今日总结

今天的内容：

学习了Java中对数据库的链接：

需要导包：mysql-connector-java-5.1.39-bin.jar

链接方式：

package DButil;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class GetConnect {
    private Connection conn = null;
    private String driver = "com.mysql.jdbc.Driver";
    private String url = "jdbc:mysql://localhost:3306/people?useUnicode=true"
            + "&serverTimezone=UTC&characterEncoding=utf8&" + "useSSL=false&allowPublicKeyRetrieval=true";
    private String user = "root";
    private String passwd = "passwd";

    public static void main(String[] args) {
        GetConnect gc = new GetConnect();
        gc.GetConn();
    }

    @SuppressWarnings("finally")
    public Connection GetConn() {
        try {
            Class.forName(driver);
            conn = DriverManager.getConnection(url, user, passwd);
            if (!conn.isClosed()) {
                System.out.println("连接成功");
            }
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            return conn;
        }
    }
}

问题：无

明天的打算：继续学习JavaWeb内容
