未检测到Hadoop spring命名空间

Question

我正在使用Maven-jar插件创建一个jar，并在执行时出现以下错误：

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: 
Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace 
[http://www.springframework.org/schema/hadoop]
Offending resource: class path resource [applicationContext.xml]

我正在使用Hadoop 1.2.1版本。

我的applicationContext.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:hdp="http://www.springframework.org/schema/hadoop"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/hadoop http://www.springframework.org/schema/hadoop/spring-hadoop.xsd">

<context:property-placeholder location="hadoop.properties" />
......
</beans>

我的pom.xml看起来像这样：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

我已将jar添加到我的src / main / resources文件夹中。

我无法确定问题所在。请帮助。

尝试在您的pom.xml中添加AppendingTransformers。
