最佳答案
您正在尝试使用 get 方法发送表单，这会导致将搜索数据附加到 url:
Appends the form-data to the URL in name/value pairs: URL?name=value&name=value
http://www.w3schools.com/tags/att_form_method.asp
你能做的就是改变你的@RequestMapping并将表单方法设置为 POST，但更好的解决方案是将 Controller 方法更改为接受 Map<String, String>而不是@ModelAttribute :
@RequestMapping(value = "/deputeAppealSearchPageResult", method = RequestMethod.GET)
public String resultOfSearchingDeputeAppeal(Map<String, String> params, Model model)
您必须将数据重写到对象 DTO，或者更改您的服务以接受 Map<String,String> 。
这样会需要更多的重构，但解析会按照GET方法规范进行。
