报错原因:@ApiModel(value="userVO") dataType = "UserVO" 两个名称不一致,导致没有对应起来,首字母一个大写,一个小写
解决方法:接口中的 dataType = "UserVO" 的dataType 的值
和实体类的 @ApiModel(value="UserVO") 的value的值要一致
@ApiModel(value="UserVO") public class UserVO {} @ApiOperation(value = "获取用户信息", notes = "获取用户信息") @ApiImplicitParams({ @ApiImplicitParam(name = "userVO", value = "用户参数", required = false, dataType = "UserVO", paramType = "body"), @ApiImplicitParam(name = "Accept", value = "接收属性", required = true, dataType = "String", paramType = "header", defaultValue = "application/json"), @ApiImplicitParam(name = "Accept-Charset", value = "接收字符集", required = true, dataType = "String", paramType = "header", defaultValue = "utf-8"), @ApiImplicitParam(name = "Content-Type", value = "内容类型", required = true, dataType = "String", paramType = "header", defaultValue = "application/json; charset=UTF-8") }) @RequestMapping(value = "/org/user", method = RequestMethod.POST, produces = "application/json;charset=UTF-8") @InterfaceApiLabel(value = "001", description = "获取用户信息") public List mergeUser(@RequestBody UserVO userVO, @RequestHeader HttpHeaders headers) { return null; }
