我在我自己的机器上安装了MySql。我创建了数据库,创建表,...使用MySql CommandLine Client。在学校的一个项目工作时,我使用此语法连接到学校数据库:如何使用JDBC连接到本地主机?
public static Statement connect() {
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("1", "2", "3");
stmt = conn.createStatement();
}
catch(Exception e) {
System.out.println("Connection Error: " + e);
}
return stmt;
}
在我的本地机器,我就不必输入用户名,我所做的只是用我的密码登录root用户:
Enter password: ****

我想知道如何连接到本地机器的数据库?我应该把作为参数的方法.getConnection内
conn = DriverManager.getConnection(
"1", // ?
"2", // ?
"3" ); // ?
最好的问候,
陈
伙计,从您的代码段删除用户名和密码,尽快!当你处于这个状态时,也要删除主机名。你也不需要在错误的'show tables'中输入代码片段 – Todd 2010-12-14 05:33:03
