  application:
    name: xueya-server
  boot:
    admin:
      client:
        # spring boot admin server的注册地址
		#多个以逗号隔开
		#并把localhost换成ip
        url: http://localhost:8080

#需要暴露监控端口给spring boot admin server访问
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: ALWAYS

访问测试

配置完成后，访问http://localhost:8080

实时日志输出

这个功能确实让人眼前一亮，配置也不复杂，如下：

#yaml里面新增
logging:
  #spring admin boot日志输出配置
  #需要跟logback-spring.xml配置中日志路径一致
  file:
    name: logs/suntae-oauth/error.log

引入security授权访问

下面是一个例子： 在server端引入pom

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

加入密码访问

spring:
  security:
    user:
      name: coding-farmer
      password: 123456

添加security配置

package com.springcloudlearn;
import de.codecentric.boot.admin.server.config.AdminServerProperties;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
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;
import org.springframework.security.web.csrf.CookieCsrfTokenRepository;
@EnableAdminServer
@SpringBootApplication
public class SpringbootAdminServerApplication {
  public static void main(String[] args) {
    SpringApplication.run(SpringbootAdminServerApplication.class, args);
  }
  @Configuration
  public static class SecuritySecureConfig extends WebSecurityConfigurerAdapter {
    private final String adminContextPath;
    public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
      this.adminContextPath = adminServerProperties.getContextPath();
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
      // @formatter:off
      SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
      successHandler.setTargetUrlParameter("redirectTo");
      successHandler.setDefaultTargetUrl(adminContextPath + "/");
      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()
          .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
          .ignoringAntMatchers(
              adminContextPath + "/instances",
              adminContextPath + "/actuator/**"
          );
      // @formatter:on
    }
  }
}

由于服务端配置了密码，客户端访问的时候需要密码，这是基于SBA访问模式，也就是所谓的直接连接springboot admin服务端模式，在application.yml文件中添加username，password

spring:
  application:
    name: xueya-server
  boot:
    admin:
      client:
        url: http://localhost:8080
        username: coding-farmer
        password: 123456

总结

以上都是最基础的使用，我们可以引入javaMail发送邮件等等 若想显示更加详细的信息，请在clent端引入pom依赖：

<!-- 系统健康检测模块依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
