使用嵌入式jetty11和jersey 3创建Rest API时出现问题[重复]

Question

我在尝试将jersey3与jetty11嵌入式服务器连接时遇到麻烦。我的代码是

        ServletContextHandler servletContextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);

        servletContextHandler.setContextPath("/");
        
        ResourceConfig resourceCfg = new ResourceConfig();
        resourceCfg.packages(TestResource.class.getPackage().getName());      
        
        ServletContainer servletContainer = new ServletContainer(resourceCfg);
        
        ServletHolder servletHolder = new ServletHolder(servletContainer);
        servletContextHandler.addServlet(servletHolder, "/api/*");
        
        this.setHandler(servletContextHandler);

这段代码正好抛出了一个错误

但是，添加this.setHandler（new HandlerList（））不会导致错误。我想这是因为. setHandler方法覆盖了其他处理程序。我仍然不知道导致错误的原因。请帮助！

您没有运行Jersey 3所需的所有依赖项。

你似乎错过了组织。玻璃鱼。运动衫内部的注射InjectionManagerFactory类。

在以下maven坐标中发现...

https://search.maven.org/search?q=fc:org.glassfish.jersey.internal.inject.InjectionManagerFactory

查看过去的答案，以帮助确定哪个工件适合您的需求...

• Jersey已停止使用InjectionManagerFactory，但未找到
• HTTP状态500-Servlet。(init)

顺便说一句，你可以在启动时让Servlet初始化，所以你不需要发送请求来触发这个设置问题。

ServletHolder servletHolder = new ServletHolder(servletContainer);
servletHolder.setInitOrder(1); // <-- this line
servletContextHandler.addServlet(servletHolder, "/api/*");
