java解压rar文件的代码,依赖是

在Java中解压RAR文件通常会使用第三方库,比如`java-unrar`或者` Commons compression library (commons-compress)`。以下是使用`java-unrar`库的一个简单示例:
```java
import com.github.rjeschke.txtmark.TextMark;
import org.jetbrains.rar.RarEntry;
import java.io.*;
public class UnrarExample {
public static void main(String[] args) throws IOException, RarException {
// 导入所需的RAR处理库
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
URL unrarURL = classLoader.getResource("java-unrar.jar");
File unrarJar = new File(unrarURL.getFile());
// 使用类加载器加载jar并获取UnrarEngine实例
TextMark text = new TextMark();
UnrarEngine engine = UnrarEngine.create(text);
// 指定RAR文件路径和提取目录
String.rarFilePath = "path_to_your_rar_file";
String.extractDirPath = "path_to_extract_directory";
// 打开RAR文件并开始解压
try (BufferedInputStream input = new BufferedInputStream(new FileInputStream(rarFilePath));
UnrarReader reader = new UnrarReader(input)) {
while (reader.next()) {
RarEntry entry = reader.getEntry();
if (!entry.isDirectory()) {
// 创建目标文件
File outputFile = new File(extractDirPath + File.separator + entry.getName());
try (OutputStream output = new FileOutputStream(outputFile)) {
// 写入内容
reader.readTo(output);
}
}
}
} finally {
// 关闭资源
engine.close();
}
}
}
```
确保将`java-unrar.jar`文件放在项目的类路径下,并替换`rarFilePath`和`extractDirPath`为实际的RAR文件路径和目标解压目录。
