ClassNotFoundExc0019： ClientBuilder泽西2.25.1 Tomcat 9.0

Question

我已经为此挣扎了几天，现在无法找到一个合适的解决方案。我读过类似的问题，但没有一个解决方案是充分的。

我的规格：Tomcat 9.0.0。M22，泽西2.25.1，马文4.0.0，智能2017.1.4。

让我绞尽脑汁的是，我可以在一个公共静态void main（）{}函数中毫无障碍地运行代码。我想这意味着我的jar被Maven正确地包含了进去。但是，当我试图通过ServletContextListener在Tomcat9.0上运行它时，它会在ClientBuilder上冻结。newBuilder（）。寄存器（SseFeature.class）。build（）调用并抛出此错误。

我的监听器代码：

import org.glassfish.jersey.media.sse.SseFeature;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

public class EventListener implements ServletContextListener {
    public void contextInitialized(ServletContextEvent sce) {
        System.out.println("I got in here");
        Client client1 = ClientBuilder.newBuilder().register(SseFeature.class).build();
        System.out.println("I never make it here");
    }
    public void contextDestroyed(ServletContextEvent sce) {}
}

解决方案1：我试着把*jersey-client-2.25。1.jar，*jersey-media-sse-2.25。1.jar和*番石榴-22.0。jar在我的WEB-INF/libs目录中<解决方案2：我正在使用Jersey 2.25。1.
解决方案3：这一个实际上并不相关，因为他们有一个不同的异常
解决方案4：更改pom。xml没有什么区别<解决方案5：我试着创建一个META-INF目录并添加所告知的内容，但仍然没有任何结果
解决方案6：尝试添加指定的依赖项\u无效，因此我立即将其删除。

Answer 1

我没有向WEB-INF/libs目录添加足够的库。我必须进入项目结构-

附言：我应该删除这个问题吗？

Answer 2

您必须使打包类型为war，将JAR包含在依赖项中，运行mvn内置终端，导航到目标文件夹，您将在其中包含war文件所有内容。
