将使用javax.ws.rs。*和javax.xml.bind。*编写的RESTful Web服务客户端转换为工作

Question

我编写了这个宁静的Web服务客户端，以使用JAX-RS Web服务。我想在android上使用它，但是android不支持javax.ws或javax.xml.bind库。有没有一种简单的方法就可以将代码转换为可在android上工作而无需进行彻底检修？如果没有，我可以使用什么简单的android restful webservice API？

private Client client;

public DatabaseService() {            
    client = ClientBuilder.newClient();
}
