使用Spring MVC控制器映射JSP文本输入
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.java
import 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;
@Controller
public 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.java
public class textConv {
String textFrom;
public String getTextFrom() {
return textFrom;
}
public void setTextFrom(String textFrom) {
this.textFrom = textFrom;
}
}
index.jsp
