springcloud 微服务管理之 admin 实战使用（九）

Dear 丶 2022-12-02 15:24 127阅读 0赞

Springcloud admin 是基于spring-boot-starter-actuator 实现的， admin 是根据统计出来的数据来进行展示的，可以很好的监控整   
个微服务系统中的实例运行情况信息，前提结合注册中心才能拿到数据。

1、actuator 负责统计数据，引入jar:  
<dependency>   
<groupId>org.springframework.boot</groupId>   
<artifactId>spring-boot-starter-actuator</artifactId>   
</dependency>

<dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-server</artifactId>
        <version>LATEST</version>
    </dependency>
    
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-server-ui</artifactId>
        <version>LATEST</version>
    </dependency>

2、启动类配置：

import de.codecentric.boot.admin.server.config.EnableAdminServer;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    @SpringBootApplication
    @EnableEurekaClient
    @EnableAdminServer  //admin相关注解
    public class MicroAdminApplication {
        public static void main(String[] args) {
            SpringApplication.run(MicroAdminApplication.class,args);
        }
    }

3、核心安全配置：bootstrap.properties

# 安全配置，用户名和密码 可以自定义设置
    spring.security.user.name=admin
    spring.security.user.password=admin
    eureka.instance.metadata-map.user.name=${spring.security.user.name}
    eureka.instance.metadata-map.user.password=${spring.security.user.password}

其他配置：

spring.application.name=nandao-admin
    server.port=8282
    #是否注册到eureka
    eureka.client.registerWithEureka=true
    #是否从eureka中拉取注册信息
    eureka.client.fetchRegistry=true
    eureka.client.serviceUrl.defaultZone=http://admin:admin@localhost:8763/eureka/

安全效验的相关代码：

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.configuration.WebSecurityConfigurerAdapter;
    import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
    
    @Configuration
    public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {
    
        private final String adminContextPath;
    
        public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
            this.adminContextPath = adminServerProperties.getContextPath();
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
            successHandler.setTargetUrlParameter("redirectTo");
            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().disable();
        }
    }

4、启动admin、注册中心、客户端服务 访问 [http://localhost:8282][http_localhost_8282]:

登录后显示服务类表：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmRhbzE1OA_size_16_color_FFFFFF_t_70 1][]

点击  应用墙显示 服务模块，如果某个服务挂了，那么该模块会显示红色，大家可以测试一下
