BaseController处理表单数据绑定问题

一、第一步写个基础控制类

 import java.text.SimpleDateFormat;

 2 import java.util.Date;

 3

 4 import org.springframework.beans.propertyeditors.CustomDateEditor;

 5 import org.springframework.stereotype.Controller;

 6 import org.springframework.web.bind.WebDataBinder;

 7 import org.springframework.web.bind.annotation.InitBinder;

 8

 9 import sun.beans.editors.DoubleEditor;

10 import sun.beans.editors.FloatEditor;

11 import sun.beans.editors.IntEditor;

12 import sun.beans.editors.LongEditor;

13

14 @Controller

15 public class BaseController {

16

17     @InitBinder    

18     public void initBinder(WebDataBinder binder) {    

19

20         binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true));

21         binder.registerCustomEditor(int.class, new IntEditor());

22         binder.registerCustomEditor(long.class, new LongEditor());  

23         binder.registerCustomEditor(double.class, new DoubleEditor());  

24         binder.registerCustomEditor(float.class, new FloatEditor());  

25     }

26     

27     

28 }

二、第二部继承过来

import org.springframework.stereotype.Controller;

 2 import org.springframework.web.bind.annotation.RequestMapping;

 3

 4 import com.kickstarter.entity.User;

 5

 6 @Controller("userController") 继承过来

 7 public class UserController extends BaseController{

 8

 9     @RequestMapping(value="regUser")

10     public String dateTest(User user , double dd){

11         

12         System.out.println( user.toString() );

13         System.out.println( dd );

14         return "index";

15     }

16 }

三、注解方式

import java.util.Date;

 2

 3 import org.springframework.format.annotation.DateTimeFormat;

 4

 5 public class User {

 6

 7     private int userId;

 8     private String userName;

 9     

10     @DateTimeFormat(pattern="yyyy-MM-dd")//这里加注解

11     private Date createDate;

12     

13     public User() {}

14

15     public User(int userId, String userName, Date createDate) {

16         super();

17         this.userId = userId;

18         this.userName = userName;

19         this.createDate = createDate;

20     }

21

22     public User(String userName, Date createDate) {

23         super();

24         this.userName = userName;

25         this.createDate = createDate;

26     }

27

28     public int getUserId() {

29         return userId;

30     }

31

32     public void setUserId(int userId) {

33         this.userId = userId;

34     }

35

36     public String getUserName() {

37         return userName;

38     }

39

40     public void setUserName(String userName) {

41         this.userName = userName;

42     }

43

44     public Date getCreateDate() {

45         return createDate;

46     }

47

48     public void setCreateDate(Date createDate) {

49         this.createDate = createDate;

50     }

51

52     @Override

53     public String toString() {

54         return "User [createDate=" + createDate + ", userId=" + userId

55                 + ", userName=" + userName + "]";

56     }

57 }
