如何在JBoss中使用JSR的@Inject @BatchProperty和Spring Batch？

Question

我创建了一个简单的ItemReader：

public class SimpleReader extends AbstractItemReader {

    @Inject @BatchProperty
    private String number;

    @Inject
    JobContext jobContext;

    @Override
    public Object readItem() throws Exception {
        // .....
    }
}

当我将此代码部署到JBoss EAP 6时，我得到以下注入错误：

org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies
for type [String] with qualifiers [@BatchProperty] at injection point
[[field] @Inject @BatchProperty private ....SimpleReader.number]

org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies 
for type [JobContext] with qualifiers [@Default] at injection point 
[[field] @Inject ....SimpleWriter.jobContext]

如果我理解正确，当Weld开始注射时，Spring-Batch尚未初始化。如何初始化Spring-Batch，以便这种注入有效？
