导出word并实现换行

代码如下:

注:为进行main方法测试,所以方法都定义成static的

1.获取要写入word的数据(以字符串进行拼接)

public static StringBuilder getContent(File file, StringBuilder sb) {

//添加文本

    FileInputStream fis =null;

try {

fis =new FileInputStream(file);

InputStreamReader reader =new InputStreamReader(fis,"utf-8");

BufferedReader br =new BufferedReader(reader);

String readLine = br.readLine();

while (readLine !=null) {

if (readLine.contains("package") || readLine.contains("import") || (readLine.contains("public") && readLine.contains("class")) || readLine.contains("\\\\")

|| readLine.trim().equals("") || readLine.contains("*")

) {

readLine = br.readLine();

continue;

}else {

if (readLine.length() >133) {

String substring0 = readLine.substring(0,133);

String substring1 = readLine.substring(133);

sb.append(line.incrementAndGet() +"." + substring0 +"\n\r");

sb.append(line.incrementAndGet() +"." + substring1 +"\n\r");

}else {

sb.append(line.incrementAndGet() +"." + readLine +"\n\r");

}

}

// sb.append(line.incrementAndGet() + ".  " + readLine + "\n\r");

            readLine = br.readLine();

}

if (br !=null) {

try {

br.close();

}catch (IOException e) {

e.printStackTrace();

}

}

}catch (FileNotFoundException e) {

e.printStackTrace();

}catch (UnsupportedEncodingException e) {

e.printStackTrace();

}catch (IOException e) {

e.printStackTrace();

}

return sb;

}

2.设置word相关格式

public static void getData(String sb)throws Exception {

XWPFDocument doc =new XWPFDocument();

XWPFParagraph para;

para = doc.createParagraph();

para.setAlignment(ParagraphAlignment.LEFT);//设置左对齐

    String[] split = sb.split("\n");

for (String s : split) {

XWPFRun run1;

run1 = para.createRun();

run1.setText(s);

run1.addCarriageReturn();

run1.setFontFamily("仿宋");

run1.setFontSize(13);

}

doc.createParagraph();

String path ="D:\\hello.docx";

OutputStream os =new FileOutputStream(path);

doc.write(os);

if (os !=null) {

try {

os.close();

System.out.println("文件已输出!");

}catch (IOException e) {

e.printStackTrace();

}

}

}

3.main方法进行测试

public static void main(String[] args)throws Exception {

File file0 =new File("D:\\GitCode\\hello");

File[] files = file0.listFiles();

StringBuilder sb =new StringBuilder();

for (File file : files) {

int andIncrement =atomicInteger.getAndIncrement();

if (andIncrement <20) {

getContent(file, sb);

}

}

getData(sb.toString());

}

4.用于计数的相关属性

static AtomicIntegeratomicInteger =new AtomicInteger(0);

static AtomicIntegerline =new AtomicInteger(0);
