java - Netbeans的RESTful Java客户端:javax.ws.rs.NotAcceptableException:HTTP 406 Not Acceptable

我正在使用Netbeans的RESTful Web服务开发Web服务。服务类包含以下方法：

@Path("jpost")
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.TEXT_PLAIN)
public String jpost(Car c){
    return "Car:"+c.getTag()+"\t"+c.getName()+"\t"+c.getColor();
}

为了测试此方法，我使用Netbeans的RESTful Java Client生成测试方法。结果是：

public String jpost(Object requestEntity) throws ClientErrorException {
        return webTarget.path("jpost").request(javax.ws.rs.core.MediaType.APPLICATION_JSON).post(javax.ws.rs.client.Entity.entity(requestEntity, javax.ws.rs.core.MediaType.APPLICATION_JSON), String.class);
    }

当我致电jpost时，出现以下错误：

Exception in thread "main" javax.ws.rs.NotAcceptableException: HTTP 406 Not Acceptable

    at myserver.test5.jpost(test5.java:36)
    at myserver.MyServerTest.main(MyServerTest.java:32)

问题是什么？

最佳答案

您的服务仅产生text/plain响应。

HTTP代码406表示服务器无法提供客户端可以接受的内容类型。因此，客户端要么在Accepts标头中指定了错误的内容类型，要么根本没有发送Accepts。

要指定可接受的类型，请使用request(...)参数。

public String jpost(Object requestEntity) throws ClientErrorException
{
    return webTarget.path("jpost")
            .request(javax.ws.rs.core.MediaType.TEXT_PLAIN)
            .post(javax.ws.rs.client.Entity.entity(requestEntity, javax.ws.rs.core.MediaType.APPLICATION_JSON), String.class);
}
