java - 首次需要使用Java在Eclipse上设置SQLite的帮助

我一直试图找出如何使Eclipse juno上的SQLite工作。我一直遵循http://wiki.eclipse.org/Connecting_to_SQLite这个网站上的指示。问题不是每一步都完全按照解释来做，所以我猜测天气是否正确。我觉得在步骤13之前，我可能已经全部正确，没有SQL Model-JDBC Connection条目。因此，我尝试了使用通用JDBC和一个说SQLite的步骤13-16。由于第5步，SQLite没有驱动程序也就不足为奇了。到目前为止，我尝试过的任何方法最终都会导致无法ping并列出以下详细信息。有人必须在此过程中有更好的方法。

java.sql.SQLException: java.lang.UnsatisfiedLinkError: SQLite.Database.open(Ljava/lang/String;I)V

最佳答案

确保从https://bitbucket.org/xerial/sqlite-jdbc/downloads获取驱动程序，然后将驱动程序导入项目。



现在，您可以通过创建Java类Sample.java来测试配置

   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)");

         int ids [] = {1,2,3,4,5};
         String names [] = {"Peter","Pallar","William","Paul","James Bond"};

         for(int i=0;i<ids.length;i++){
              statement.executeUpdate("INSERT INTO person values(' "+ids[i]+"', '"+names[i]+"')");
         }

         //statement.executeUpdate("UPDATE person SET name='Peter' WHERE id='1'");
         //statement.executeUpdate("DELETE FROM person WHERE id='1'");

           ResultSet resultSet = statement.executeQuery("SELECT * from person");
           while(resultSet.next())
           {
              // iterate & read the result set
              System.out.println("name = " + resultSet.getString("name"));
              System.out.println("id = " + resultSet.getInt("id"));
           }
          }

     catch(SQLException e){  System.err.println(e.getMessage()); }
      finally {
            try {
                  if(connection != null)
                     connection.close();
                  }
            catch(SQLException e) {  // Use SQLException class instead.
               System.err.println(e);
             }
      }
  }
 }

该代码将创建一个名为sample.db的数据库，将数据插入其中，然后打印行。
