spring 使用@Valid校验数据出错DEBUG org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod

问题原因：在 @Valid 的那个参数后面紧跟着一个 BindingResult 的参数（一定要紧跟着）

正确的参数签名

    @PostMapping("publishPost.do")
    public String publishPost(@Valid @ModelAttribute Post post,
                              BindingResult bindingResult,
                              Errors errors, Model model, Integer tid,String action, RedirectAttributes attributes) {
