Seam Framework中的非法状态异常

标签： java seam

我有这个简单的课程：

    public class LuceneUtil{

    private final EntityManager entityManager;

public LuceneUtil() {
        entityManager = (EntityManager) Component.getInstance("entityManager");
    }

//other code
}

如果我“正常”使用这个类（我的意思是部署等）一切都很好。 但是，如果我尝试从我的测试类中使用它，当它尝试加载entityManager时，它会给出：

  

java.lang.IllegalStateException：没有活动的应用程序上下文

有没有人有任何想法：为什么？

如果没有正确的Seam应用程序上下文设置，则无法在测试用例中使用Seam组件。这意味着，您必须模拟部署Seam框架。通常，您可以通过使用Seam的测试框架并在运行测试套件时在类路径中使用嵌入式JBoss来实现这一点。如果按以下方式使用组件，则会获得有效的应用程序上下文：

public class LuceneUtilTest extends SeamTest {

    @Test
    public void initComponentTest() throws Exception {
        new ComponentTest() {
            @Override
            protected void testComponents() throws Exception {
                LuceneUtil luceneUtilInstance = (LuceneUtil) Component.getInstance(LuceneUtil.class);
                // ...
            }
        }.run();
    }
}

在ComponentTest内，Seam会在执行测试用例期间注意您有正在运行的应用程序上下文。有关详细信息，请参阅Testing Seam applications。
