SpirngMVC報錯 not declaration can be found for element ‘mvc:annotation-driven‘

錯誤描述：

使用mvc標籤顯示不能識別

<mvc:annotation-driven conversion-service="ConversionService"/>

報錯：

he matching wildcard is strict,but not declaration can be found for element 'mvc:annotation-driven’

錯誤原因：

問題是不能識別"mvc:annotation-driven/"這個標籤，肯定是xml約束檔案引入的問題。修改引入的xml約束，新增約束：

xmlns:mvc="http://www.springframework.org/schema/mvc"
