Question

我有一个Maven jersey服务器，它将json对象发送到我的JavaFX客户端，在我的服务器中，我有具有字符串和int的模型类，在客户端模型类中，我尝试使用Stringproperty和IntegerProperty（用于绑定使用和我有适当的getter和setter（setter = name.set（＆＃34; example＆＃34;）， getter = return name.get））但是当我这样做时我得到

前端和后端都有JSON作为mediatype，当我将客户端模型类变量更改为String和Int时，一切都按预期工作。我想找到一种方法来保持字符串的属性和int的绑定方法，我试图谷歌但没有人似乎有这个问题，有谁知道什么可以解决这个问题，让我使用变量的属性

我抓住了异常 processingException e

e.getCause（）：null

e.getMessage（）：

MessageBodyReader not found for media type=application/json, type=interface java.util.List, genericType=java.util.List<models.Users>.

当我使用postman运行get方法后端工作时，所以告诉我它与客户端的关系。

客户端：玻璃鱼4.1 泽西岛2.5.1（JAX-RS RI） javax.ws.rs-API-2.0.1

服务器：玻璃鱼4.1 球衣2.26-b03

提前致谢！

将以下依赖项添加到客户端，以提供MessageBodyReader实现，该实现知道如何将传入的JSON字符串反序列化为Users实例。

<dependency> 
  <groupId>com.fasterxml.jackson.jaxrs</groupId> 
  <artifactId>jackson-jaxrs-json-provider</artifactId> 
  <version>2.4.4</version> 
</dependency>
