我正在尝试创建一个普通示例，该示例将使用 json 消息并将其注入 pojo 对象。

我正在使用支持 JavaEE7 的 Netbeans 开发版本和最新的 Glassfish 4 升级版本。

当我使用 json 消息调用 Post 方法时，我在日志中获得了 stackstrace。在这一点上，我不知道我是否做错了什么。我期待它在 jax-rs 2 中正常工作。

帮助将不胜感激。

这里是堆栈跟踪和源代码。

如果其他人有同样的问题，我会打开一个 Jira 问题来跟踪它。

对于 JAX-RS 2.0，使用标准的 JAX-RS 客户端 API，而不是 Jersey 客户端 API。所以，像：

public static void main(String[] args){
    javax.ws.rs.client.Client client = javax.ws.rs.client.ClientBuilder.newClient();

    User user = new User();
    user.name="name1";
    user.lastname="lastname2";

    javax.ws.rs.client.WebTarget myResource = client.target("http://localhost:8080/WebApplication1/resources");
    myResource.request(MediaType.APPLICATION_JSON)
        .post(user);

    client.close();
}

我不确定为什么 Jersey Client API 在这种情况下不起作用。
