2.2 application.yml
eureka:
client:
fetch-registry: false # 從註冊中心獲取服務(註冊中心server爲自身,不需要開啓)
register-with-eureka: false # 註冊到註冊中心(註冊中心server自身,無需註冊到註冊中心)
service-url:
defaultZone: http://localhost:8090/eureka/eureka # 與Eureka server(註冊中心)交互地址,查詢Eureka服務的地址
instance:
hostname: localhost # 指定主機地址
2.3 啓動類
package com.personal.microspersonaleureka;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@SpringBootApplication
@EnableEurekaServer
public class MicrospersonalEurekaApplication {
static Logger logger = LoggerFactory.getLogger(MicrospersonalEurekaApplication.class);
public static void main(String[] args) {
SpringApplication.run(MicrospersonalEurekaApplication.class, args);
logger.info("註冊中心Eureka啓動");
}
}
3 Admin服務端
3.1 pom.xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-starter-server</artifactId>
<version>2.2.3</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
</dependencies>
3.2 application.yml
Admin自身監控自身,由於Admin配置了Security,因此在元數據metadata-map中添加賬密.
Admin監控的所有服務來自與Eureka註冊中心,而Admin自身也會註冊到Eureka,所以,會出現自身監控自身的情況.
eureka:
client:
service-url:
defaultZone: http://localhost:8090/eureka/eureka
instance:
metadata-map:
user.name: ${spring.security.user.name}
user.password: ${spring.security.user.password}
management:
endpoints:
web:
exposure:
include: "*"
endpoint:
health:
show-details: ALWAYS
序號 | 參數 | 描述 |
---|---|---|
1 | 端口 | Admin服務端端口 |
2 | username | 登錄Admin服務端的用戶名 |
3 | password | 登錄Admin服務端的密碼 |
3.3 Security配置
配置Admin服務端登錄權限.
package com.personal.microspersonaladmin.config;
import de.codecentric.boot.admin.server.config.AdminServerProperties;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
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
public class SpringAdminConfig extends WebSecurityConfigurerAdapter {
private final String adminContextPath;
public SpringAdminConfig(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/**",
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(
"/instances",
"/actuator/**",
adminContextPath + "/logout"
);
}
}
3.4 啓動文件
package com.personal.microspersonaladmin;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
// @EnableEurekaClient
@EnableAdminServer
// @EnableDiscoveryClient
public class MicrospersonalAdminApplication {
static Logger logger = LoggerFactory.getLogger(MicrospersonalAdminApplication.class);
public static void main(String[] args) {
SpringApplication.run(MicrospersonalAdminApplication.class, args);
logger.info("ADMIN啓動");
}
}
4 應用

- 地址
http://localhost:8090/eureka/
- 管理的服務
4.3 登錄Admin服務端
- 地址
http://localhost:8008
- 登錄界面
4.3 服務列表
4.4 服務面板牆
4.5 服務日誌信息
4.6 URI列表
