... 32 more麻烦问一下  这是怎么造成的，小弟刚开始看spring

Answer 1

从现有错误能分析出，有可能是你PersonServiceBean中，datasource的注入有问题。

Answer 2

这是我的配置文件你看看对吗？谢谢了

Answer 3

PersonServiceBean类里面 没有为dataSource对象 提供set方法

Answer 4

同意，看看你PersonServiceBean这个类的dataSource这个成员变量，有get set方法吗，注意的是，这个成员变量必须是dataSource，大小写必须一致，getDataSource，setDataSource，Spring是把成员变量首字母大写再Get Set的 

Answer 5

Answer 6

对了 忘了给set方法了  不好意思了   谢谢大家了
