org.jasypt.exceptions.EncryptionOperationNotPossibleException 抛出 HTTP 状态 500

Question

我正在检查字符串是否未加密然后显示消息但它抛出 HTTP Status 500 – Internal Server Error 如下：

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)

这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;
    }
}

如果字符串未解密，我会尝试显示我的消息

        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()));
        }

尽管显示 Message.getExpired() 为什么它会抛出 HTTP Status 500 – Internal Server Error？

Answer 1

我发现在以下情况下会抛出此错误：

String已经是Encrypted
当加密或解密时有白色space。所以 str.replaceAll(" ", "+"); 和 str.replaceAll("+", " "); 解决了这个问题
