我正在使用 JBoss 实现JBeret在 Java SE 下构建JSR352（Java 平台的批处理应用程序）演示。我想为这项工作运行集成测试。在这个批处理作业中，有 3 个组件：
io.mincong.batch.MyItemReaderio.mincong.batch.MyItemProcessorio.mincong.batch.MyItemWriter
它们都被命名为带有注释的bean @Named，例如
@Named
public class MyItemProcessor implements ItemProcessor {
// ...
}
多亏了这个注释，我可以使用作业类，而无需io.mincong.batch在我的作业文件中输入包名前缀myJob.xml。这在 Java EE 容器中可以正常工作，例如 WildFly 10。但是，在 Java SE 中，它不再工作了，我必须添加包前缀。这里的工作 xml myJob.xml：
<?xml version="1.0" encoding="UTF-8"?>
<job id="myJob" 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/jobXML_1_0.xsd"
version="1.0">
<step id="printID">
<chunk item-count="5">
<!-- This works :
<reader ref="io.mincong.batch.MyItemReader"/>
<processor ref="io.mincong.batch.MyItemProcessor"/>
<writer ref="io.mincong.batch.MyItemWriter"/> -->
<!-- This doesn't work -->
<reader ref="myItemReader"/>
<processor ref="myItemProcessor"/>
<writer ref="myItemWriter"/>
</chunk>
</step>
</job>
你可以在附件中找到 2 mvn install log，有和没有包前缀。换句话说，使用和不使用@Named。为什么会发生此错误？我是否缺少一些依赖项？任何想法 ？
你也可以在下面看到我的 pom.xml。附加信息：
- JBERET：设置 JBeret
- JBERET：最小的应用程序依赖
- JBERET：Java SE 批处理应用程序的附加依赖项
- JBERET：GitHub 上的 jberet/jsr352/test-apps
