javaFile和Byte数组相互转换

public static void main(String[] args){
String filePath = "E:\\softoon\\workspace_softoon\\TestMobile\\src\\1.docx";
String outFilePath = "E:\\softoon\\workspace_softoon\\TestMobile\\src";
String outFileName = "2.docx";
getFile(getBytes(filePath),outFilePath,outFileName);
// ----------------获得指定文件的byte数组 ----------------

try {
File file = new File(filePath);
FileInputStream fis = new FileInputStream(file);
ByteArrayOutputStream bos = new ByteArrayOutputStream(1000);
byte[] b = new byte[1000];
int n;
while ((n = fis.read(b)) != -1) {
bos.write(b, 0, n);
fis.close();
bos.close();
buffer = bos.toByteArray();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
return buffer;
// ----------------根据byte数组，生成文件 ----------------
