SpringMVC接收页面表单参数
一个一般的表单。
表单的代码如下：
[java] view plaincopy
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
1、直接把表单的参数写在Controller相应的办法的号码大全形参中
[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、经过HttpServletRequest接纳关键词挖掘工具
[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、经过一个bean来接纳
1）树立一个和表单中参数对应的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）用这个bean来封装接纳的参数
[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、经过json数据接纳
[java] view plaincopy
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
仍然能够运用bean来接纳json数据
[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、运用jQuery的serializeArray() 办法序列化表单元素
假如表单元素很多，手艺拼装成json数据十分费事，能够运用jQuery供给的serializeArray()办法序列化表单元素，回来json数据结构数据。
[java] view plaincopy
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
仍然能够运用bean来接纳json数据：
[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";
}
