@POST异常在线程“main”javax.ws.rs.NotAllowedException：HTTP 405方法不允许

我是JAVA新手，我正在尝试做一个服务：我想用JAX-RS和Hibernate进行测试（JPA），这里的任务是使用JAX-RS将信息发送给另一个类来持久化一个对象Utilisateur，并且我已经得到了很多时间，然后就在我的数据库中使用JPA插入一个新对象之前的很长一段时间。当我空空我的主类的测试，我总是得到这个错误：异常线程“main” javax.ws.rs.NotAllowedException：HTTP 405不允许的方法@POST异常在线程“main”javax.ws.rs.NotAllowedException：HTTP 405方法不允许

这里是我的课（我的主，我的使持久化对象的服务类，我的Utilisateur类（即将要被持久化的Object类），我的web.xml和我的persistence.xml）。我会还张贴在控制台上的错误代码：

我的主类（测试）：

我在这个论坛很新，很抱歉，如果我错过了很多的东西，真的很抱歉。测试完成后，我将制作一个GUI，将SERVICE和GUI与JSF（xhtml）连接起来。正如你所看到的，我不是英语，对于这些错误感到抱歉。

你的'persistence.xml'和'web.xml'是一样的..这没有任何意义 –

糟糕，我犯了一个错误，我现在就去改变！ – kenb

此错误意味着您正试图使到不允许的方法请求在你的情况在服务器端

/存在，它GET，你正试图使一个GET请求，但你没有它在服务声明

您的客户端代码：

....request(MediaType.APPLICATION_XML).get(Utilisateur.class);

和你的服务代码：

@POST 
@Consumes(MediaType.APPLICATION_XML) 
@Produces(MediaType.TEXT_PLAIN) 
//@Path("/getutil") 
public Utilisateur getUtil....

更改您的服务代码，请改用@GET。

备案：您正在使用REST动词不正确，因为POST应该用于ADD，因此您可能需要更改客户端代码以创建POST，而不是GET。但你必须改变@QueryParam。因为这不是如何在POST中传递参数

您可能需要检查此answer以在请求集中传递POST表单字段。

所以我在行为上犯了一个大错，我现在要改变这些事情。谢谢 – kenb
