无法将 HttpServletRequest 注入 ContainerRequestFilter with Javal 11、Jetty 和 Jersey



我正在更新Java 8 web服务以在Java 11上运行。我对Java不太熟悉，我对c#。net环境比较熟悉。我已经阅读了几十篇关于这个问题的文章和问题，我非常确信我的代码应该可以工作，但是我的项目设置是错误的。

我的原始项目只有一个Eclipse项目文件，我添加了Maven，并重新组织了我的项目，以便我可以构建一个爆炸的WAR并从那里进行调试。目前，有问题的代码如下:

@Provider
@Priority(Priorities.AUTHENTICATION)
public class SecurityFilter implements ContainerRequestFilter {
@Inject
private jakarta.inject.Provider<HttpServletRequest> requestProvider;

@Override
public void filter(ContainerRequestContext filterContext) throws IOException {
var servletRequest = requestProvider.get();
}
}
这给了我一个错误，如: 
jakarta.servlet.ServletException: jakarta.servlet.ServletException: A MultiException has 2 exceptions.  They are:
1. java.lang.IllegalArgumentException: org.glassfish.hk2.api.ProxyCtl referenced from a method is not visible from class loader

我的原始代码是这样的:

@Provider
@Priority(Priorities.AUTHENTICATION)
public class SecurityFilter implements ContainerRequestFilter {
@Context
private HttpServletRequest servletRequest;

@Override
public void filter(ContainerRequestContext filterContext) throws IOException {
}
}

给出了同样的两个异常加上另外一个4。@Inject方法在动作被调用时导致异常，@Context方法在服务器启动时导致异常，但无论哪种情况，httpServletRequest都不能由DI容器/作用域提供。

我不是100%确定所有的位是如何一起工作的，但如果我有正确的，应用程序使用Jetty 11.0.6自托管web服务器，与Jersey 3.0.2容器，运行雅加达平台9.1.0 - Servlet API V5.0，和雅加达JAXB web服务。我想我遗漏了一个依赖项，但我还不能确定它是什么。以下是我的POM和Web.xml文件:

我真的希望有人知道我错过了什么。仅供参考-我已经在我的POM中留下了所有当前依赖项，而不仅仅是那些我认为相关的依赖项，因为可能是我有多个依赖项导致了这个问题。

服务器启动代码更难清理，但如果有必要，我可以发布它-主要部分是WebAppContext，它似乎可以读取servlet -如果我不使用@Context, servlet也会响应，它们只是因为空引用或坏的DI设置而崩溃。

感谢您的帮助。

——更新

我一直在切换一些Maven依赖项。我很确定我有Jetty, Jakarta, JAXB和Jersey的基本依赖关系，但我仍然得到@Context/@Inject的问题。我很需要这件org.glassfish.球衣。inject:jersey-hk2包，因为如果我把它去掉，我会得到一个错误:java.lang。。如果我再加上雅加达。

所以基本上我有两个注入包，@Context/@Inject对其中一个或两个都不起作用。我想知道雅加达9是否需要一些设置代码，但我没有在任何示例中看到任何设置代码。

我的pom依赖现在看起来像这样-仍然不高兴(我还忽略了应用程序深度):

最新更新:

所以我切换回OpenJDK 8，期待项目运行，事实证明它不起作用。在将jar与原始项目进行比较时，我注意到我的新程序具有不同的jar。进一步看，现有的项目没有HK2文件，但这些文件在jersey-common包中发货。

有没有人知道如何在项目中有泽西没有航运HK2罐，因为HttpServletRequest的注入工作没有他们?

标记

所以这个问题很难解决，因为元素在Jetty, Jakarta和Jersey之间的交互方式在运行时都在幕后，也就是说，程序成功编译了任何数量的不工作的排列。

无论如何，经过大约7天的实验，允许注入HttpServletRequest工作的包的集合如下:

我在Java 8中编译我的原始项目时发现了这个问题(就像我添加Maven之前一样)，我发现我的非Maven项目没有输出3个hk2相关的库，hk2-api-2.2.0-b21.jar, hk2-locator-2.2.0-b21.jar, hk2-utils-2.2.0-b21.jar。删除这些文件可以使程序正常运行。

然后我尝试使用依赖排除，但即使我最终使用相同的库，程序也无法工作。现在我不太确定这是如何工作的，但我记得读到依赖关系可以作用域为"提供"，这就是说(如果我理解正确的话)-所需的类实现已经存在于您已经拥有的一些库中(如JRE或其他依赖)，因此您不必再次包含库。

再次-我不明白为什么这工作，但它绝对必须这样设置。我真的希望这能让某人少活几天!
