思路：
1.得到需要壓縮的文件列表。
2.壓縮生成zip文件。
3.刪除原始文件。
4.返回zip文件路徑。

不廢話，直接上代碼：
public String getZipFile(){String filePath = "D:/";
String zipFileName = "D:/test/test.zip";
File file = new File(filePath);
List<String> files = new ArrayList<>;
//獲取文件列表,此處省略
File zipFile = new File(zipFileName);
File fileParent = zipFile.getParentFile();
if(!fileParent.exists()){
fileParent.mkdirs();
}
exportZip(files,zipFile);
return zipFileName;
}
**
* 打包成zip
* @param fileNames
* @param zip
* @throws FileNotFoundException
* @throws IOException
*/
private void exportZip( List<String> fileNames, File zip) throws FileNotFoundException {
//1.壓縮文件
File srcFile[] = new File[fileNames.size()];
for (int i = 0; i < fileNames.size(); i++) {
srcFile[i] = new File(fileNames.get(i));
}
byte[] byt = new byte[1024];
ZipOutputStream out = null;
FileInputStream in = null;
try {
out = new ZipOutputStream(new FileOutputStream(zip), Charset.forName(CHARACTOR_CODE));
for (int i = 0; i < srcFile.length; i++) {
try{
in = new FileInputStream(srcFile[i]);
out.putNextEntry(new ZipEntry(srcFile[i].getName()));
int length;
while((length=in.read(byt)) > 0){
out.write(byt,0,length);
}
out.closeEntry();
in.close();
}catch (Exception e){
LOGGER.info("文件打包失敗:{}",e);
}finally{
try{
in.close();
}catch (Exception e1){
LOGGER.info("文件流關閉失敗：{}",e1);
}
}
}
out.close();
} catch (Exception e) {
LOGGER.info("文件打包失敗，{}",e);
throw new FileNotFoundException();
}finally {
try {
out.close();
in.close();
} catch (IOException e) {

}
}
//2.刪除服務器上的臨時文件(excel)
for (int i = 0; i < srcFile.length; i++) {
File temFile = srcFile[i];
if(temFile.exists() && temFile.isFile()){
try{
temFile.delete();
}catch(Exception e){
