Answer 1

首先，根据http://static.springsource.org/spring-social/docs/1.0.x/reference/html/overview.html#overview-dependencies上的文档，Spring Social 仅支持 Spring 3.0.5 或更高。（并且当 Spring Social 1.1.0 发布时，它只会在 Spring 3.1 或更高版本上支持。）

我的第一个建议是至少在Spring 3.0.5 上试用（如果您愿意，最好在 3.0.7 甚至 3.1.2 上试用）。如果那不能解决您的问题，那么我可以更深入地研究一下。
