如何在java中添加驱动程序,java – 驱动程序类如何位于JDBC4中

When the method getConnection is called,the DriverManager will

attempt to locate a suitable driver from among the JDBC drivers that

were loaded at initialization and those loaded explicitly using the

same class loader as the current application.

The DriverManager methods getConnection and getDrivers have been

enhanced to support the Java SE Service Provider mechanism (SPM).

According to SPM,a service is defined as a well-known set of

interfaces and abstract classes,and a service provider is a specific

implementation of a service. It also specifies that the service

provider configuration files are stored in the Meta-INF/services

directory. JDBC 4.0 drivers must include the file

Meta-INF/services/java.sql.Driver. This file contains the name of the

JDBC driver’s implementation of java.sql.Driver. For example,to load

the JDBC driver to connect to a Apache Derby database,the

Meta-INF/services/java.sql.Driver file would contain the following

entry:
