项目需要改造为微服务，选择Spring Cloud，先根据文末的参考资料（方志朋的博客），跑通很多示例程序。其中前两节就是服务注册与发现，服务消费者。代码写完，并启动后，可以通过访问 http://localhost:8764/hi?name=forezp ，达到需要的结果。
项目Spring Cloud改造主要过程如下：
- 创建微服务order-relation,

- 解决思路如下
改造 order-relation项目的OrderRelationApplication.java，使之可以跑通测试方法hi
OrderRelationApplication.java
package com.fhbean.restservice.orderrelation;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
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;
@Configuration
@PropertySource(value = {"classpath:config.properties","classpath:log4j.properties","classpath:upload.properties"},
ignoreResourceNotFound = true)
@ComponentScan(basePackages = "com.fhbean.restservice.orderrelation.service,com.fhbean.restservice")
@MapperScan("com.chinaunicom.wsp.restservice.orderrelation.dao")
@EnableEurekaClient
@SpringBootApplication
@RestController
public class OrderRelationApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(OrderRelationApplication.class, args);
}
@RequestMapping(value = "/hi", method = RequestMethod.GET)
public String home(@RequestParam String name) {
return "hi " + name + ", I am from OrderRelationApplication";
}
}
order-relation-ribbon项目中，OrderRelationController.java，OrderRelationService.java已经在之前的代码中列出了hi方法。
重新启动项目，并访问http://localhost:8764/hi?name=80780b615c7e4b00683a9fc36428c00a，可以打出需要的结果。同时，http://localhost:8764/getOrderTime?userCode=80780b615c7e4b00683a9fc36428c00a，也正常了。说明结构没有问题，也没有少导哪个springboot包。
继续在order-relation项目查找问题的根源
把OrderRelationApplication.java类的hi方法注释，并重新启动order-relation项目。再次访问http://localhost:8764/getOrderTime?userCode=80780b615c7e4b00683a9fc36428c00a，正常。
经查是因为在OrderRelationApplication.java中增加了@RestController注解。
还有一个解决办法，就是在OrderRelationApplication.java中，扫描包中增加controller的包路径，即@ComponentScan(basePackages = "com.fhbean.restservice.orderrelation.controller,com.fhbean.restservice.orderrelation.service,com.fhbean.restservice")
