Javax Jersey 客户端处理异常

Question

我有一个 Maven jersey 服务器，它向我的 JavaFX 客户端发送 json 个对象，在我的服务器中我有模型 classes，它有字符串和 int，在客户端模型中 class 我尝试使用 String属性和 IntegerProperty（用于绑定，我有适当的 getter 和 setters(setter = name.set("example"), getter = return name.get)) 但是当我这样做时我得到

前端和后端都有 JSON 作为媒体类型，当我将客户端模型 class 变量更改为 String 和 Int 时，一切正常，因为 expected.I 希望找到一种方法来保持属性的字符串和 int 的绑定方法，我尝试 google 但似乎没有其他人遇到过这个问题，有谁知道可以解决这个问题并让我使用属性的变量

我发现了异常处理异常 e

e.getCause(): 空

e.getMessage():

当我运行获取后端工作的邮递员方法时，这告诉我它与客户端有关。

客户：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您的客户端以提供 MessageBodyReader 实现，该实现知道如何将传入的 JSON 字符串反序列化为 Users 的实例。

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