## 学习点 ##

1，domain-XML互相组建构建  
2，feign以XML形式传输

## 简介 ##

<table> 
 <thead> 
  <tr> 
   <th>项目名</th> 
   <th>描述</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>eureka-demo</td> 
   <td>eureka注册中心</td> 
  </tr> 
  <tr> 
   <td>eureka-service</td> 
   <td>服务生产者</td> 
  </tr> 
  <tr> 
   <td>feign-client</td> 
   <td>消费者</td> 
  </tr> 
 </tbody> 
</table>

## 1.引入依赖 ##

项目中用到jackson解析XML以及组建XML

<dependency>
         	<groupId>com.fasterxml.jackson.dataformat</groupId>
                <artifactId>jackson-dataformat-xml</artifactId>
                <version>2.8.8</version>
    </dependency>

## 2.思路 ##

(1)要想以XML形式传输，首先需要先构建XML结构体，[domain注解构建XML][domain_XML]  
(2)构建好XML结构体后，考虑feign传输XML，restful接口接收XML结构体的方法  
方法如下：  
示例：

@FeignClient("eureka-service")
    public interface MemberFeign {
    
    	@GetMapping(value = "/getUserList",produces = MediaType.APPLICATION_JSON_VALUE,consumes = MediaType.APPLICATION_XML_VALUE)
    	public List<String> getOrderByUserList(Member member);
    
    	@PostMapping(value = "/cov", consumes = { MediaType.APPLICATION_XML_VALUE }, produces = MediaType.APPLICATION_JSON_VALUE)
    	public BuildEntity sendCovBody(@RequestBody BuildEntity buildEntity);
    
    }

如上示例中重点在于`consumes = { MediaType.APPLICATION_XML_VALUE }, produces = MediaType.APPLICATION_JSON_VALUE`

<table> 
 <thead> 
  <tr> 
   <th></th> 
   <th></th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>consumes</td> 
   <td>表示调用服务eureka-service的接口 /cov接口，需要XML格式入参</td> 
  </tr> 
  <tr> 
   <td>produces</td> 
   <td>表示调用服务 eureka-service的接口 /cov接口，返回格式时j son</td> 
  </tr> 
 </tbody> 
</table>
