我尝试使用maven的泽西服务器发送事件。但是当我使用eventSource发出请求时，我有一个错误
javax.ws.rs.WebApplicationException: com.sun.jersey.api.MessageException: A message body writer for Java class org.glassfish.jersey.media.sse.EventOutput, and Java type class org.glassfish.jersey.media.sse.EventOutput, and MIME media type text/event-stream was not found.

我觉得我的项目缺少一些东西。我该如何解决这个问题？
