解决方案 »

  1.   

    jackson的包太旧了，换个新版本<dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.5.4</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.5.4</version>
    </dependency>
      

  2.   

    我没有用到jackson的包啊
      

  3.   

    可能默认用json格式来传送数据吧，DefaultSockJsService中用了jackson的东东。

    at org.springframework.web.socket.sockjs.transport.handler.DefaultSockJsService.<init>(DefaultSockJsService.java:74)没有的话就加一个jackson的依赖
