在Windows下开发，没有curl工具，因此如果把中间部分注释掉

@RequestMapping("/validate.json")
@ResponseBody
public JsonData validate(TestVo vo) throws ParamException {
   log.info("validate");
    // SysAclModuleMapper moduleMapper = ApplicationContextHelper.popBean(SysAclModuleMapper.class);
    // SysAclModule module = moduleMapper.selectByPrimaryKey(1);
   log.info(JsonMapper.obj2String(module));
   BeanValidator.check(vo);

   return JsonData.success("test validate");
}

得到的结果如下：

HTTP Status 500 – Internal Server Error

Type Exception Report

如果加了就完全只剩下
