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:
