Shiro New String ((char[)) token.getcredentials ()), and Token.getcredentials (). toString (); the difference _shiro

String password = new string ((char[)) token.getcredentials ());

Above: This can pass the test normally.

String password = token.getcredentials (). toString ();

Error:

Test code:

Public AuthenticationInfo Getauthenticationinfo (Authenticationtoken token)
			throws Authenticationexception {
		String username = Token.getprincipal (). toString ();
		String password = new string ((char[)) token.getcredentials ());
		System.out.println (Token.getcredentials ());

		SYSTEM.OUT.PRINTLN (password);
		System.out.println ("----------------");
		String password2 = Token.getcredentials (). toString ();
		System.out.println (Token.getcredentials ());
		System.out.println (PASSWORD2);
		
		if (! () Zhangsan ". Equals (username))) {
			throw new unknownaccountexception ();

		if (! () 123 ". Equals (password))) {
			throw new incorrectcredentialsexception ();

		return new Simpleauthenticationinfo (username, password, getName ());
