springboot ZIP压缩目录,并切保证全是的目录结构

你可以使用Java中提供的ZipOutputStream类来实现对目录的压缩。以下是一个使用Spring Boot实现的示例代码:
```java
@RestController
public class ZipController {
@GetMapping("/zip")
public void zipDirectory(HttpServletResponse response) throws IOException {
File directoryToZip = new File("path/to/directory");
List<File> fileList = new ArrayList<>();
getAllFiles(directoryToZip, fileList);
byte[] buffer = new byte[1024];
try (ZipOutputStream zos = new ZipOutputStream(response.getOutputStream())) {
for (File file : fileList) {
String filePath = file.getCanonicalPath();
String entryName = filePath.substring(directoryToZip.getCanonicalPath().length() + 1);
ZipEntry zipEntry = new ZipEntry(entryName);
zos.putNextEntry(zipEntry);
try (FileInputStream fis = new FileInputStream(file)) {
int length;
while ((length = fis.read(buffer)) > 0) {
zos.write(buffer, 0, length);
}
}
zos.closeEntry();
}
}
response.setStatus(HttpServletResponse.SC_OK);
response.addHeader("Content-Disposition", "attachment; filename=\"directory.zip\"");
}
private void getAllFiles(File dir, List<File> fileList) {
File[] files = dir.listFiles();
for (File file : files) {
fileList.add(file);
if (file.isDirectory()) {
getAllFiles(file, fileList);
}
}
}
}
```
在这个示例中,我们首先获取要压缩的目录(`directoryToZip`),然后遍历目录中的所有文件和子目录,并将它们加入到一个文件列表中。接下来,我们使用ZipOutputStream类创建一个zip文件,并将列表中的所有文件写入到zip文件中。最后,我们设置响应头,指定下载的文件名为`directory.zip`,并将zip文件下载到客户端。
需要注意的是,在上面的代码中,我们使用`getAllFiles()`方法遍历了目录中的所有文件和子目录。这是为了保证压缩后的zip文件中包含了原目录的所有子目录结构。
