使用 Maven 配置 Spring Batch。使用的JDK：1.6，Spring Batch 2.1.8.RELEASE；春季版本 3.0.5.RELEASE。获取运行时异常如下：

D:\SpringProject\SpringTry\target>java -jar SpringTry-1.0-SNAPSHOT.jar jobs/helloWorld.xml helloWorldJob

有关如何解决此问题的任何建议。还注意到每次都会下载 Spring 2.5.6，以及提到的版本 3.0.5

我的清单看起来像：

您很可能是：

  • 只需使用版本低于 2.0 的 spring-batch-core jar 版本（Maven 依赖项）。Schema 命名适用于 2.0 及更高版本。如果是这种情况，请更新您的依赖项

或者

  • 您在项目的 pom.xml 中有正确（高于 2.0）版本的 spring-batch-core，但您也有一个传递依赖项，它将早期版本的 spring-batch-core 带入您的项目。如果是这种情况，请尝试以下操作：

    mvn 依赖：tree -Dverbose -Dincludes=org.springframework.batch

这将列出所有引入他们自己版本的 spring-batch 依赖项的依赖项。在 spring-batch-core 上为这些依赖项添加一个排除条目，如下所示：

<dependency>
          <groupId>whatever.group</groupId>
          <artifactId>whateverArtifact</artifactId>
          <version>1.0</version>
          <exclusions>
            <exclusion>
                <groupId>org.springframework.batch</groupId>
                <artifactId>spring-batch-core</artifactId>
            </exclusion>
          </exclusions>
        </dependency>

我的问题通过添加 maven-shade-plugin 得到解决，详见： https ://stackoverflow.com/a/8574629/1419116
