1、直接把表單的參數(shù)寫在Controller相應(yīng)的方法的形參中
|
1
2
3
4
5
6
|
@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、通過HttpServletRequest接收
|

|
@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、通過一個bean來接收
1）建立一個和表單中參數(shù)對應(yīng)的bean
|
1
2
|
public class User { private String userName; private String password; public String getUserName() { return userName; } //getter，setter方法。。. } |
2）用這個bean來封裝接收的參數(shù)
|
1
2
3
4
5
6
|
@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、通過json數(shù)據(jù)接收

依然可以使用bean來接收json數(shù)據(jù)
|

@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、使用jQuery的serializeArray() 方法序列化表單元素
如果表單元素很多，手工拼裝成json數(shù)據(jù)非常麻煩，可以使用jQuery提供的serializeArray()方法序列化表單元素，返回json數(shù)據(jù)結(jié)構(gòu)數(shù)據(jù)。
