推荐答案
请在dispatcher-servlet.xml中定义额外的命名空间
Please, define extra namespace in dispatcher-servlet.xml
<beans
...
xmlns:mvc="http://www.springframework.org/schema/mvc"
...
xsi:schemaLocation="
...
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
添加<mvc:annotation-driven/>以启用注释驱动并支持格式化日期等字段.
Add <mvc:annotation-driven/> to enable annotation-driven and support for formatting Date etc. fields.
