详细说明：在Java下连接SQLite数据库一、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： 1 impor t java.sql.*; 2 import org.sqlite.JDBC; 3 4 public class SQLiteTest { 5 public static void main(String[] args) { 6 try { 7 // The SQLite (3.3.8) Database File 8 // This database has one table (pmp_countries) with 3 columns (country_id, country_code, country_name) 9 // It has like 237 records of all the countries I could think of. 10 String fileName = "c:/pmp.db"; 11 // Driver to Use 12 // http://www.zentus.com/sqlitejdbc/index.html 13 Class.forName("org.sqlite.JDBC"); 14 // Create Connection Object to SQLite Database 15 // If you want to only create a database in memory, exclude the +fileName 16 Connection conn = DriverManager.getConnection("jdbc:sqlite:"+fileName); 17 // Create a Statement object for the database connection, dunno what this stuff does though. 18 Statement stmt = conn.createStatement(); 19 // Create a result set object for the statement 20 ResultSet rs = stmt.executeQuery("SELECT * FROM pmp_countries ORDER BY country_name ASC"); 21 // Iterate the result set, printing each column 22 // if the column was an int, we could do rs.getInt(column name here) as well, etc. 23 while (rs.next()) { 24 String id = rs.getString("country_id"); // Column 1 25 String code = rs.getString("country_code"); // Column 2 26 String name = rs.getString("country_name"); // Column 3 27 System.out.println("ID: "+id+" Code: "+code+" Name: "+name); 28 29 } 30 // Close the connection 31 conn.close(); 32 } 33 catch (Exception e) { 34 // Print some generic debug info 35 System.out.println(e.getMessage()); 36 System.out.println(e.toString()); 37 } 38 } 39 } 代码段2： 1 import java.sql.*; 2 import org.sqlite.JDBC; 3 /** 4 * 这是个非常简单的SQLite的Java程序, 5 * 程序中创建数据库、创建表、然后插入数据， 6 * 最后读出数据显示出来 7 * @author zieckey (http://zieckey.cublog.cn) 8 */ 9 public class TestSQLite{ 10 public static void main(String[] args){ 11 try{ 12 //连接SQLite的JDBC 13 Class.forName("org.sqlite.JDBC"); 14 //建立一个数据库名zieckey.db的连接，如果不存在就在当前目录下创建之 15 Connection conn = DriverManager.getConnection("jdbc:sqlite:zieckey.db"); 16 Statement stat = conn.createStatement(); 17 18 stat.executeUpdate( "create table tbl1(name varchar(20), salary int);" );//创建一个表，两列 19 stat.executeUpdate( "insert into tbl1 values('ZhangSan',8000);" ); //插入数据 20 stat.executeUpdate( "insert into tbl1 values('LiSi',7800);" ); 21 stat.executeUpdate( "insert into tbl1 values('WangWu',5800);" ); 22 stat.executeUpdate( "insert into tbl1 values('ZhaoLiu',9100);" ); 23 24 ResultSet rs = stat.executeQuery("select * from tbl1;"); //查询数据 25 26 while (rs.next()) { //将查询到的数据打印出来 27 System.out.print("name = " + rs.getString("name") + " "); //列属性一 28 System.out.println("salary = " + rs.getString("salary")); //列属性二 29 } 30 rs.close(); 31 conn.close(); //结束数据库的连接 32 } 33 catch( Exception e ) 34 { 35 e.printStackTrace ( ); 36 } 37 } 38 } ...展开收缩
