我正在将一个活跃的Spring Web应用程序迁移到spring boot(1.4.2).

bean在使用@ImportResource加载时在XML中定义.

我开始的4个bean是同一个对象BasicDataSource的一个实例.

要告诉spring哪个加载我已经为每个设置了一个ID并使用@Qualifier将正确的bean绑定到变量.

但似乎Spring忽略了我的@Qualifier并抛出"没有类型'javax.sql.DataSource'的限定bean可用:预期单个匹配bean但找到4:DataSource1,DataSource2,DataSource3,DataSource4"

PS - 请注意,具有@Qualifier的类是抽象类,而未能实例化的类是扩展类,但@Qualifier具有@Inherited.

什么是使用python访问SF数据的最简单方法？

我需要它只是为了读取目的.

我尝试过使用BeatBox,但似乎与3.3兼容.
