我是靠谱客的博主友好滑板，最近开发中收集的这篇文章主要介绍Spring MVC 使用@InitBinder转换数据，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

示例【Spring MVC 使用@InitBinder转换数据】

创建MyConverter

package com.converter;
import java.beans.PropertyEditorSupport;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
//自定义属性编辑器
public class MyConverter extends PropertyEditorSupport{
	// 将传如的字符串数据转换成Date类型
	@Override
	public void setAsText(String text) throws IllegalArgumentException {
		SimpleDateFormat df=new SimpleDateFormat("yyyy-MM-dd");
		try {
			Date date=df.parse(text);
			setValue(date);
		} catch (ParseException e) {
			e.printStackTrace();
		}
	}	
}

创建UserController

package com.controller;
import java.util.Date;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

import com.converter.MyConverter;
import com.po.User;
@Controller
public class UserController {
	// 在控制器初始化时注册属性编辑器
		 @InitBinder
		  public void initBinder(WebDataBinder binder){
			// 注册自定义编辑器
			binder.registerCustomEditor(Date.class, new MyConverter());
		  }
	@RequestMapping("/register")
	public String register(@ModelAttribute User user,Model model) {
		System.out.println(user);
		model.addAttribute("user", user);
		return "success";
	}
}

配置springmvc-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
<!-- 使用注解驱动 -->
<mvc:annotation-driven/>
<!-- 定义扫描的包 -->
<context:component-scan base-package="com.*" />
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value=""></property>
	<property name="suffix" value=".jsp" />
</bean>
</beans>
