@RequestParam 浏览器提交表单时，传入服务器的参数由@RequestParam携带
1. 承接上一篇的代码内容，在相同的包名下新建一个类StudentAdmissionController.java
package com.haha;
import java.util.Map;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class StudentAdmissionController{
@RequestMapping(value="/admissionForm.html",method = RequestMethod.GET)
public ModelAndView getAdmissionForm(){
ModelAndView model = new ModelAndView("AdmissionForm");
return model;
}
@RequestMapping(value="/submitAdmissionForm.html", method = RequestMethod.POST)
public ModelAndView submitAdmissionForm(@RequestParam Map<String,String> reqVar){
String name = reqVar.get("studentName");
String hobby = reqVar.get("studentHobby");
ModelAndView model = new ModelAndView("AdmissionSuccess");
model.addObject("msg","Details submitted by you::Name: "+ name+", Hobby: "+hobby);
return model;
}
}
2. 在WEB-INF目录下新建表单页面AdmissionSuccess.jsp
<html>
<body>
<h1>STUDENT ADMISSION FROM FOR ENGINEERING COURSES</h1>
<form action="/FirstSpringMVCPro/submitAdmissionForm.html" method="post">
<p>
Student's Name : <input type="text" name="studentName" />
</p>
<p>
Student's Hobby : <input type="text" name="studentHobby" />
</p>
<input type="submit" value="Submit this form by clicking here"/>
</form>
</body>
</html>
3. 在WEB-INF目录下新建表单提交成功后返回的页面AdmissionSuccess.jsp
<html>
<body>
<h1>Congratulations!! the Engineering college has processed your Application form successfully</h1>
<h2>${msg}</h2>
</body>
</html>
4. 用tomcat运行项目，在浏览器输入http://localhost:8080/FirstSpringMVCPro/admissionForm.html
输入内容后，点击提交按钮
