spring-cloud-eureka服务发现注册中心及spring-cloud微服务

spring-cloud 使用eureka作为服务注册与发现中心，与zookeeper不同，eureka没有提供可直接运行的压缩文件，需要我们手动搭建eureka服务器。spring-cloud 与dubbo区别参考 https://www.cnblogs.com/aspirant/p/9089146.html

eureka服务器的搭建很简单与一般的spring-boot应用相同，只是启动类需要加上EnableEurekaServer注解并加上相应的配置

下面是我的eureka服务器

首先新建eureka项目

application.properties    spring-cloud-eureka详细配置参考  https://www.cnblogs.com/chry/p/7992885.html

server.port=8761
#是否注册到eureka-server
eureka.client.register-with-eureka=false
#否从eureka服务器获取注册信息
eureka.client.fetch-registry=false
#在Eureka服务器获取不到集群里对等服务器上的实例时，需要等待的时间，单位为毫秒，默认为1000 * 60 * 5
eureka.server.waitTimeInMsWhenSyncEmpty=0

启动类  spring-boot 2.0.0以上需要引入gson我没有引用所以在exclude 加入了GsonAutoConfiguration

package com.wl.springcloud.eureka;

        GsonAutoConfiguration.class                      //2.0.0以上版本需要引入高版本的gson依赖，如果不引用gson依赖需要加此属性
},scanBasePackages = "com.wl")
@EnableEurekaServer
public class EurekaApplication {

    private static final Logger logger = LoggerFactory.getLogger(EurekaApplication.class);

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(EurekaApplication.class);
        app.setWebApplicationType(WebApplicationType.SERVLET);
        app.run(args);
        logger.info("application init success");
    }

}

注意EnableEurekaServer注解

可以看到没有 实例注册到eureka上

下面我们新建一个client工程作为服务提供者注册到eureka（本身也是一个消费者这里我只用作提供者）spring-cloud微服务采用rest协议所以每一个微服务都是一个web工程

配置application.properties

server.port=8764
eureka.client.serviceUrl.defaultZone=http\://localhost\:8761/eureka/
spring.application.name=provider-client
eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true

defaultZone是指定eureka服务器的地址，无论是注册还是发现服务都需要这个地址。spring.application.name是指定进行服务注册时该服务的名称

启动类

package com.wl.springcloud.client;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**

 */
@SpringBootApplication(exclude = {
        DataSourceAutoConfiguration.class,
        DataSourceTransactionManagerAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class,             //不使用数据库
        GsonAutoConfiguration.class                      //spring-boot2.0.0以上版本需要引入高版本的gson依赖，如果不引用gson依赖需要加此属性
},scanBasePackages = "com.wl")
@EnableDiscoveryClient
public class ProviderApplication {
    private static final Logger logger = LoggerFactory.getLogger(ProviderApplication.class);

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(ProviderApplication.class);
        app.setWebApplicationType(WebApplicationType.SERVLET);
        app.run(args);
        logger.info("application init success");
    }

    
}

注意EnableDiscoveryClient注解，只有加了这个注解eureka服务器才会注册此服务

下面新建一个controller作为提供接口

package com.wl.springcloud.client;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2019/3/10.
 */
@RestController
public class ProviderController {
    

    private Environment environment;

    @Autowired
    public ProviderController(Environment environment){
        this.environment = environment;
    }

    @RequestMapping("/provider")
    public String provider(){
        return "provider server port:" + environment.getProperty("server.port");
    }
    

}

 现在我们需要一个消费者应用来消费这个服务(spring-cloud为服务采用rest协议，所以消费者与提供者之间使用RestTemplate通信)

新建工程consume-client（与上面的client一样）

@SpringBootApplication(exclude = {

},scanBasePackages = "com.wl")
@EnableDiscoveryClient
public class ConsumeApplication {
    private static final Logger logger = LoggerFactory.getLogger(ConsumeApplication.class);

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(ConsumeApplication.class);
        app.setWebApplicationType(WebApplicationType.SERVLET);
        app.run(args);
        logger.info("application init success");
    }

    @LoadBalanced
    @Bean
    public RestTemplate restTemplate(){
        return new RestTemplate();
    }

}

consumeController

package com.wl.springcloud.comsumeclient;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

/**
 * Created by Administrator on 2019/3/11.
 */
@RestController
public class ConsumeController {

    private RestTemplate restTemplate;

    @Autowired
    public ConsumeController(RestTemplate restTemplate){
        this.restTemplate = restTemplate;
    }

    private static final String SERVER_NAME = "provider-client";
    
    @RequestMapping("/consume")
    public String consume(){
        String provider = restTemplate.getForObject("http://" + SERVER_NAME +"/provider",String.class);
        return "consume - " + provider;
    }
    

}

注意SERVER_NAME为上面client工程application.properties中的spring.application.name

可以看到使用restTemplate只用指定协议+服务名称+对应的路径就可以访问spring-cloud微服务（与直接localhost:8764/provider不同，不用指定端口和host）
