springmvc的日期转换器和编码过滤器

1）  在默认情况下，springmvc不能将String类型转成Date类型，必须自定义类型转换器

public class AdminAction extends AbstractCommandController{
@Override
protected void initBinder(HttpServletRequest request,ServletRequestDataBinder binder) throws Exception {
binder.registerCustomEditor(Date.class,new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"),true));
}

2）spring提供的，专用于解决POST提交中文乱码问题，需要在web.xml文件中配置

<!-- 编码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
