java - 使用 Maven 和 Jersey 库编译 REST WebService 时遇到问题

标签 java rest web-services maven tomcat

我在 Jersey 编译 Web 服务时遇到问题，我看到了很多关于这个问题的答案，但没有一个对我有帮助。我正在尝试在 tomcat 8.5 上运行它，并通过 maven 设置和下载所有依赖项。这是错误:

我看到很多人滥用 Jersey 1.x 然后显示该错误，但在我的依赖项中我使用的是 2.x 版本，但错误出现了。

最佳答案

尝试添加这个:

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet-core</artifactId>
    <version>2.18</version>
</dependency>

今天最后一个版本是2.26
