cvc-elt.1：找不到元素“beans”的声明-Spring 4.0.2 [重复]

Question

虽然我尝试了很多方法来解决这个问题，但还没有成功。

我在“dispatcher-servlet.xml”文件中收到此错误“cvc-elt.1: 找不到元素 'beans' 的声明”。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <context:component-scan base-package="com.b2b.controller" />

</beans>

我的 pom.xml 文件是：

谁能看看我的问题。

Answer 1

您为 beans 元素使用了不带前缀的名称，但您已将相关的命名空间绑定到前缀

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

您可能希望使用默认命名空间声明 xmlns="..." 而不是 xmlns:beans="..."，或者替代方法是为元素名称添加前缀

<beans:beans ...>

Answer 2

将xmlns:beans="http://www.springframework.org/schema/beans" 更改为xmlns="http://www.springframework.org/schema/beans"

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns="http://www.springframework.org/schema/beans"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <context:component-scan base-package="com.b2b.controller" />

</beans>
