springcloud(Brixton版) EurekaServer 消费端-蒲公英云

springcloud(Brixton版) EurekaServer 消费端

1.创建springboot项目。

2.pom.xml

<?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.didispace</groupId>
   <artifactId>compute-service</artifactId>
   <version>1.0.0</version>
   <packaging>jar</packaging>
   <name>compute-service</name>
   <description>Spring Cloud project</description>
   <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.3.5.RELEASE</version>
      <relativePath/> <!-- lookup parent from repository -->
   </parent>
   <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      <java.version>1.8</java.version>
   </properties>
   <dependencies>
      <dependency>
         <groupId>org.springframework.cloud</groupId>
         <artifactId>spring-cloud-starter-eureka</artifactId>
      </dependency>
      <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-test</artifactId>
         <scope>test</scope>
      </dependency>
   </dependencies>
   <dependencyManagement>
      <dependencies>
         <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Brixton.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
         </dependency>
      </dependencies>
   </dependencyManagement>
   <build>
      <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
   </build>
</project>

3.application.properties

spring.application.name=compute-service
server.port=2222
eureka.client.serviceUrl.defaultZone=http://localhost:1111/eureka/

4.controller（这里简单的进行计算两数之和的逻辑处理）

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ComputeController {
    private final Logger logger = Logger.getLogger(getClass());
    @Autowired
    private DiscoveryClient client;
    @RequestMapping(value = "/add" ,method = RequestMethod.GET)
    public Integer add(@RequestParam Integer a, @RequestParam Integer b) {
        ServiceInstance instance = client.getLocalServiceInstance();
        Integer r = a + b;
        logger.info("/add, host:" + instance.getHost() + ", service_id:" + instance.getServiceId() + ", result:" + r);
        return r;
    }
}

5.启动类：

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@EnableDiscoveryClient
@SpringBootApplication
public class ComputeServiceApplication {
   public static void main(String[] args) {
      new SpringApplicationBuilder(ComputeServiceApplication.class).web(true).run(args);
   }
}

6.启动项目，访问http://localhost:1111/ 则可以看见被注册到了eureka服务端。

接着访问：http://192.168.8.1:2222/add?a=1&b=2

2019-09-28 16:37:02.654 INFO 9620 —- [nio-2222-exec-5] com.didispace.web.ComputeController : /add, host:192.168.8.1, service_id:compute-service, result:3

这样就完成了服务端和消费端的简单实现。
