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

完整的堆栈跟踪是：

看来Spring Social使用的是Jackson的最新版本，即1.9版本，方法JsonNode.asLong()是1.9版本的新方法

比较1.8和1.9的 JavaDoc

spring-social 1.0.1 和 jackson 1.9.2 没有问题。最新的 spring-social 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

询问 ：

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

您可以从以下网址获取最新版本：http ://www.springsource.org/spring-social
