↳ | org.springframework.jdbc.core.support.JdbcBeanDefinitionReader |
Bean definition reader that reads values from a database table, based on a given SQL statement.
Expects columns for bean name, property name and value as String. Formats for each are identical to the properties format recognized by PropertiesBeanDefinitionReader.
NOTE: This is mainly intended as an example for a custom JDBC-based bean definition reader. It does not aim to offer comprehensive functionality.
