使用POI的hwpf操作word乱码

public void testWord(String file,String newPath) {

		//File file = new File(fileString);

		try {

			FileInputStream in = new FileInputStream(file);

			POIFSFileSystem pfs = new POIFSFileSystem(in);

			HWPFDocument hwpf = new HWPFDocument(pfs);

			Range range = hwpf.getRange();

			StyleSheet styleSheet = hwpf.getStyleSheet();

			TableIterator it = new TableIterator(range);

			// 遍历一个DOC中的所有表格

			while (it.hasNext()) {

				Table tb = (Table) it.next();

				// 遍历表格的行

				for (int i = 0; i < tb.numRows(); i++) {

					TableRow tr = tb.getRow(i);

					// 遍历表格的列

					for (int j = 0; j < tr.numCells(); j++) {

						// 往表格中插入数据

						TableCell td = tr.getCell(j);

						String text = "哈哈，输入中文";

						int p = td.numParagraphs();

						Paragraph para = td.getParagraph(p);

						ParagraphProperties pp = new ParagraphProperties();

						if(j%2==0){

							para.insertBefore(text);

						}

					}

				}

			}

			// 在表格外面插入内容

			CharacterProperties cp = new CharacterProperties();

			cp.setBold(true);

			cp.setCharacterSpacing(10);

			cp.setChse(cp.SPRM_CHARSCALE);

			cp.setCapitalized(true);

			File outputFile = new File(newPath);

			OutputStream output = new FileOutputStream(outputFile);

			hwpf.write(output);

			output.close();

			

		} catch (Exception ex) {

			ex.printStackTrace();

		}
