   > 哦。 把你的意思理解反了。
   > @FormParam就是从body的form里面提取参数的。 但是你的问题很奇怪， 如果是服务端接收@FormParam， 那么客户端应该把参数使用form传输， 而客户如何构造请求，是客户端决定的。 不应该存在你说的问题。

   api如下
   ```public interface EngineElementHotDeployService {
       EngineElementHotDeployResponse hotDeploy(
           @ModelAttribute @Valid @NotNull @ApiParam("request") EngineElementHotDeployRequest request);
   }
   ```
   服务端实现如下
   ```@RestSchema(schemaId = "StudioHotDeployRpcService")
   @RequestMapping(value = ServiceConstants.SERVICE_URL_PREFIX + "/v1/protected/studio/hot-deploy")
   public class StudioHotDeployRpcServiceImpl implements EngineElementHotDeployService {
       @Override
       @PostMapping(produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
       public EngineElementHotDeployResponse hotDeploy(@ModelAttribute EngineElementHotDeployRequest request) {
           validate(request);
           return hotDeployEngine(request);
       }
   }
   ```
   
   客户端调用如下
   ```
   @RpcReference(microserviceName = "xxxx", schemaId = "StudioHotDeployRpcService")
   private ProjectHotDeployApiService hotDeployApiService;    
   
   private void hotDeploy(EngineElementHotDeployRequest request) {
           EngineElementHotDeployResponse response = hotDeployService.hotDeploy(request);
   }
   ```
