具有两个不同版本 Jersey 服务器的 Java 客户端

Question

我有一个连接到使用 jersey 版本 1.19 实现的 java 服务器(服务器 A)的 java 客户端，因此我将相同版本的 jersey 客户端添加到我的 pom 中，一切正常。 不需要我的客户端连接使用 jersey 版本 2.17 实现的其他 java 服务器(服务器 B)，然后问题就开始了...... 当我尝试向服务器 B 发送请求时，我收到 org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException ，并且对于服务器 A，所有请求都工作正常。经过一番研究，我明白我需要更改 pom 文件中的 Jersey 客户端版本。 然后对服务器 B 的请求工作正常，但对服务器 A 的请求遇到相同的异常，我尝试将两个 Jersey 客户端版本放入我的 pom 中，只有服务器 B 工作正常。 有什么方法可以让我使用两种版本的 Jersey 服务器吗？

我的pom文件中的依赖项

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>

我得到的异常堆栈跟踪:

Answer 1

我通过使用另一个名为 Unirest 的休息客户端成功解决了这个问题，该客户端与两台服务器都可以正常工作。谢谢
