rar的只能用第三方api，比如junrar
通过Java来读取UOS格式的国产文档的话，是有API可以来读取的，你可以通过Maven仓库来在下载spire.xls.jar, 在pom.xml中配置依赖：<repositories>
<repository>
<id>com.e-iceblue</id>
<name>e-iceblue</name>
<url>
</repository></repositories>
<dependencies>
<dependency>
<groupId>e-iceblue </groupId>
<artifactId>spire.xls</artifactId>
<version>12.7.4</version>
</dependency>
</dependencies>
不好意思搞反了，这样就更简单了。用这个构造方法ZipInputStream(InputStream in)接收传过来的流，然后用这个类的getNextEntry()方法解压缩文件，最后调用read(byte[] b, int off, int len)方法将数据写入byte数组。
ZipInputStream zin = new ZipInputStream(in)
ZipEntry entry = null
while((entry=zin.getNextEntry())!=null){
if(entry.isDirectory()||entry.getName().equals("..\\"))
continue
BufferedInputStream bin = new BufferedInputStream(zin)
byte[] buf = new byte[]
bin.read(buf,0,1)
}
