javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher su 解决办法

一、发现问题

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
	at sun.security.ssl.HandshakeContext.<init>(HandshakeContext.java:171)
	at sun.security.ssl.ClientHandshakeContext.<init>(ClientHandshakeContext.java:98)
	at sun.security.ssl.TransportContext.kickstart(TransportContext.java:220)

二、研究问题
jdk问题

三、解决问题
修改java.security 文件

Linux 默认路径/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.275.b01-1.el8_3.x86_64/jre/lib/security
Windows默认路径C:\Program Files\Java\jdk1.8.0_261\jre\lib\security

[root@iZ2ze30dygwd6yh7gu6lskZ security]# pwd
[root@iZ2ze30dygwd6yh7gu6lskZ security]# pwd
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.275.b01-1.el8_3.x86_64/jre/lib/security
[root@iZ2ze30dygwd6yh7gu6lskZ security]# ls
blacklisted.certs  cacerts  java.policy  java.security  nss.cfg  nss.fips.cfg  policy
[root@iZ2ze30dygwd6yh7gu6lskZ security]#

删除SSLv3, TLSv1, TLSv1.1

重启您的Java服务即可

如果仍然报错那就使用下面的方法
把 “TLSv1” 给改成null
把微信提供的方法中TLSv1改成null

SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(
                    sslContext,
//                    new String[]{"TLSv1"},    // 解决javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
                    null,
                    null,
                    new DefaultHostnameVerifier());

实在不行的话建议直接更换JDK。
