java - 我无法使用java导出数据库。谁能帮我？

Question

我正在尝试从 MySQL 数据库(保留)导出单个表(位置)，但我无法使用 java 来做到这一点。请帮助我。

preparedStatement = connection.prepareStatement("mysqldump –uroot –proot keep location> db_test.sql");
        preparedStatement.execute();
        connection.close();

这里是单个表的代码。我们可以将此表保存到文件中。

    Class.forName("com.mysql.jdbc.Driver");
    String url = "jdbc:mysql://localhost:3306/abc";
    String username = "root";
    String password = "root";
    Connection connection = DriverManager.getConnection(url, username, password);

    Statement stmt = connection.createStatement();

    String filename = "d:/outfile.sql";
    String tablename = "abc";
    stmt.executeQuery("SELECT * INTO OUTFILE \"" + filename + "\" FROM " + tablename);
