Question

在我的applicationcontext.xml中，我收到了以下错误：

在班级中找不到属性'dataSource'的setter 'com.bracketapp.repository.JdbcBracketDetailDao'

我查看了类和界面，并将其与没有此问题的其他人进行了比较。我没有看到这个问题。

这是完整的applicationcontext.xml：

Answer 1

您的JdbcBracketDetailDao是否扩展了JdbcDaoSupport或NamedParameterJdbcDaoSupport？

这两个类都免费提供一个setDataSource。
