错误原因：

jdk版本问题

笔者使用的jdk版本为1.8.0_301

/Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home/jre/lib/security/java.security

java.security文件内容

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

解决办法

办法一：删除掉java.security文件中的SSLv3, TLSv1, TLSv1.1

办法二：更换jdk版本
