在实际开发过程中，我们需要更详细的版本对应：Spring 官方对应版本地址：  (https://start.spring.io/actuator/info)，建议用firefox浏览器打开，你会看见格式化好了json信息：

spring-cloud-dependencies 版本列表可查看：

spring-boot-starter-parent 版本列表可查看：

https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent

在SpringCloud中，1.X和2.X版本在pom.xml中引入的jar包名字都不一样，比如有的叫spirng-cloud-starter-hystrix 有的叫spring-cloud-netflix-hystrix，维护起来会比较困难。

1.x版本pom.xml里几个基本用到的jar长这样：

在SpringBoot 1.5.9.RELEASE 版本中，junit测试类模版长这样：

import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.web.client.RestTemplate;

@RunWith(SpringRunner.class)
@SpringBootTest(classes=MyApplication.class)
public class MyApplicationTest {
    private static final org.slf4j.Logger LOG = LoggerFactory.getLogger(MyApplicationTest.class);
    
    @Autowired
    private RestTemplate restTemplate;
    @Test
    public void test() {
        System.out.println("ok!!!");
    }
    @Test
    public void orderName() {
        try {
            String name = "joyce";
            String rr = restTemplate.getForObject("http://joyce-user/orderName?name="+name, String.class);
            LOG.info("rr====" + rr);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
}
