java - 找不到元素 'beans' 的声明。

Question

下面是我的 sdnext-servlet.xml 声明。我收到此错误

"Cannot find the declaration of element 'beans'"

即使我在线。我正在使用 Spring 3.0.1。

这是 sdnext-servlet.xml:

<beans xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Answer 1

这是schemaLocation，而不是schemalocation。

修复该错误后，关闭 context:property-placeholder 和其他一些类似元素，而不是让其内容包含换行符。

这是更新后的有效 XML:

<beans xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
