Java使用AES/CBC/PKCS7Padding时会报错，因为原生JDK不支持。
修改方法很简简单单，两步：
1、添加算法的jar包bcprov-jdk16-1.46.jar
2、配置使jar包生效

添加jar包

下载bcprov-jdk16-1.46.jar

添加到jdk目录jdk_path/jre/lib/ext

配置生效

修改jdk_path/jre/lib/security/java.security

security.provider.3=sun.security.ec.SunEC
security.provider.4=com.sun.net.ssl.internal.ssl.Provider
security.provider.5=com.sun.crypto.provider.SunJCE
security.provider.6=sun.security.jgss.SunProvider
#security.provider.7=com.sun.security.sasl.Provider   #注释这一行
security.provider.7=org.bouncycastle.jce.provider.BouncyCastleProvider #添加这一行
security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI

OK，完事！
