java中使用sqlite

一、下载SQLite数据库的JDBC：http://www.zentus.com/sqlitejdbc/

二、将下载到的包解压后得到jar包放到%JAVA_HOME%\lib下，并且将其添加到ClassPath系统环境变量中。一定要保证在类路径ClassPath中有该jar包，并且保证在JAVA库路径JAVA Library Path中有本地库Native Library（\workspace\"Web应用"\WebRoot\WEB-INF\lib\下最好也要加入该jar包）。"SQLite.JDBCDriver"作为JDBC的驱动程序类名。连接JDBC的URL格式为jdbc:sqlite:/path。这里的path为指定到SQLite数据库文件的路径，例如：

jdbc:sqlite://dirA/dirB/dbfile

jdbc:sqlite://DRIVE:/dirA/dirB/dbfile

jdbc:sqlite://COMPUTERNAME/shareA/dirB/dbfile

三、下面是使用SQLite的两段代码以供参考：

代码段1：

import java.sql.*; import org.sqlite.JDBC;  public class SQLiteTest {     public static void main(String[] args) {         try {             // The SQLite (3.3.8) Database File             // This database has one table (pmp_countries) with 3 columns (country_id, country_code, country_name)             // It has like 237 records of all the countries I could think of.             String fileName = "c:/pmp.db";             // Driver to Use             // http://www.zentus.com/sqlitejdbc/index.html             Class.forName("org.sqlite.JDBC");             // Create Connection Object to SQLite Database             // If you want to only create a database in memory, exclude the +fileName             Connection conn = DriverManager.getConnection("jdbc:sqlite:"+fileName);             // Create a Statement object for the database connection, dunno what this stuff does though.             Statement stmt = conn.createStatement();             // Create a result set object for the statement             ResultSet rs = stmt.executeQuery("SELECT * FROM pmp_countries ORDER BY country_name ASC");             // Iterate the result set, printing each column             // if the column was an int, we could do rs.getInt(column name here) as well, etc.             while (rs.next()) {                 String id   = rs.getString("country_id");   // Column 1                 String code = rs.getString("country_code"); // Column 2                 String name = rs.getString("country_name"); // Column 3                 System.out.println("ID: "+id+" Code: "+code+" Name: "+name);              }             // Close the connection             conn.close();         }         catch (Exception e) {             // Print some generic debug info             System.out.println(e.getMessage());             System.out.println(e.toString());         }     } }
