Question

我是JAVA的新手，我正在尝试提供服务：我想用JAX-RS和Hibernate（JPA）进行测试，这里的任务是将JAX-RS的信息发送到另一个类来保持一个对象Utilisateur和我在目前和很长一段时间之前得到了关于在我的数据库中使用JPA插入新对象的相同错误。当我在我的MAIN课程中进行测试时，我总是得到这个错误：线程＆＃34; main＆＃34;中的例外情况javax.ws.rs.NotAllowedException：HTTP 405方法不允许

这是我的类（我的MAIN，我的服务类，它使对象的持久化，我的Utilisateur类，它是将要持久化的Object类，我的web.xml和我的persistence.xml）。我还要在控制台中发布错误代码：

我的主要课程（测试）：

我是那个论坛的新手，对不起如果我错过了很多东西，真的很抱歉。在那次测试之后，我将创建一个GUI来连接SERVICE和GUI与JSF（xhtml）。你可以看到我不是英国人，对那些错误感到抱歉。

Answer 1

此错误表示您正在尝试向服务器端不允许/存在的方法发出请求

在您的情况下 GET ，您正在尝试发出 GET 请求，但您没有在服务中声明

您的客户代码：

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

和您的服务代码：

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

更改您的服务代码，改为使用@GET。

对于记录：您正在使用REST动词，因为POST应该用于ADD，因此您可能希望更改客户端代码以进行POST，而不是GET。但是你必须改变@QueryParam。这不是在POST中传递params的方式

您可能需要检查此answer，以便在请求中传递POST表单字段。

线程中的@POST异常＆＃34; main＆＃34; javax.ws.rs.NotAllowedException：不允许HTTP 405方法
