I am adding this answer so that you can accept it, as it was suggested by Bozho :)
我正在添加这个答案，以便您可以接受它，正如 Bozho 所建议的 :)
There seems to be a problem in the HTML:
<input type="text name="text">
HTML 中似乎有问题：
<input type="text name="text">
Change it to
<input type="text" name="text">and try .
将其更改为
<input type="text" name="text">并尝试。
I think syntactically incorrect means the names specified in the @RequestParamannotations don't match with the request param names... possibly because of the above error in HTML.
我认为语法不正确意味着@RequestParam注释中指定的名称与请求参数名称不匹配......可能是因为 HTML 中的上述错误。
