Cannot find any provider supporting AES/CBC/PKCS7Padding

AES（128位）加密出现

java.security.NoSuchAlgorithmException: Cannot find any provider supporting AES/CBC/PKCS7Padding

引入bcprov-ext-jdk16 jar包

<dependency><groupId>org.bouncycastle</groupId><artifactId>bcprov-ext-jdk16</artifactId><version>1.46</version>
</dependency>

bcprov-jdk16好像也行

并且在代码中加入

static {Security.addProvider(new BouncyCastleProvider());
}

如：

public class AESUtil {//util类私有化private AESUtil(){}static {Security.addProvider(new BouncyCastleProvider());}...
}

如果是256位的加密

java本身不支持 需要下载jce_policy-8.zip替换原java的jce jar包
