org.jasypt.exceptions.EncryptionOperationNotPossibleException抛出HTTP状态500

Question

我正在检查字符串是否加密，然后显示消息，但其抛出的HTTP Status 500 – Internal Server Error如下所示：

org.jasypt.exceptions.EncryptionOperationNotPossibleException
    org.jasypt.encryption.pbe.StandardPBEByteEncryptor.decrypt(StandardPBEByteEncryptor.java:1055)
    org.jasypt.encryption.pbe.StandardPBEStringEncryptor.decrypt(StandardPBEStringEncryptor.java:725)
    parvaz.aero.commons.security.Encryptor.decrypt(Encryptor.java:64)
    parvaz.aero.registration.staff.reset.ResetPassword.doGet(ResetPassword.java:34)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:626)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:733)
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53)

下面是我检查字符串是否加密的方法

public static boolean isStringEncrypted(String str) {
    try {
        decrypt(str);
        return false;
    }catch(Exception e) {
        return true;
    }
}

在这里，如果字符串没有解密，我将尝试显示我的消息。

        if(!isTokenNull) {
            String resetTokenEmail      = Encryptor.decrypt(resetToken);
            boolean isEmailEncrypted    = Encryptor.isStringEncrypted(resetTokenEmail);
        
            if(isEmailEncrypted) {
                String form = ChangePasswordForm.displayForm(resetToken,"","");
                out.println(SiteTemplate.webPage(form));
            }
            else {
                out.println(SiteTemplate.webPage(Message.getExpired()));
            }
        }
        else {
            out.println(SiteTemplate.webPage(Message.getExpired()));
        }

尽管向Message.getExpired()展示了其抛出HTTP Status 500 – Internal Server Error的原因

我发现在以下情况下引发此错误：

Encrypted

• When已经是，String在加密或解密时有空白。所以str.replaceAll(" ", "+");和str.replaceAll("+", " ");解决了这个问题
