Question

我正在研究Eclipse / Spring / Maven项目。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"

我的applicationContext.xml如下所示：

我mvn install然后mvn package。我在项目的目标目录中得到springexample-0.0.1-SNAPSHOT.jar的输出。然后我输入命令java - jar springexample-0.0.1-SNAPSHOT.jar并得到以下错误：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Config
uration problem: Unable to locate Spring NamespaceHandler for XML schema namespa
ce [http://www.springframework.org/schema/tx]
Offending resource: class path resource [applicationContext.xml]

通过互联网上的类似问题，我发现了两个可能的错误来源：

未指定用于命名空间处理的spring库（spring-tx） - 已完成（包含在依赖项中） 2.在maven程序集插件的资源中没有指定applicationContext.xml - 已完成（插件配置中包含的资源标记）。

之后，我不知道会出现什么问题。任何帮助表示感谢，谢谢。

Answer 1

尝试添加此项，而不是4.0.0.RELEASE：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <version> 3.2.4.RELEASE</version>
</dependency>

然后执行mvn clean install

运行Maven Assembly插件创建的JAR时出错
