java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
SSL证书问题
出现此错误信息时解决办法：
找到jre路径：JDK_HOME/jre/lib/security/java.security 或JDK目录下的JRE
找到内容：jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
把此行注释掉如：
#jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024
搞定！！！
