实现数据库连接之前,我们要先理解一下URL(统一资源定位器): 是跟数据库进行连接的时候,用来连接到指定远程数据库标识符。 可以在该URL中指定连接用户名和密码,同时,对于不同的数据库有不同的标识。 URL 统一资源定位符 URL包括:协议、IP、port端口、资源名 URL示例:jdbc:mysql://127.0.0.1:3306/mysql jdbc:mys...
Java(使用JDBC): Connectionconn=DriverManager.getConnection("jdbc:mysql://hostname:port/database?user=username&password=password"); System.out.println(conn.getMetaData().getURL()); 获取MySQL数据库的URL地址并非难事,重要的是选择合适的方法,结合自己的具体需求,以提高工作效率。以上方法供你参考,希望能帮...
