场景：spring mvc中jsp页面向后台传入的数据类型都是String，这里将String转换成Date对象

1.表单页面与显示效果：registerForm.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>Register</title></head><body><h3>Register Page</h3><form action="register" method="post">    <table>        <tr>            <td><label>Login Name:</label></td>            <td><input type="text" id="loginname" name="loginname"></td>        </tr>        <tr>            <td><label>Birthday:</label></td>            <td><input type="text" id="birthday" name="birthday"></td>        </tr>        <tr>            <td><input type="submit" value="Register"></td>        </tr>    </table></form></body></html>

2.成功页面：success.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>Success</title></head><body><h3>You are success</h3></body></html>

3.控制器：UserController.java

4.类型转换器：StringToDateConverter.java

5.spring mvc配置文件添加转换器

<!-- 装载自定义的类型转换器 -->    <mvc:annotation-driven conversion-service="conversionService"/>    <!-- 自定义的类型转换器 -->    <bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">        <property name="converters">            <list>                <bean class="com.demo.converter.StringToDateConverter" p:datePattern="yyyy-MM-dd"></bean>            </list>        </property>    </bean>
