                javax.persistence.jdbc.driver在JPA的值是JDBC驱动，Redkale有所不同，值应该是javax.sql.DataSource的子类。 
                为了兼容用户习惯，Redkale内置常见JDBC驱动到javax.sql.DataSource的映射关系：
                                     org.mariadb.jdbc.Driver  ——————  org.mariadb.jdbc.MySQLDataSource
                                       org.postgresql.Driver  ——————  org.postgresql.ds.PGConnectionPoolDataSource
                                       com.mysql.jdbc.Driver  ——————  com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
                             oracle.jdbc.driver.OracleDriver  ——————  oracle.jdbc.pool.OracleConnectionPoolDataSource
                com.microsoft.sqlserver.jdbc.SQLServerDriver  ——————  com.microsoft.sqlserver.jdbc.SQLServerConnectionPoolDataSource
                因此 com.mysql.jdbc.Driver 会被自动转换成 com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
                并且如果JDBC驱动是以上几个版本，javax.persistence.jdbc.driver属性都可以省略，Redkale会根据javax.persistence.jdbc.url的值来识别驱动
