需要引入java-unrar-0.3.jar 和 commons-logging-1.1.1.jar

package com.test;
    import java.io.File;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import de.innosystec.unrar.Archive;
    import de.innosystec.unrar.exception.RarException;
    import de.innosystec.unrar.rarfile.FileHeader;
    
    public class RARUtil {
    	
    	public  static void unrar(String srcPath,String unrarPath) throws RarException, IOException{
    		unrar(new File(srcPath), unrarPath);
    	}
    	
    	public  static void unrar(File srcFile,String unrarPath) throws RarException, IOException{
    		if(null == unrarPath || "".equals(unrarPath)){
    			unrarPath = srcFile.getParentFile().getPath();
    		}
    		System.out.println("unrar file to :"+unrarPath);
            FileOutputStream fileOut;
            File file;    
            Archive rarfile = new Archive(srcFile);
            FileHeader entry = rarfile.nextFileHeader();
            while(entry!=null){
            	
            	String entrypath = "";
            	if(entry.isUnicode()){//解決中文乱码
            		entrypath = entry.getFileNameW().trim();
            	}else{
            		entrypath = entry.getFileNameString().trim();  
            	}
    
            	entrypath=entrypath.replaceAll("\\\\", "/");
            	
            	file = new File(unrarPath+"/"+entrypath);
            	System.out.println("unrar entry file :"+file.getPath());
            	if(entry.isDirectory()){
            		file.mkdirs();
            	}else{
                	File parent = file.getParentFile();
                    if(parent!=null && !parent.exists()){
                        parent.mkdirs();
                    }
                    fileOut = new FileOutputStream(file);
                    rarfile.extractFile(entry, fileOut);
                    fileOut.close();
            	}        	
            	entry = rarfile.nextFileHeader();
            }
            rarfile.close();
            
    	}
    
    
    }
