在不 运行 活跃的 Jersey 错误范围的代码中检测到 HK2 故障
HK2 failure has been detected in a code that does not run in an active Jersey Error scope
目前我正在开发一个基于球衣的 RESTful 应用程序并且想在我的资源中使用 DPI。
（注：jersey的版本是2.23.1，servlet容器是tomcat8.5.3。）
因此我遵循了 jersey 文档中的教程 Chapter 23. Custom Injection and Lifecycle Management 并创建了一个资源、一个工厂并将工厂绑定到 class，如下所示：
资源：
@Path("/{project}/catalogs")
public class ProjectsResource {
@Inject
Project project;
...
}
工厂：
public class ProjectFactory extends Factory<Project> {
private final Cache cache = cache.getInstance();
@PathParam("project")
private String project;
private HttpServletRequest request;
@Inject
public ProjectFactory(HttpServletRequest request) {
this.request = request;
}
@Override
public Project provide() {
return cache.get(project, Project.class);
}
@Override
public void dispose(Project instance) {}
}
我还有一个功能，它注册了一个 AbstractBinder，它将我的 ProjectFactory 绑定到我的项目 class。
@Provider
public class ProjectFeature implements Feature {
@Override
public boolean configure(FeatureContext context) {
context.register(new AbstractBinder() {
@Override
protected void configure() {
bindFactory(ProjectFactory.class)
.to(Project.class)
.proxy(false)
.proxyForSameScope(true)
.in(RequestScoped.class);
});
return true;
}
}
实际问题是，当我调用我的资源时，一切都很好，我可以访问我的项目实例，但在我的 tomcat catalina 日志中，我得到以下堆栈跟踪：

有什么办法可以解决这个警告吗？
我能够通过注入 Factory 而不是直接注入 class 来解决这个错误。我还测试了 HttpServletRequest 注入，它也能正常工作。然而，没有 @PathParam 或任何其他智能注释对我有用，所以很可能你必须解决它们的使用问题。
我的旧代码：
@Inject
public void setContext(ContainerRequestContext context) {
this.context = context;
}
@Override
public SomeInfo provide() {
return (SomeInfo) context.getProperty(SOME_KEY);
}
我的新密码：
@Inject
public void setContext(Factory<ContainerRequestContext> contextFactory) {
this.contextFactory = contextFactory;
}
@Override
public SomeInfo provide() {
ContainerRequestContext ctx = contextFactory.provide();
try {
return (SomeInfo) ctx.getProperty(SOME_KEY);
} finally {
contextFactory.dispose(ctx);
}
}
当我将我的工厂绑定到我的界面时，我可以通过使用 HK2 的 org.glassfish.hk2.api.PerLookup 注释而不是 Jerseys org.glassfish.jersey.process.internal.RequestScoped 注释 class 来解决这个问题。
import org.glassfish.hk2.api.PerLookup;
@Provider
public class ProjectFeature implements Feature {
@Override
public boolean configure(FeatureContext context) {
context.register(new AbstractBinder() {
@Override
protected void configure() {
bindFactory(ProjectFactory.class)
.to(Project.class)
.proxy(false)
.proxyForSameScope(true)
.in(PerLookup.class);
});
return true;
}
}
您可以检查您在 class 中的某个方法中是否有语法错误，您不能 "import" 使用 Jersey，对我来说就是这种情况。我在一个字符串中有两个未闭合的加号。
目前我正在开发一个基于球衣的 RESTful 应用程序并且想在我的资源中使用 DPI。 （注：jersey的版本是2.23.1，servlet容器是tomcat8.5.3。）

return true;
}
}
实际问题是，当我调用我的资源时，一切都很好，我可以访问我的项目实例，但在我的 tomcat catalina 日志中，我得到以下堆栈跟踪：
