是否可以在同一个项目中使用jersey和java websockets（ServerEndpoint）

Question

当我使用jersey开发一个rest api应用程序时，我遇到了一个问题，我需要为特定的业务逻辑部分实现一个websocketendpoint。

我提出这个问题是因为我认为jersey与javaee-api工件之间存在一些依赖关系冲突。

Answer 1

当然，您可以在同一个项目中使用WebSocket和RS服务。

要向maven项目添加WebSocket支持，请向POM添加以下依赖项。

 <dependency>
     <groupId>javax.websocket</groupId>
     <artifactId>javax.websocket-api</artifactId>
     <version>1.1</version>
     <scope>provided</scope>
 </dependency>
