运行批处理时无法创建工件

Question

尝试运行批处理时出现此错误：

16：05：35,807警告[org.jberet]（批处理线程-1）JBERET000001：无法运行批处理org.jberet.job.model.RefArtifact@2dea3d8a：java.lang.IllegalStateException：JBERET000600：无法创建带有以下内容的工件参考名称MyBatchlet。确保存在CDI beans.xml，并且正确配置了batch.xml（如果有）。在org.jberet.runtime.context.JobContextImpl.createArtifact（JobContextImpl.java:185）在org.jberet.runtime.runner.AbstractRunner.createArtifact（AbstractRunner.java:156）在org.jberet.runtime.runner.BatchletRunner.run（BatchletRunner.java:66）在org.jberet.runtime.runner.StepExecutionRunner.runBatchletOrChunk（StepExecutionRunner.java:229）在org.jberet.runtime.runner.StepExecutionRunner.run（StepExecutionRunner.java:147）在org.jberet.runtime.runner.CompositeExecutionRunner.runStep（CompositeExecutionRunner.java:164）在org.jberet.runtime.runner.CompositeExecutionRunner.runFromHeadOrRestartPoint（CompositeExecutionRunner.java:88）在org.jberet.runtime.runner.JobExecutionRunner.run（JobExecutionRunner.java:60）在org.wildfly.extension.batch.jberet.impl.BatchEnvironmentService $ WildFlyBatchEnvironment $ 1.run（BatchEnvironmentService.java:243）在org.wildfly.extension.requestcontroller.RequestController $ QueuedTask $ 1.run（RequestController.java:497）在org.jberet.spi.JobExecutor $ 3.run（JobExecutor.java:161）在org.jberet.spi.JobExecutor $ 1.run（JobExecutor.java:99）在java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1149）在java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:624）在java.lang.Thread.run（Thread.java:748）在org.jboss.threads.JBossThread.run（JBossThread.java:320）原因：java.lang.IllegalStateException：JBERET000600：无法创建参考名称为MyBatchlet的工件。确保存在CDI beans.xml，并且正确配置了batch.xml（如果有）。在org.jberet.creation.ArtifactFactoryWrapper.getClassFromBatchXmlOrClassLoader（ArtifactFactoryWrapper.java:65）在org.jberet.creation.ArtifactFactoryWrapper.create（ArtifactFactoryWrapper.java:41）在org.jberet.runtime.context.JobContextImpl.createArtifact（JobContextImpl.java:183）...另外15个原因：java.lang.ClassNotFoundException：[服务模块加载器中的[module“ deployment.idkwebapp.war：main”中的] MyBatchlet。在org.jboss.modules.ModuleClassLoader.findClass（ModuleClassLoader.java:198）在org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked（ConcurrentClassLoader.java:363）在org.jboss.modules.ConcurrentClassLoader.performLoadClass（ConcurrentClassLoader.java:351）在org.jboss.modules.ConcurrentClassLoader.loadClass（ConcurrentClassLoader.java:93）在org.jberet.creation.ArtifactFactoryWrapper.getClassFromBatchXmlOrClassLoader（ArtifactFactoryWrapper.java:63）... 17更多

我创建了beans.xml，但仍然无法正常工作...

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
</beans>

这里是批处理：

package br.com.idk;

import javax.batch.runtime.context.JobContext;
import javax.batch.runtime.context.StepContext;
import javax.inject.Inject;

public class MyBatchlet {

	 @Inject JobContext jobContext;
	 @Inject StepContext stepContext;

	public String process() throws Exception {
		
	    long executionId = jobContext.getExecutionId();
		
	    System.out.println("I'm a cool batchlet!!!!!!!!!!!!!!!");
	    
		return null;
	}

	public void stop() throws Exception {
		// TODO Auto-generated method stub
		
	}	
	
	
}

我在这里叫它：

package br.com.idk;

import java.util.Properties;

import javax.batch.operations.JobOperator;
import javax.batch.runtime.BatchRuntime;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("/hello")
public class Resource {
	
	@GET
	@Path("testBatch")
	public Long testBatch() {
		JobOperator jobOperator = BatchRuntime.getJobOperator();
        Properties props = new Properties();
        props.setProperty("name", "Dude");
        
        return jobOperator.start("simple-batchlet-job", props);
	}
}

这是工作的XML：

<?xml version="1.0" encoding="UTF-8"?>
<job id="simple-batchlet-job" xmlns="http://xmlns.jcp.org/xml/ns/javaee">
    <step id="myBatchlet">
        <batchlet ref="MyBatchlet"/>
    </step>
</job>

像这样用bean-discovery-mode =“ all”更改您的beans.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans
        xmlns="http://xmlns.jcp.org/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                      http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
        bean-discovery-mode="all">
</beans>
