SpringBootAdmin+actuator进行服务监控_springbootadmin请求/actuator带上了/instances前缀

SpringBootAdmin可以监控SpringBoot单击或集群项目，提供详细的健康信息、内存信息、JVM系统和环境属性、垃圾回收信息、日志设置和查看、定时任务查看、SpringBoot缓存查看和管理功能。

第一步：监控服务端搭建

        创建一个SpringBoot项目，添加下面依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
  <groupId>de.codecentric</groupId>
  <artifactId>spring-boot-admin-starter-server</artifactId>
</dependency>

        在启动类上开启监控服务

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@EnableAdminServer
@SpringBootApplication
public class SysadminApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(SysadminApplication.class, args);
        System.out.println("项目启动成功！");
    }
 
}

        在配置文件中只需要配置一个服务端口即可。配置端口的目的是为了不与其它服务冲突。

server.port=8081

         启动服务端，此时访问地址：http://localhost:8081/applications  界面如下

添加security支持，防止任意用户可查看监控。首先添加依赖

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

在配置文件中添加以下配置

# 设置登录用户名、密码和角色
spring.security.user.name=java666
spring.security.user.password=java666
spring.security.user.roles=SBA_ADMIN

最后，进行权限资源设置。在服务端创建类，加入下面代码即可

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.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.security.web.csrf.CookieCsrfTokenRepository;
 
@EnableWebSecurity
@Configuration(proxyBeanMethods = false)
public class AdminSecurityConfig extends WebSecurityConfigurerAdapter {
 
    private final String adminContextPath;
 
    public AdminSecurityConfig(AdminServerProperties adminServerProperties) {
        this.adminContextPath = adminServerProperties.getContextPath();
    }
 
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter("redirectTo");
        successHandler.setDefaultTargetUrl(adminContextPath + "/");
        http.authorizeRequests()
                .antMatchers(adminContextPath + "/assets/**").permitAll()
                .antMatchers(adminContextPath + "/login").permitAll()
                .antMatchers(adminContextPath + "/instances/**").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/**"
                );
    }
 
    @Override
    public void configure(WebSecurity web) {
        web.ignoring().antMatchers("/actuator/**");
    }
 
}

此时访问监控系统就需要输入用户名和密码才能正常使用。如下所示

 第二步：客户端搭建配置

        1、所需依赖

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

        2、在客户端配置文件中添加如下配置

        注意：如果是yml配置文件，在配置开启监控所有项的时候，*需要使用单引号包裹

# 当前项目端口号
server.port=8080
# Spring Boot Admin 监控服务器端地址
spring.boot.admin.client.url=http://localhost:8081
# 开启监控所有项，Actuator功能
management.endpoints.web.exposure.include=*

        3、启动项目，利用服务端主页地址查看即可http://localhost:8081/applications
