无法找到Spring命名空间的Spring NamespaceHandler spring-batch

我必须在循环中运行Spring批处理作业。无法找到Spring命名空间的Spring NamespaceHandler spring-batch

所以我的主类是如下：

package com.mypackage.batch; 

public class myApp { 
public static void main(String[] args) { 

    String[] springConfig = {"spring/batch/jobs/myJob.xml"}; 

    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(springConfig); 

    JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher"); 
    Job job = (Job) context.getBean("myJob");  

    // read the file containing accountIds 
    try (BufferedReader br = new BufferedReader(new FileReader(args[0]))) { 
     String account; 
     while ((account = br.readLine()) != null) { 

      JobParameters param = new JobParametersBuilder().addString("someParam", someParam).toJobParameters(); 
      JobExecution execution = jobLauncher.run(job, param); 
      System.out.println("Exit Status : " + execution.getStatus()); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

    context.close(); 
} 
}

这在Eclipse工作完全正常。

现在我想在服务器上运行它。为此我想创建一个可执行的jar。

我创造它下面使用maven组件插件：

<plugin> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <configuration> 
    <archive> 
     <manifest> 
     <mainClass>com.mypackage.batch.myApp</mainClass> 
     </manifest> 
    </archive> 
    <descriptorRefs> 
     <descriptorRef>jar-with-dependencies</descriptorRef> 
    </descriptorRefs> 
    </configuration> 
</plugin>

这将创建一个罐子依赖性说myBatch-jar-with-dependencies.jar

然而，当我运行以下命令：

java -jar myBatch-jar-with-dependencies.jar abc.txt

我收到以下错误：

在Spring Batch的XML级

我的模式定义为：

我在做什么错？

里面的罐子，在'spring.handlers'文件META-INF目录下，你可以检查是否存在spring-batch命名空间处理程序？ – harshavmb

为什么你不使用Spring Boot和Java配置？ –

@MichaelMinella：因为我无法弄清楚如何在循环中运行Spring Batch作业，就像我在上面的示例中那样。 – Nik

在您的命名空间的声明，只是改变： http://www.springframework.org/schema/batch/spring-batch.xsd是： http://www.springframework.org/schema/batch/spring-batch-3.0.xsd，它应该工作的罚款。

否则，您需要将自定义文件spring.schemas烘焙到您的META-INF文件夹中。

在自定义spring.schemas文件你需要沿着此线的东西映射spring-batch.xsd到spring-batch-3.0.xsd：

http\://www.springframework.org/schema/batch/spring-batch.xsd=org/springframework/batch/core/configuration/xml/spring-batch-3.0.xsd
