找不到元素'beans'的聲明。

Question

以下是我的sdnext-servlet.xml聲明。 我收到此錯誤

“找不到元素'beans'的聲明”

即使我在線。 我正在使用Spring 3.0.1。

這是sdnext-servlet.xml：

<beans xmlns:context="http://www.springframework.org/schema/context"

Answer 1

它是schemaLocation而不是schemalocation 。

解決該錯誤后，請關閉context:property-placeholder和其他一些類似元素，而不要讓其內容包含換行符。

這是您更新的有效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"
