我尝试放置2请求映射，因为我想指向home / home，因为以后我将拥有另一个具有关于about / home的名称的控制器。但是我不确定为什么它不起作用。如果只有家，它正在工作，但家/家或关于/家不工作。该课程级别无法正常工作。
这个控制器
package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.constant.server.HelperConstant;
@Controller
@RequestMapping("/home")
public class HomeController
{
@RequestMapping("/home")
public String doDisplayPage()
{
return HelperConstant.VIEW_HOME;
}
}
这个jsp
<html>
<body>
<form action="home/home">
<input type="text" name="t1"><br>
<input type="text" name = "t2"><br>
<input type ="submit">
</form>
</body>
</html>

附加配置文件

public class WebConfig extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override

它是什么原因造成的？我该怎么办呢？
我正在使用数字角色U.are.U 5100指纹读取器。我面临的问题是，注册只会临时保存。如何将其保存到数据库？
