SpringMVC-时间类型转换

在上一篇SpringMVC的提交表单中，我们使用的日期为String型，可以将日期转换为Date型，然后使用initBinder函数进行显示，具体代码如下：

（1）首先更改User.java的birthday为Date型

package com.zk.domain;

import java.util.Date;

public class User {
	private Integer id;
	private String name;
	private String age;
	private Date birthday;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	public Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}
}

（2）其次，在CommandController.java中添加initBinder方法。

package com.zk.UserController;

import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.validation.BindException;
import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

import com.zk.domain.User;

//从页面接受参数，封装javaBean的User对象
public class CommandController extends AbstractCommandController{
	//指定把参数封装到那个对象。
	public CommandController(){
		this.setCommandClass(User.class);
	}
	@Override
	protected ModelAndView handle(HttpServletRequest request,
			HttpServletResponse response, Object command, BindException errors)
			throws Exception {
		// TODO Auto-generated method stub
		//值被封装命令对象
		User user=(User) command;

		ModelAndView mv=new ModelAndView();
		//设置models
		mv.addObject("user",user);
		//指定返回视图界面
		mv.setViewName("index");

		return mv;
	}
	@Override
	protected void initBinder(HttpServletRequest request,
			ServletRequestDataBinder binder) throws Exception {
		// TODO Auto-generated method stub
		String birthday=request.getParameter("birthday");
		if(birthday.contains("/")){
		binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy/MM/dd"),true));
		}else{
		binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"),true));
		}
	}

}

　　其余与SpringMVC提交表单的代码相同，运行后得到如下运行结果：
