Java按年月日创建文件夹

import java.io.File;
import java.util.Calendar;
import org.apache.struts2.ServletActionContext; 
private static final Logger logger = Logger.getLogger(PictureAction.class);

 

按年月创建文件夹： 

 

Calendar cad = Calendar.getInstance();
		String month=String.valueOf(cad.get(Calendar.MONTH) + 1);
		if(month.length()<2){
			month=0+month;
		}
		//相对存放路径		
		String savePath = "/upload/picture/"+String.valueOf(cad.get(Calendar.YEAR))+ month;
		try {
			File dirFile = new File(ServletActionContext.getServletContext().getRealPath(savePath));
			boolean bFile = dirFile.exists();
			if (bFile == true) {
				//The folder exists.
			} else {
				//The folder do not exist,now trying to create a one.
				bFile = dirFile.mkdir();
				if (bFile == true) {
					//Create successfully!
				} else {
					//Disable to make the folder,please check the disk is full or not.
					logger.error("[java]PictureAction create folder is error,because Disable to make the folder,please check the disk is full or not.");
				}
			}
		} catch (Exception err) {
			logger.error("[java]PictureAction create folder is error,because the disk is full or not.", err);
		}
