在eureka上构建provider服务

本文主要是介绍在eureka上构建provider服务，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.eureka父工程

<?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"><parent><artifactId>spring-cloud-action</artifactId><groupId>com.lq.springcloud</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>eureka</artifactId><packaging>pom</packaging><modules><module>eureka-server</module><module>eureka-server-ha</module><module>eureka-provider</module></modules><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka-server</artifactId></dependency></dependencies></project>

2.eureka-server子工程

<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"><parent><artifactId>eureka</artifactId><groupId>com.lq.springcloud</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>eureka-server</artifactId><packaging>jar</packaging><name>eureka-server</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency></dependencies>
</project>

eureka-server启动类

package com.lq.springcloud;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaServer
@SpringBootApplicationpublic class EurekaServerApplication {public static void main(String[] args) {SpringApplication.run(EurekaServerApplication.class, args);}
}

eureka-server的application.properties

spring.application.name=eureka
server.port=8761
#是否将自己注册到eureka-server 默认为true
eureka.client.registerWithEureka=false 
#是否从eureka-server获取注册信息，默认为true
eureka.client.fetchRegistry=false

3.eureka-provider子工程

<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"><parent><artifactId>eureka</artifactId><groupId>com.lq.springcloud</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>eureka-provider</artifactId><packaging>jar</packaging><name>eureka-provider</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency></dependencies>
</project>

eureka-provider启动类

package com.lq.springcloud;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaClient
@SpringBootApplicationpublic class EurekaProviderApplication {public static void main(String[] args) {SpringApplication.run(EurekaProviderApplication.class, args);}
}

eureka-provider的application.properties

spring.application.name=eureka-provider
server.port=8080eureka.client.serviceUrl.defaultZone=http://127.0.0.1:8761/eureka/

eureka-provider提供的接口

package com.lq.springcloud.controller;import com.lq.springcloud.domain.Product;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;import java.util.ArrayList;
import java.util.List;@RestController
public class ProductController {@RequestMapping(value = "/getProducts",method = RequestMethod.GET)public List<Product> getProducts(){List<Product> list = new ArrayList<Product>();Product product1 = new Product("苹果",8000);Product product2 = new Product("苹果",2000);list.add(product1);list.add(product2);return list;}
}

package com.lq.springcloud.domain;public class Product {private String name;private int price;public Product(String name, int price) {this.name = name;this.price = price;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getPrice() {return price;}public void setPrice(int price) {this.price = price;}
}
