Converter实现Date类型转换

1.springmvc-config.xml配置

<?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: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-4.3.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-4.3.xsd
       http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <context:annotation-config/>
    <context:component-scan base-package="com.wxy.controller"/>
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    <mvc:annotation-driven conversion-service="conversionService" />
    <bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <bean class="com.wxy.convert.DateConverter" />
            </set>
        </property>
    </bean>
</beans>

2.日期转换类DateConverter.java

 package com.wxy.convert;

 import org.springframework.core.convert.converter.Converter;
 import java.text.ParseException;
 import java.text.SimpleDateFormat;
 import java.util.Date;

 public class DateConverter implements Converter<String,Date> {
     private String datePattern = "yyyy-MM-dd HH:mm:ss";
     @Override
     public Date convert(String source){
         SimpleDateFormat simpleDateFormat = new SimpleDateFormat(datePattern);
         try{
             return simpleDateFormat.parse(source);
         }catch (ParseException e){
             throw new IllegalArgumentException(
                     "无效的日期格式，请使用这种格式："+datePattern
             );
         }
     }
 }

3.日期控制器类DateController

package com.wxy.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Date;
@Controller
public class DateController {
    @RequestMapping("/customDate")
    public String CustomDate(Date date){
        System.out.println("date="+date);
        return "success";
    }
}

目前是不完善版本，只能控制台输出，等完善jsp页面，再修改。
