Question

我是java的新手，所以请原谅我愚蠢的问题

1）我的项目从netbeans 6转移到8

2）jdk从6u45移动到8u11

3）调试

后成功设置到新环境

出错：javax.crypto.IllegalBlockSizeException：最后一个块解密不完整

堆栈跟踪：

com.alstom.tsoft.controller.system.ParameterTablesController $ LoadOfflineWorker - [javax.crypto.CipherInputStream.getMoreData（CipherInputStream.java:121）， javax.crypto.CipherInputStream.read（CipherInputStream.java:192）， com.alstom.tsoft.crypto.CryptoManager.decryptString（CryptoManager.java:146）， com.alstom.tsoft.io.CryptedFieldReader.readField（CryptedFieldReader.java:58），

4）以前environment(jdk6 and netbeans 6)中从未发生过，这是项目中唯一的变化。

我们正在使用以下输入：

private static final String ALGO_TYPE = "AES";
private static final String ALGO_FULL_NAME = "AES/ECB/PKCS5Padding";
private static final String ALGO_PROVIDER = "BC";

public String encryptString(String input) throws NoSuchAlgorithmException,NoSuchProviderException,
       NoSuchPaddingException,InvalidKeyException,IOException {
    StringBuffer output = new StringBuffer();
    CipherInputStream cis = new CipherInputStream(
           new ByteArrayInputStream(input.getBytes()),
           getEncryptionCipher());                
    int b;
    while ( ( b = cis.read() ) != -1 ) {           
       String twoHexDigit = String.format("%1$02x",b);           
       //m_logger.info(":"+b+":"+twoHexDigit.toUpperCase());
       output.append(twoHexDigit.toUpperCase());
    }
    return output.toString();
}
//Dencryption
public String decryptString(String input) throws NoSuchAlgorithmException,NoSuchProviderException,
       NoSuchPaddingException,InvalidKeyException,IOException {       
    StringBuffer output = new StringBuffer();                        
    byte[] inputBytes = convertHexStringToByte(input);        

    CipherInputStream cis = new CipherInputStream(
           new ByteArrayInputStream(inputBytes), 
           getDecryptionCipher());                      
    int b;
    while ( ( b = cis.read() ) != -1 ) {
       output.append(new Character((char)b));
    }                                              
    return output.toString();
}

请告知我在哪里做错了以及如何调试

提前致谢
