上一文章写得有点复杂，需要创建datasource，然后还有一大堆的封装方法，这里参考官网上（https://bitbucket.org/xerial/sqlite-jdbc#markdown-header-usage）的示例，如下：

具体流程
（1）Connection conn = DriverManager.getConnection("jdbc:sqlite:***/smaple");

（2）Statement statement = conn.createStatement();

（3）statement.executeUpdate("select/insert/drop/delete等sql语句");

（4）conn.close()

注意：关于在windows/Linux/以及在内存上创建sqlite数据库有一下集中方法：

（1）Windows上创建connection

Connection connection = DriverManager.getConnection("jdbc:sqlite:C:/work/mydatabase.db");

（2）Linux上创建connection

Connection connection = DriverManager.getConnection("jdbc:sqlite:/home/leo/work/mydatabase.db");

（3）没有db文件，只在内存上临时创建

Connection connection = DriverManager.getConnection("jdbc:sqlite::memory:");

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.sqlException;
import java.sql.Statement;

public class Sample
{
  public static void main(String[] args) throws ClassNotFoundException
  {
    // load the sqlite-JDBC driver using the current class loader
    Class.forName("org.sqlite.JDBC");

    Connection connection = null;
    try
    {
      // create a database connection
      connection = DriverManager.getConnection("jdbc:sqlite:sample.db");
      Statement statement = connection.createStatement();
      statement.setQueryTimeout(30);  // set timeout to 30 sec.

      statement.executeUpdate("drop table if exists person");
      statement.executeUpdate("create table person (id integer,name string)");
      statement.executeUpdate("insert into person values(1,'leo')");
      statement.executeUpdate("insert into person values(2,'yui')");
      ResultSet rs = statement.executeQuery("select * from person");
      while(rs.next())
      {
        // read the result set
        System.out.println("name = " + rs.getString("name"));
        System.out.println("id = " + rs.getInt("id"));
      }
    }
    catch(sqlException e)
    {
      // if the error message is "out of memory",
      // it probably means no database file is found
      System.err.println(e.getMessage());
    }
    finally
    {
      try
      {
        if(connection != null)
          connection.close();
      }
      catch(sqlException e)
      {
        // connection close Failed.
        System.err.println(e);
      }
    }
  }
}
