好像没有办法枚举某个目录下的ZipEntry

您必须遍历所有 ZipFile.entries()并根据 ZipEntry.getName() 筛选您想要的那些看看是不是String.startsWith(String prefix) .

String specificPath = "some/path/in/zip/";

ZipFile zipFile = new ZipFile(file);
Enumeration<? extends ZipEntry> entries = zipFile.entries();
while (entries.hasMoreElements()) {
    ZipEntry ze = entries.nextElement();
    if (ze.getName().startsWith(specificPath)) {
        System.out.println(ze);
    }
}
