Unable to resolve db.properties, spring error: Caused by: java.sql.SQLException: unkow jdbc driver: $ {url} ...

db.properties configured in jdbc url like connection properties:

driver=org.sqlite.JDBC
url=jdbc:sqlite:D:/xxx/data/sqliteDB/demo.db
username=
password=

applicationContext.xml spring of configuration data source reference these properties, but unfortunately, being given the run:

Caused by: java.sql.SQLException: unkow jdbc driver : ${url}

solution:

The MapperScannerConfigurer section of the bean property sqlSessionFactory

<property name="sqlSessionFactory" ref="sqlSessionFactory" />

改成：<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
