Question

我正在开发一个使用Spring Social API访问Twitter帐户的应用程序。与Twitter的连接成功建立。我能够检索关注者，个人资料名称和朋友的数量。当我尝试检索用户的推文时，我得到了java.lang.NoSuchMethodError异常。

完整堆栈跟踪是：

非常感谢任何帮助。

Answer 1

Spring Social似乎使用了最新版本的Jackson，版本为1.9，方法JsonNode.asLong()是版本1.9的新版本

比较1.8和1.9

的JavaDoc

Answer 2

spring-social 1.0.1和jackson 1.9.2没有问题。最新的spring-social软件包支持jackson 1.9。

spring-social-core-1.0.1.RELEASE.jar
spring-social-twitter-1.0.1.RELEASE.jar
jackson-all-1.9.2.jar

查询：

List<Tweet> tweets = twitterApi.timelineOperations().getHomeTimeline();

您可以从http://www.springsource.org/spring-social

获取最新版本
