我正在开发一个简单的Java Web应用程序，该应用程序允许用户在文本框中输入一些信息，并在提交输入的文本时在另一个页面（success.jsp）中回显。我在StackOverflow中已经提到了许多教程和问题，但是无法完成。你能帮我这个忙吗？我想将文本从jsp中的表单提交到SpringMVC控制器。Maven用于依赖项管理。非常感谢mainController.javaimport org.springframework.context.annotation.Configuration;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod; @Controllerpublic class mainController { @RequestMapping(value = "/", method = RequestMethod.GET) public String index(Map<String, Object> model){ textConv textconv = new textConv(); model.put("textcovn", textconv); return "index"; } @RequestMapping(value = "/translate", method = RequestMethod.POST) public String translate(@ModelAttribute("textconv") textConv textconv, Map<String, Object> model){ System.out.println(textconv.getTextFrom()); return "success"; }}textConv.javapublic class textConv { String textFrom; public String getTextFrom() { return textFrom; } public void setTextFrom(String textFrom) { this.textFrom = textFrom; }}index.jsp<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Registration</title></head><body><h3>Enter text</h3> <form action="translate" method="POST" commandName="textconv"> <textarea rows="4" cols="50" path="textFrom">Enter text here</textarea> <input type="submit" value="Echo"></form></body></html>
