Jakarta POI төсөл нь Microsoft-ийн Word, Excel гэх мэтийн баримтуудыг JAVA орчинд бүтээх зорилготой юм. Доор байгаа пакеж болон компонентууд нь POI төсөлд агуулагдана.
POIFS (Энэ нь болохоор JAVA-г ашиглаад OLE2 нийлмэл баримтын бүтцийг унших болон бичихэд зориулсан API багц юм)
HSSF (Мөн JAVA-г ашиглаад Microsoft Excel 97(-XP)-ийн sheet-ийг уншиж, бичихэд зориулсан API багц юм)
HWPF (Мөн JAVA-г ашиглаад Microsoft Word 97(-XP)-ийн баримтыг уншиж, бичихэд зориулсан API багц юм)
HPSF (JAVA дээр Property багцийг уншиж, бичихэд зориулсан API багц юм)
Дээрхээс миний хэрэглэж үзсэн нь HSSF юм. Жишээнүүдийг ашиглахын өмнө Jar файлыг өөрийн санд хуулах шаардлагатай. JAR Download
Мөн Eclipse ашиглан жишээг ажиллуулбал тохиромжтой. Жишээнд Import хийдэг хэсгийг хассан тул анхаараарай.
HSSF нь JAVA дээрээс Excel 97(-XP) файлын форматтай ажилладаг POI төслийн нэг хэсэг юм.
HSSF-ийг хэрэглэж Excel-ийн Sheet-нд өгөгдөл бичих, Sheet-ээс өгөгдөл унших, Sheet үүсгэх, засварлах зэрэг үйлдлийг хийж болно. Доорх жишээнүүдийг харна уу.
Шинэ Workbook үүсгэх
HSSFWorkbook wb = new HSSFWorkbook();
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
Шинэ Sheet үүсгэх
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet1 = wb.createSheet("new sheet");
HSSFSheet sheet2 = wb.createSheet("second sheet");
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
Нүднүүд үүсгэх
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("new sheet");
// Create a row and put some cells in it. Rows are 0 based.
HSSFRow row = sheet.createRow((short)0);
// Create a cell and put a value in it.

// Or do it on one line.

row.createCell((short)3).setCellValue(true);
// Write the output to a file

// Create a row and put some cells in it. Rows are 0 based.
HSSFRow row = sheet.createRow((short)0);
// Create a cell and put a date value in it. The first cell is not styled
// as a date.

cell.setCellValue(new Date());
// we style the second cell as a date (and time). It is important to
// create a new cell style from the workbook otherwise you can end up
// modifying the built in style and effecting not only this cell but other cells.

cellStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("m/d/yy h:mm"));

Seasar гэж юу вэ?
Seasar нь Япончуудын гаргасан Web Application Framework юм.Seasar-ийн онцлог
- Open Source програм хангамж
- Цэвэр JAVA технологи
- DI Container + AOP
- "See" "Sir" гэсэн үгээс бүтсэн
- Yasuo Higa гэдэг хүн Seasar-ийг бүтээжээ.
Seasar-ийн зорилго
- J2EE-ийн хамгийн сайн хэсгүүдийг авч J2EE-ийг ахин бүтээх
Seasar-ийн түүх
- 2001- 2002 онд бэлтгэл Seasar
- 2002 - 2003 онд анхны Seasar-ийн хувилбар гарсан(S0). StarLogic компани Tomcat болон iBATIS технологиудыг ашиглаж онлайн гадаад валют солих систем хөгжүүлсэн.
- 2003 онд Seasar1 хувилбар гарсан. J2EE Server-т Flowlet, Rulet, Sqlet, Jetty, HSQLDB, GPSS, Eclipse plugin бүгд агуулагдсан.
- 2004 оны 4 сард Seasar2 гарсан. DI Container нь DI-ийн хуучин функцуудыг ахин build хийх замаар хөгжүүлэгдсэн.
Дотроо олон хэсгүүдтэй ба тэдгээрээс өргөн хэрэглэгддэг S2Container(DI Container), S2Dao, S2JSF-ийн талаар бага ч гэсэн ойлголтуудыг өгөх болно.
