相关疑难解决方法(0)

使用tomcat,我有两个web应用程序,即app1和app2.我将app1以加密形式(使用下面的代码)发送到app2.然后在app2我解密了这个加密的网址.但是我在decryp方法的第50行低于例外.

虽然我尝试在app1解密(使用相同代码)加密的URL时进行调试,但它工作正常.但无法弄清楚在app2引起此异常的原因是什么？

这是代码

import java.security.Key;

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class AESEncryptionDecryptionTest {

    private static final String ALGORITHM       = "AES";
    private static final String myEncryptionKey = "ThisIsFoundation";
    private static final String UNICODE_FORMAT  = "UTF8";

    public static String encrypt(String valueToEnc) throws Exception {
        Key key = generateKey();
        Cipher c = Cipher.getInstance(ALGORITHM);
        c.init(Cipher.ENCRYPT_MODE, key);  
        byte[] encValue = c.doFinal(valueToEnc.getBytes());
        String encryptedValue = new …
