[GitHub] [servicecomb-java-chassis] myVictor opened a new issue #2139: @RequestBody 启动报错2.x
myVictor opened a new issue #2139:
URL: https://github.com/apache/servicecomb-java-chassis/issues/2139
Caused by: java.lang.IllegalStateException: generate swagger operation failed
我看springmvc标签支持表是支持的。 [](https://docs.servicecomb.io/java-chassis/zh_CN/build-provider/springmvc/)
@RequestMapping(value = "/result.action",produces = "application/json")
@ResponseBody
public ModelMap result(@RequestBody StudentVo studentVo)
这种写法问题在哪，应该怎么写？

可能是 StudentVo 存在抽象类和接口， 需要看下你的详细错误。 [类型支持说明参考](https://docs.servicecomb.io/java-chassis/zh_CN/build-provider/interface-constraints/)， 可以先了解下和 spring boot的差异。
