一個一般的表單。
表單的代碼如下：
[java] view plaincopy
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
1、直接把表單的參數寫在Controller相應的辦法的號碼大全形參中
[java] view plaincopy
@RequestMapping("/addUser1")
public String addUser1(String userName,String password) {
System.out.println("userName is:"+userName);
System.out.println("password is:"+password);
return "/user/success";
}
2、經過HttpServletRequest接納關鍵詞挖掘工具
[java] view plaincopy
@RequestMapping("/addUser2")
public String addUser2(HttpServletRequest request) {
String userName = request.getParameter("userName");
String password = request.getParameter("password");
System.out.println("userName is:"+userName);
System.out.println("password is:"+password);
return "/user/success";
}
3、經過一個bean來接納
1）樹立一個和表單中參數對應的bean
[java] view plaincopy
public class User {
private String userName;
private String password;
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;
}
}
2）用這個bean來封裝接納的參數
[java] view plaincopy
@RequestMapping("/addUser3")
public String addUser3(User user) {
System.out.println("userName is:"+user.getUserName());
System.out.println("password is:"+user.getPassword());
return "/user/success";
}
4、經過json數據接納
[java] view plaincopy
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
仍然能夠運用bean來接納json數據
[java] view plaincopy
@RequestMapping("/addUser4")
public String addUser4(User user) {
System.out.println("userName is:"+user.getUserName());
System.out.println("password is:"+user.getPassword());
return "/user/success";

5、運用jQuery的serializeArray() 辦法序列化表單元素
假如表單元素很多，手藝拼裝成json數據十分費事，能夠運用jQuery供給的serializeArray()辦法序列化表單元素，回來json數據結構數據。
[java] view plaincopy
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
仍然能夠運用bean來接納json數據：
[java] view plaincopy
@RequestMapping("/addUser5")
public String addUser5(User user) {
System.out.println("userName is:"+user.getUserName());
System.out.println("password is:"+user.getPassword());
return "/user/success";
}
