从 Eclipse 访问 Wamp 服务器数据库

Question

我想使用 Java 访问我计算机中的 Wamp 服务器数据库。我的代码如下：

public static void main(String[] args)
    {
        try
        {
            // create our mysql database connection
            String myDriver = "com.mysql.jdbc.Driver";
            String myUrl = "jdbc:mysql://localhost:3306/deneme";
            Class.forName(myDriver);
            Connection conn = DriverManager.getConnection(myUrl, "root", "");

            // our SQL SELECT query. 
            // if you only need a few columns, specify them by name instead of using "*"
            String query = "SELECT * FROM users";

            // create the java statement
            Statement st = conn.createStatement();

            // execute the query, and get a java resultset
            ResultSet rs = st.executeQuery(query);

            // iterate through the java resultset
            while (rs.next())
            {
                int id = rs.getInt("id");
                String firstName = rs.getString("first_name");
                String lastName = rs.getString("last_name");
                Date dateCreated = rs.getDate("date_created");
                boolean isAdmin = rs.getBoolean("is_admin");
                int numPoints = rs.getInt("num_points");

                // print the results
                System.out.format("%s, %s, %s, %s, %s, %s\n", id, firstName, lastName, dateCreated, isAdmin, numPoints);
            }
            st.close();
        }
        catch (Exception e)
        {
            System.err.println("Got an exception! ");
            System.err.println(e.getMessage());
        }

在此之后，它给我这个错误：

Got an exception! 
com.mysql.jdbc.Driver

如何将我自己计算机中的数据库连接到 java？

谢谢

尝试在 /lib 文件夹中添加 mysql-connector-java-xxxx-bin.jar。
您可以从 here.
下载然后右击 project properties --> Java Build Path --> External jar
