那些遇到过的问题

注入 Jersey 资源，HK2 在 Java SE 中运行时进行注入而不是 Weld -> 依赖关系不满足

use*_*334 5 junit jersey-2.0 weld2 hk2

我有一个简单的测试应用程序，我将其部署到 GlassFish（只有一个资源注入了一个简单的类）。在 GlassFish 上，一切工作正常（除了记录 FINE 时的例外情况，请参阅此处）。我可以成功调用资源，并且 Weld CDI 正在执行注入。

现在，当我在 Java SE 中启动应用程序以使用 JUnit 进行单元测试时，HK2 似乎正在尝试提供注入，这会导致 UnsatisfiedDependencyException。

我可以定义一个 AbtractBinder 来绑定 InjectMe 类，以便 HK2 知道它。然后注射就可以正常工作了。但 Weld CDI 应该将该类注入 Jersey 资源，而不是 HK2。

引导是通过创建自定义 JUnit 运行程序 (WeldJUnit4Runner) 和@RunWith(WeldJUnit4Runner.class)注释来完成的，有关示例，请参见此处：http ://blog.rocketscience.io/dependency-injection-with-cdi-in-java-se/

Weld CDI 已成功引导到 Java SE 环境，我可以成功地将 InjectMe 类注入到实际的 JUnit 测试类中，而不是注入到 Jersey 资源中。InjectMe 类是通过 Weld 引导发现的：

问题：在 Java SE 中运行时，为什么 HK2 尝试注入 InjectMe 类而不是 Weld？

编辑： 我创建了一个 Netbeans 项目，因此您可以轻松地重现此测试： simple-service.zip。不要忘记将 java 日志记录的属性设置为logging.properties 文件：

java.util.logging.config.file=C:\glassfish4\glassfish\domains\domain1\config\logging.properties

我通过为 Netbeans“测试文件”操作定义它来完成此操作。在属性文件中，必须定义以下标志：

org.glassfish.jersey.level=FINEST

当我昨天测试时，有一段时间这个确切的设置确实有效，没有给我这些例外。我认为静态初始化存在问题，HK2 有时首先初始化，我认为这会导致此错误。
