Spring MVC文本域

  1. 创建一个名称为 TextArea 的动态WEB项目。
  2. 在 com.yiibai.springmvc 包下创建两个Java类User，UserController
  3. 在jsp子文件夹下创建两个视图文件：user.jsp，userlist.jsp

**User.java **

package com.yiibai.springmvc;

public class User {
    
    

   private String username;
   private String password;
   private String address;

   public String getUsername() {
    
    
      return username;
   }
   public void setUsername(String username) {
    
    
      this.username = username;
   }

   public String getPassword() {
    
    
      return password;
   }
   public void setPassword(String password) {
    
    
      this.password = password;
   }
   public String getAddress() {
    
    
      return address;
   }
   public void setAddress(String address) {
    
    
      this.address = address;
   }
}

UserController.java

package com.yiibai.springmvc;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.ui.ModelMap;

@Controller
public class UserController {
    
    

   @RequestMapping(value = "/user", method = RequestMethod.GET)
   public ModelAndView user() {
    
    
      return new ModelAndView("user", "command", new User());
   }

   @RequestMapping(value = "/addUser", method = RequestMethod.POST)
   public String addUser(@ModelAttribute("SpringWeb")User user, 
      ModelMap model) {
    
    
      model.addAttribute("username", user.getUsername());
      model.addAttribute("password", user.getPassword());
      model.addAttribute("address", user.getAddress());

      return "userlist";
   }
}
  1. 第一个服务方法user(),已经在ModelAndView对象中传递了一个名称为“command”的空User对象，因为如果在JSP文件中使用form:form标签，spring框架需要一个名称为“command”的对象。 所以当调用user()方法时，它返回user.jsp视图。
  2. 第二个服务方法addUser()将根据URL => TextArea/addUser 上的POST方法请求时调用。根据提交的信息准备模型对象。 最后从服务方法返回“userlist”视图，这将呈现userlist.jsp视图。

user.jsp 的代码

  1. 第一个服务方法user()，我们已经在ModelAndView对象中传递了一个名称为“command”的空User对象，因为如果在JSP文件中使用form:form标签，spring框架需要一个名称为“command”的对象。 所以当调用user()方法时，它返回user.jsp视图。
  2. 第二个服务方法addUser()将根据URL => RadioButtons/addUser 上的POST方法请求时调用。根据提交的信息准备模型对象。 最后从服务方法返回“userlist”视图，这将呈现userlist.jsp视图
