最近項(xiàng)目需要讀取Excel，將數(shù)據(jù)導(dǎo)入數(shù)據(jù)庫保存，最終可以用報(bào)表讀取數(shù)據(jù)庫并顯示，比較簡單。查了一下兩者的資料，覺的也無所謂，我需要的功能比較簡單，只要能讀取Excel數(shù)據(jù)就行，最后決定使用POI，比較信任apache使用果然很簡單，上網(wǎng)找了個(gè)源碼，Copy過來稍微改改就能用了。下面付的代碼是一個(gè)Demo，功能點(diǎn)有兩個(gè)：一就是POI讀取Excel，二是DB2數(shù)據(jù)庫的連接和SQL執(zhí)行。現(xiàn)在的問題就是這樣做的話代碼太死，針對一張Excel表就要編寫一個(gè)專門的轉(zhuǎn)換類，太麻煩了，要考慮怎么實(shí)現(xiàn)一個(gè)通用轉(zhuǎn)換類。import java.io.FileInputStream;import java.io.IOException;import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;import java.sql.Statement;import org.apache.poi.hssf.usermodel.HSSFCell;import org.apache.poi.hssf.usermodel.HSSFRow;import org.apache.poi.hssf.usermodel.HSSFSheet;import org.apache.poi.hssf.usermodel.HSSFWorkbook;import org.apache.poi.poifs.filesystem.POIFSFileSystem;public class POITest {private static Connection conn = null;private static Statement stmt = null;private static boolean connectDB2() {　String url = "";　String username = "username";　String password = "password";　//加載驅(qū)動程序以連接數(shù)據(jù)庫　try {　 //添加類庫驅(qū)動包db2jcc.jar和db2jcc_license_cu.jar　 Class.forName("com.ibm.db2.jcc.DB2Driver");　 url = "jdbc:db2://192.168.0.1:50000/dbname";　 //添加類庫驅(qū)動包db2java.jar　 //Class.forName("com.ibm.db2.jdbc.app.DB2Driver").newInstance();　 //url = "jdbc:db2:njtcdata";　 conn = DriverManager.getConnection(url, username, password);　 stmt = conn.createStatement();　}　//捕捉加載驅(qū)動程序異常　catch (ClassNotFoundException cnfex) {　 System.err.println("裝載JDBC驅(qū)動程序失敗。");　 cnfex.printStackTrace();　 return false;　}　//捕捉連接數(shù)據(jù)庫異常　catch (SQLException sqlex) {　 System.err.println("無法連接數(shù)據(jù)庫");　 sqlex.printStackTrace();　 //System.exit(1); // terminate program　 return false;　}　return true;}private static boolean readExcelToDB2() {　POIFSFileSystem fs = null;　HSSFWorkbook wb = null;　try {　 fs = new POIFSFileSystem(new FileInputStream("c:test.xls"));　 wb = new HSSFWorkbook(fs);　} catch (IOException e) {　 e.printStackTrace();　 return false;　}　HSSFSheet sheet = wb.getSheetAt(0);　HSSFRow row = null;　HSSFCell cell = null;　String name = "";　int id = 0;　int rowNum, cellNum;　int i;　rowNum = sheet.getLastRowNum();　for (i = 0; i <= rowNum; i++) {　 row = sheet.getRow(i);　 //cellNum = row.getLastCellNum();　 cell = row.getCell((short) 0);　 name = cell.getStringCellValue();　 cell = row.getCell((short) 1);　 id = (int) cell.getNumericCellValue();　 String sql = "insert into TEST(ID, NAME) values(" + id + ",'" + name + "')";　 try {stmt.executeUpdate(sql);　 } catch (SQLException e1) {e1.printStackTrace();return false;　 }　}　return true;}public static void main(String[] args) {　if (connectDB2()==true){　 if (readExcelToDB2()==true)System.out.println("數(shù)據(jù)導(dǎo)入成功");　 elseSystem.out.println("數(shù)據(jù)導(dǎo)入失敗");　}　else{　 System.out.println("數(shù)據(jù)庫連接失敗");　}}}
