微信红包报错：No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

网上查阅资料，都说在Java8及高版本以上的版本在调用ssl时会出现javax.net.ssl.SSLHandshakeException: No appropriate protocol的异常。

解决办法如下：

修改jre/lib/security/java.security中的disabledAlgorithms，删除SSLv3, TLSv1, TLSv1.1，然后重启应用即可。

修改后：

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

果然问题完美解决
