以下是我写的连接数据库的java类：
package com.neuedu.db;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBConnection {
private static final String URL="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=HRMS";
private static final String USERNAME="sql_dota";
private static final String PASSWORD="123456";
static{
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static Connection getConnection() {
Connection conn=null;
try {
conn = DriverManager.getConnection(URL, USERNAME, PASSWORD);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return conn;
}
} MyEclipse SQL?Server
