我已經(jīng)構(gòu)建了一個 ESAPITestValidator 類，如下所示：public class ESAPITestValidator {Validator instance = ESAPI.validator();ValidationErrorList errors = new ValidationErrorList();File parent = null;String path = new String("");boolean status = false;public boolean testGetValidDirectoryPath(String inputPath,String context)   {     try     {        parent = new File(inputPath).getParentFile().getCanonicalFile();        //String parent = ESAPI.securityConfiguration().getResourceFile("ESAPI.properties").getParentFile().getCanonicalPath();        path = instance.getValidDirectoryPath(context, inputPath, parent, true, errors);        status = true;        return status;     }catch(Exception exception)     {         exception.printStackTrace();         status= false;       }     return status; }}現(xiàn)在我正嘗試從主類調(diào)用 testGetValidDirectoryPath() ，如下所示：public class HelloWorld {public static void main(String[] args) {    ESAPITestValidator obj =  new ESAPITestValidator();    if ( obj.testGetValidDirectoryPath("C:\\Users\\1730176\\Downloads","C:\\Users") )      System.out.println("Success");    else      System.out.println("Failure");         }}
