問題描述

Maven版本：pache-maven-3.2.5
Java版本（運行）：1.7.0_75
jdk版本：1.6.0_65

我使用Maven包生成jar文件

然后我用java -jar GAImage-1.0-SNAPSHOT-jar-with-dependencies.jar運行它，它會拋出異常

無法找到XML模式命名空間的Spring NamespaceHandler [ http://www.springframework.org/schema/tx]

我不知道為什么，我的Java IDE中的程序運行正常（IntellIj 14）

3 個解決方案

作為建議在這里 ，它可能是由依賴性沖突，可以通過使用maven的樹蔭插件，以確保META-INF文件被正確設置來解決造成的。 

<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
  <resource>META-INF/spring.handlers</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
  <resource>META-INF/spring.schemas</resource>
</transformer>

您可以在此處http://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html了解更多有關Shade插件的信息。

另外，您可以使用maven exec插件運行jar： 

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.2.1</version>
            <configuration>
                <mainClass>com.example.Main</mainClass>
            </configuration>
        </plugin>
    </plugins>
</build>

運行方式： 

mvn exec:java

問題可能是依賴沖突。 創建XXX-jar-with-dependencies.jar時，jar中僅包含任何重復的單個文件。 有時這可能會導致版本沖突和配置文件出現問題。 Intellij似乎很擅長避免這些問題。

最好的解決方法是使用Maven陰影插件（ http://maven.apache.org/plugins/maven-shade-plugin ）創建依賴項jar。 插件的配置可能相當復雜，但確實會向您提供有關其功能的反饋。 下面是一個示例配置，顯示了如何生成相同的命名依賴項jar。 您將需要確定需要對哪些文件進行哪些轉換才能使其工作。 您可能還需要將排除項添加到依賴項中，但是陰影也表示何時可能需要這些排除項。
