Json 如何在jersey中的rest上发送对象作为响应

我有一个ResponseModel类，我想把它的对象发送给rest。但我得到了这个错误：

Java类的消息体编写器 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

我不能在我的项目中使用Maven，所以不能在pom.xml中添加jersey依赖项

检查是否已在Jersery功能的类路径中包含所有必需的依赖项。我认为您没有包括杰克逊的功能：

检查是否在类路径中添加了jersey media json jackson-.jar。

我的项目中没有maven。那么我可以添加pom.xml吗？？？我已经用ANT构建了我的项目。@SonalRuhatiya对不起，我误解了你的问题。修改了我的答案。在我的Web INF->lib文件夹1asm-3.3.1.jar 2jersey-bundle-1.14.jar 3jersey-client-1.17.jar 4json-simple-1.1.1.jar 5logback-access-1.0.9.jar 6logback-classic-1.0.13.jar 7logback-core-1.0.13.jar 8servlet-api.jar 9slf4j-api-1.7.2.jar 10slf4j-ext-1.6.1.1.jar中，我添加了项目构建路径中的1 jackson-core-asl-1.9.2.jar 2 jackson-mapper-asl-1.9.2.jar。但它仍然不起作用。这是同样的例外…这是我在回答中写的。为所需版本添加jersey-media-json-jackson.jar。将jersey-media-json-jackson.jar添加到类路径中，但仍然不起作用
