javax.sql.DataSource 这个 maven 仓库没有，怎么办

[chaegumi]

不是 java 程序员来配置 cas 好吃力，眼看就要成功了，配置到使用数据库认证时，报错，这个包 maven 仓库中又没有，搜索不到合适的文章，文章里边的方法都试了，没用

[letitbesqzr]

这不是 jdk 里带的？

@chaegumi 说的是 cas jdbc 包下的 queryAndEncodeDatabaseAuthenticationHandler 需要注入一个 javax.sql.DataSource 类型的对象。。 但是没找到任何 type 为 DataSource 的 bean 。 自己定义一个就可以

[chaegumi]

@letitbesqzr 难怪我都搜索不到答案，对懂 java 的人来说是小问题，因为我本身就理解错了 log ，听了你的解释后就懂了，就是不知道在哪里配置，我还得继续查资料， thanks 。

[letitbesqzr]

@chaegumi 目测是 jasig 的 cas ？

[chaegumi]

@letitbesqzr 是的

javax.sql.DataSource 是 jdk 自带的，这个是个接口，几乎所有连接池都会实现这个接口。
