我有一个简单的测试应用程序，我将它部署到 GlassFish（只有一个资源注入了一个简单的类）。在 GlassFish 上，一切正常（记录 FINE 时的例外情况除外，请参见此处）。我可以成功调用资源并且 Weld CDI 正在进行注入。
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，似乎 HK2 正在尝试提供注入，然后导致 UnsatisfiedDependencyException。
我可以定义一个将绑定 InjectMe 类的 AbtractBinder，以便 HK2 知道它。然后注入工作正常。但是 Weld CDI 应该将类注入 Jersey 资源，而不是 HK2。
引导是通过创建自定义 JUnit 运行器 (WeldJUnit4Runner) 和@RunWith(WeldJUnit4Runner.class)注释来完成的，示例见此处：http ://blog.rocketscience.io/dependency-injection-with-cdi-in-java-se/
Weld CDI 为 Java SE 环境成功引导，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 类是由 Weld 引导发现的：
2014-07-16 10:41:12,730 [DEBUG] org.jboss.weld.Bootstrap - WELD-000106: Bean: Managed Bean [class com.test.rest.InjectMe] with qualifiers [@Any @Default]
问题：为什么 HK2 在 Java SE 中运行时尝试注入 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
我已经通过为 Netbeans“测试文件”操作定义它来做到这一点。在属性文件中，必须定义以下标志：
org.glassfish.jersey.level=FINEST
当我昨天进行测试时，有一段时间这个确切的设置确实有效，没有给我那些例外。我认为，静态初始化存在问题，HK2 有时会先初始化，我认为这会导致此错误。
资源：
package com.test.rest;
import javax.inject.Inject;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Path("rest/import")
public class DataImport {
private final Logger logger = LoggerFactory.getLogger(getClass());
@Inject
private InjectMe me;
public DataImport() {}
@GET
@Produces("text/html")
public String getHtml() {
logger.debug("getHtml of DataImport called!");
return "<html><body><h1>IMPORT Resource: " + me.field + " </body></h1></html>";
}
}
应用配置：
package com.test.rest;
import java.util.logging.Logger;
import org.glassfish.jersey.filter.LoggingFilter;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.filter.RolesAllowedDynamicFeature;
@javax.ws.rs.ApplicationPath("/rest")
public class ApplicationConfig extends ResourceConfig {
public ApplicationConfig() {
register(DataImport.class);
register(RolesAllowedDynamicFeature.class);
//tracing/logging
property("jersey.config.server.tracing.type", "ALL"); //enable tracing support, logs requests
registerInstances(new LoggingFilter(Logger.getLogger(ApplicationConfig.class.getName()), true));
}
}
