将Jersey客户端1.x升级到2.x时，UriBuilder上的AbstractMethodError

Question

我们正在将我们的Web应用程序（在Tomcat7上运行）从Jersey 1.7升级到Jersey 2.4.1。 我设法让服务器端正在运行，但是使用jersey-client的JUnit测试抛出了AbstractMethodError：java.lang.AbstractMethodError：

该项目由maven维护，这里是pom的依赖项：

显然我错过了UriBuilder类的具体实现，但我不知道我需要为此添加什么依赖项。 此外 - 它适用于服务器端，但是！？

Answer 1

我发现enunciate库在某种程度上取决于球衣1.1.7。 这导致我的代码的一部分编译正常，但仍依赖于1.1.7 API。

我通过查找找到了它：

find . -name *.pom -exec grep -Hn jersey {} \;

...在球衣上的〜/ .m2文件夹中。 只有当您的应用是您机器上唯一使用maven的应用时，才能执行此操作。

Answer 2

当您看到此错误时，表示正在从其他库（如cxf-2.1.3.jar）加载UriBuilder。 只需将其重命名为z-cxf-2.1.3.jar即可。 它应该工作正常。在maven中找到哪个依赖项带来jar并使用这样的东西

<dependency>
    <groupId>${project.groupId}</groupId>
