Question

以下是我的Encryptor类方法：

    public String encrypt(String str){ 
        if(str == null || str.equals("")){
            str = "";
        }
        else{
            StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
            encryptor.setPassword(mpCryptoPassword);
            str = encryptor.encrypt(str);
        } 
    return str;
    }
    public String decrypt(String str){
        if(str == null || str.equals("")){
            str = "";
        }
        else{
            StandardPBEStringEncryptor decryptor = new StandardPBEStringEncryptor();
            decryptor.setPassword(mpCryptoPassword);
            str = decryptor.decrypt(str);
        }
    return str;
    }

我正在尝试加密如下：

String encryptedToken   = "";
//preparing token email + time
Date now            = new Date();               
String prepareToken = "email="+email+"&tokenTime="+now.getTime();

//encrypt url value
Encryptor enc       = new Encryptor();
encryptedToken      = enc.encrypt(prepareToken);

我正在解密：

Encryptor enc           = new Encryptor();
String decryptedToken   = enc.decrypt(encryptedToken);

然后它的投掷错误：

org.jasypt.exceptions.EncryptionOperationNotPossibleException at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.decrypt（StandardPBEByteEncryptor.java:1055） at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.decrypt（StandardPBEStringEncryptor.java:725）在com.cryptography.Encryptor.decrypt（Encryptor.java:57）在com.users.forgot.ResetPassword.doGet（ResetPassword.java:72）在javax.servlet.http.HttpServlet.service（HttpServlet.java:622）在javax.servlet.http.HttpServlet.service（HttpServlet.java:729）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:290）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206） at filters.charsetFilter.filter.CharsetFilter.doFilter（CharsetFilter.java:61）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:235）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:206）在org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:233） at org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:191）在org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:128） at org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:102）在org.apache.catalina.core.StandardEngineValve.invoke（StandardEngineValve.java:109）在org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:286）在org.apache.coyote.http11.Http11Processor.process（Http11Processor.java:845）在org.apache.coyote.http11.Http11Protocol $ Http11ConnectionHandler.process（Http11Protocol.java:583）在org.apache.tomcat.util.net.JIoEndpoint $ Worker.run（JIoEndpoint.java:447）在java.lang.Thread.run（Thread.java:744）

更新
我注意到它的工作有时但是当加密字符串中有+符号作为其获取+作为空间

时不工作

Answer 1

我发现的问题是加号字符串加号+。当我解密时，它从URL获取+作为空白区域。

encryptedToken = encryptedToken.replaceAll(" ","+");

解决这个问题

为什么org.jasypt.exceptions.EncryptionOperationNotPossibleException
