我也尝试过使用XMl格式，在pojo/resource/client中使用相应的注释，但出现了相同的HTTP405错误

据我所知，传递对象时应使用

应用程序/json

媒体类型。因此，我会在所有代码中使用它，并在

客户端中使用它。制作。
尝试以下步骤来解决上述问题
将consumes从纯文本更改为JSON（@consumes（MediaType.ApplicationJson））
在rest客户端中，使用下面的代码创建JSON POST请求使用以下代码
ClientResponse response=webResource.type（“应用程序/json”）
.post（ClientResponse.class，输入）；
尝试从外部rest客户机（如postman）调用该服务，看看它是如何实现的
去
最重要的是，请在名为“Track”的bean上实现可序列化的接口

@vinS这里的所有内容都是分析问题所需要的。请在提问时具体说明。发布整个代码对任何人都没有帮助。抱歉。当从客户端（JerseyclientPost）向Rest资源（JSONservice）发送post请求时，我收到HTTP 405错误-不允许使用方法。我只是尝试用客户端的数据创建一个跟踪（Pojo类）。对于客户端发送的请求类型，我尝试了JSON和纯文本MediaType。但我得到了HTTP 405错误。如果你需要关于这个问题的任何信息，请告诉我
