直接上代码web

public class SqlUtils {

private static final String DRIVERCLASS;

private static final String URL;

private static final String USERNAME;

private static final String PASSWORD;

static {

DRIVERCLASS = ResourceBundle.getBundle("SqlServerJdbc").getString("driverClass");

URL = ResourceBundle.getBundle("SqlServerJdbc").getString("url");

USERNAME = ResourceBundle.getBundle("SqlServerJdbc").getString("username");

PASSWORD = ResourceBundle.getBundle("SqlServerJdbc").getString("password");

}

static {

try {

Class.forName(DRIVERCLASS);

} catch (ClassNotFoundException e) {

e.printStackTrace();

}

}

public static Connection getConnection() throws SQLException {

// 2.获取链接

Connection con = DriverManager.getConnection(URL, USERNAME, PASSWORD);

// Connection con = DriverManager.getConnection(URL, USERNAME, PASSWORD);

return con;

}

// 关闭操做

public static void closeConnection(Connection con) throws SQLException {

if (con != null) {

con.close();

}

}

public static void closeStatement(Statement st) throws SQLException {

if (st != null) {

st.close();

}

}

public static void closeResultSet(ResultSet rs) throws SQLException {

if (rs != null) {

rs.close();

}

}

}

注意此工具内配合配置文件使用(SqlServerJdbc.properties)，配置文件内容以下：sql

driverClass=com.microsoft.sqlserver.jdbc.SQLServerDriver

url=jdbc:sqlserver://IP;databaseName=DBName

username=username

password=userpwd

测试代码以下数据库

public class SqlserverTest {

public static void main(String[] args) throws Exception {

// 建立链接

Connection con = null;

try {

con = SqlUtils.getConnection();

System.out.println("SQL数据库连接ok！");

} catch (SQLException e) {

e.printStackTrace();

System.out.println("SQL数据库连接失败！");

}

try {

SqlUtils.closeConnection(con);

} catch (SQLException e) {

e.printStackTrace();

}

}

}
