java - org.springframework doesn't contain CIpher

Question

I want to import cipher from org.springframework dependency. I have imported it like below,

import org.springframework.security.crypto.keygen.KeyGenerators;
import org.springframework.security.crypto.encrypt.CipherUtils.Cipher;
import org.springframework.security.crypto.encrypt.SecretKey;

but there's an error throwing saying that,

Error:(25,63) java: package org.springframework.security.crypto.encrypt.CipherUtils does not exist

Then I tried

import org.springframework.security.crypto.keygen.KeyGenerators;
import org.springframework.security.crypto.encrypt.Cipher;
import org.springframework.security.crypto.encrypt.SecretKey;

I still get the below error,

Error:(25,51) java: cannot find symbol

I want cipher to use encryption and decryption of my otp and expiry date. How can I import cipher from org.springframework

Answer 1

类org.springframework.security.crypto.encrypt.CipherUtils不包含内部类Cipher，包org.springframework.security.crypto.encrypt也不包含类Cipher。

类org.springframework.security.crypto.encrypt.CipherUtils 使用javax.crypto.Cipher类，你也必须使用这个类。

Answer 2

错误：（25,63）java：包 org.springframework.security.crypto.encrypt.CipherUtils 不存在

您收到此错误是因为 CipherUtils 是一个类。

如果您想使用import org.springframework.security.crypto.encrypt.CipherUtils;此类，请使用。

错误：（25,51）java：找不到符号

您收到此错误是因为您的密码在此处不存在

import org.springframework.security.crypto.encrypt.Cipher;.

利用import javax.crypto.Cipher;
