Question

我有一个ResponseModel类，我想发送它的对象以响应休息。但是我收到了这个错误：

Java类的消息正文编写器 com.tcs.srl.message.model.ResponseModel和Java类型类 com.tcs.srl.message.model.ResponseModel和MIME媒体类型找不到application / json。

我无法在我的项目中使用Maven。因此无法在pom.xml中添加jersey依赖项。

检查是否在Jersery功能的类路径中包含了所有必需的依赖项。我想你错过了杰克逊特色：

检查您的类路径中是否添加了jersey-media-json-jackson-<required-vesrion>.jar。
