返回代码参考：return ResponseEntity.status(status).body(message)；

下面有个例子可以参考下：
```
@ResponseHeaders({@ResponseHeader(name = "h1", response = String.class),
@ResponseHeader(name = "h2", response = String.class)})
@RequestMapping(path = "/responseEntity", method = RequestMethod.POST)
public ResponseEntity<Date> responseEntity(InvocationContext c1, @RequestAttribute("date") Date date) {
HttpHeaders headers = new HttpHeaders();
headers.add("h1", "h1v " + c1.getContext().get(Const.SRC_MICROSERVICE));
InvocationContext c2 = ContextUtils.getInvocationContext();
headers.add("h2", "h2v " + c2.getContext().get(Const.SRC_MICROSERVICE));
return new ResponseEntity<>(date, headers, HttpStatus.ACCEPTED);
}
```
注意：
1. 需要显示声明ResponseEntity的模板类型；
2. 如果还需要返回额外的headers，需要通过ResponseHeaders显示的声明返回的header。
这个是java-chassis和Spring MVC不同的地方， 接口定义需要是明确的，能够通过契约描述出来实际的类型和header。

通过这样返回，在前端查看Body为空。不是null，是啥都没有。
public static ResponseEntity<String> getResponseEntity(XXXXException e) {
return ResponseEntity.status(HttpStatus.valueOf(e.getCode())).body(e.getMsg());
}
改成这样抛出异常，前端是可以获取到Body的：
throw new InvocationException(e.getCode(), e.getMessage(), e.getMsg());

能将完整的接口原型定义和客户端调用方式的代码贴一下吗？
