java.lang.NoClassDefFoundError:org/glassfish/jersey/server/spi/Container

我正在尝试设置Jersey 2 servlet应用程序.目标是仅将一些URL映射到Jersey REST API,而其他URL则提供静态内容.

我mvn compile war:war用来生成战争并部署它.部署工件时会发生以下错误:

当我查看WAR文件时,WEB-INF/lib中充满了JAR文件.为什么Jetty不能部署WAR文件？

这三个依赖

    org.glassfish.jersey.containers
    jersey-container-servlet
    2.22.1
    provided


    org.glassfish.jersey.core
    jersey-server
    2.22.1
    provided


    org.glassfish.jersey.core
    jersey-client
    2.22.1
    provided

已经被这种依赖所吸引了

    org.glassfish.jersey.containers
    jersey-container-jetty-servlet
    2.22.1

但是当你声明它们时,你会覆盖它将它们拉入的事实.你将它们声明为 provided

provided

这意味着您说服务器具有这些依赖关系,但它没有.如果你查看WEB-INF/lib,你会看到那三个不存在.这就是错误的原因.最好的办法就是摆脱这三个,因为它们已被拉入.

实际上你可以摆脱除最后一个之外的所有东西,因为它会引入你声明的所有东西.
