我编写了一个带有Field LoginId和Password的权限类.
Iam使用AES_ENCRYPT加密passwrd并在db中加载它.
我想只检索解密的密码.所以,我在OPen JPA 2.0中使用NAEDQueryis使用AES_DECRYPT.
我写的查询是:
Query q = em.createNativeQuery("select AES_DECRYPT(l.password,?2) from loginDetails l where l.loginID = ?1");
q.setParameter(1, loginId);
q.setParameter(2, getKey());
String s = q.getSingleResult();
但我得到以下例外:
java.lang.ClassCastException: [B cannot be cast to java.lang.String

我甚至试过这个:
