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);
