请问断点续传的代码在哪体现啊？

cn.attackme.myuploader.utils.FileUtils
public static void writeWithBlok(String target, Long targetSize, InputStream src, Long srcSize, Integer chunks, Integer chunk) throws IOException {
RandomAccessFile randomAccessFile = new RandomAccessFile(target,"rw");
randomAccessFile.setLength(targetSize);
if (chunk == chunks - 1 && chunk != 0) {
randomAccessFile.seek(chunk * (targetSize - srcSize) / chunk);
} else {
randomAccessFile.seek(chunk * srcSize);
}
byte[] buf = new byte[1024];
int len;
while (-1 != (len = src.read(buf))) {
randomAccessFile.write(buf,0,len);
}
randomAccessFile.close();
}

RandomAccessFile，主要看这个类
randomAccessFile.seek()

流没有关闭，差点把服务器搞挂了

public static void writeWithBlok(String target, Long targetSize, InputStream src, Long srcSize, Integer chunks, Integer chunk) throws IOException {
RandomAccessFile randomAccessFile = new RandomAccessFile(target,"rw");
randomAccessFile.setLength(targetSize);
if (chunk == chunks - 1 && chunk != 0) {
randomAccessFile.seek(chunk * (targetSize - srcSize) / chunk);
} else {
randomAccessFile.seek(chunk * srcSize);
}
byte[] buf = new byte[1024];
int len;
while (-1 != (len = src.read(buf))) {
randomAccessFile.write(buf,0,len);
}
// 释放流,避免内存溢出
src.close();
randomAccessFile.close();
}

分块之后不合并的吗？

这断点续传没体现出来作用，大文件上传的Controller和writeWithBlok方法都是返回void，想问下前端怎么知道哪个分片没上传成功需要重传？
