java - JAX-RS:NoSuchMethodFound 异常 Jersey-media-moxy JSON

Question

我已经为此苦苦挣扎了几个小时。我正在使用 jersey 开发 JAX-RS。一切都很顺利，直到我不得不在一处返回 JSON。我知道必须有一个 jersey-media-moxy 库才能将 Java 对象绑定(bind)到 JSON 格式。我从 Jersey-media-moxy 到 Google 的 genson 库，陆续下载了几个 JSON 库。但还没有成功。使用我从 http://www.java2s.com/Code/Jar/j/Downloadjerseymediamoxy23jar.htm 下载的 Jersey-media-moxy ，我在运行 Web 服务时收到以下错误。

如果我使用 MediaType.APPLICATION_XML 更改 @Produces() 注释，一切都会正常工作，但一旦我将其更改为 MediaType.APPLICATION_JSON，我收到错误。

这是一个非 Maven 项目，我通过“项目”->“属性”添加了 jar。我尝试了其他 JSON 库，例如 Jetty、Jackson，但没有一个有效。 Jersey-media-moxy 之外的库会引发 MessageBodyWriter not found 异常。我做错了什么？与依赖有关吗？这是我的项目结构:

在这方面的任何帮助将不胜感激。提前致谢。

Answer 1

我也遇到过同样的问题，花了很长时间才解决。

此问题的基本问题是缺少 jersey-media-moxy-2.27.jar 请求的几个 jarjersey-media-moxy-2.27 jar 内部使用了一些运行时所需的更多 API。

要解决此问题，请参阅随附的快照并确保您的项目中拥有所有 jar(版本很重要) image

建议:如果您使用 Eclipse IDE，认为服务器已“启动”，请尝试在启动服务器(在我的例子中是 Tomcat)时查看控制台日志。不应该有任何错误消息。
