java获取工程目录路径

public class PathUtil {

     PathUtil pathUtil = new PathUtil();
     System.out.println(p.getWebClassesPath());
     System.out.println(p.getWebInfPath());
     System.out.println(p.getWebRoot());
   }

//获取当前文件路径

   public String getWebClassesPath() {
     String path = getClass().getProtectionDomain().getCodeSource()

     return path;
   }

//获取当前工程的web-inf路径

   public String getWebInfPath() throws IllegalAccessException{
     String path = getWebClassesPath();
     if (path.indexOf("WEB-INF") > 0) {
      path = path.substring(0, path.indexOf("WEB-INF")+8);
     } else {
      throw new IllegalAccessException("路径获取错误");
