SpringCloud-Finchley使用SpringBootAdmin監控各個微服務

1.建立夫工程SpringCloudAdmin，pom文件爲

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </plugin>
        </plugins>
    </build>


</project>

2.建立子工程server-admin，pom文件爲

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.xueqing.demo</groupId>
    <artifactId>service-admin</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>service-admin</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>com.xueqing.demo</groupId>
        <artifactId>springcloudadmin</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>


    <dependencies>

        </dependency>

        <dependency>

            </plugin>
        </plugins>
    </build>


</project>

3.server-admin中啓動類爲

package com.xueqing.demo.serviceadmin;

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;

@EnableAdminServer
@SpringBootApplication
public class ServiceAdminApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServiceAdminApplication.class, args);
    }
}

4.配置admin的登陸

package com.xueqing.demo.serviceadmin;

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 {
        // @formatter:off
        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();
        // @formatter:on
    }

}

5.application.yml配置文件爲

server:
  port: 5000
spring:
  application:
    name: admin-server
  security:
    user:
      name: 'admin'
      password: 'admin'
eureka:
  client:
    registryFetchIntervalSeconds: 5
    service-url:
      defaultZone: ${EUREKA_SERVICE_URL:http://peer1:8761}/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health
    metadata-map:
      user.name: ${spring.security.user.name}
      user.password: ${spring.security.user.password}

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS

6.創建client-admin-one和client-admin-two，兩個子工程一致，以one爲例，pom

        </plugins>
    </build>


</project>

7.spring啓動類

package com.xueqing.demo.clientoneadmin;

import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class ClientOneAdminApplication {

    public static void main(String[] args) {
        SpringApplication.run(ClientOneAdminApplication.class, args);
    }

        @Value("${server.port}")
    String port;
    @GetMapping("/hi")
    @HystrixCommand(fallbackMethod = "hiError")
    public String hi(@RequestParam(required = false,defaultValue = "cralor")String name){
        return "hi "+name+",i am client one and from port:"+port;
    }
    public String hiError(String name){
        return "hi "+name+",sorry,error!";
    }
}

8.application配置文件

server:
  port: 8963
spring:
  application:
    name: client-admin-two
  boot:
    admin:
      client:
        url: http://localhost:5000
eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10 #表示eureka client發送心跳給server端的頻率，默認爲30秒
    health-check-url-path: /actuator/health #健康檢查的地址（依賴spring-boot-starter-actuator）
  client:
    registryFetchIntervalSeconds: 5 #表示eureka client間隔多久去拉取服務註冊信息，默認爲30秒
    service-url:
      defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: ALWAYS

9.訪問localhost:5000 用戶名admin，密碼admin。驗證admin是否正常
