springboot+mysql+ SSLHandshakeException: No appropriate protocol is disabled cipher+state 08S01

springboot2 +druid + mysql JDBC异常信息：

信息一：JDBC 链接失败

com.alibaba.druid.pool.DruidDataSource$CreateConnectionThread.run(DruidDataSource.java:2840) - create connection SQLException, url: jdbc:mysql://mysql.config.:3306/zsyy-pt?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true, errorCode 0, state 08S01

信息二 ： No appropriate protocol (protocol is disabled or cipher suites are inappropriate) 不合适的协议， 协议是禁用或者 加密协议不恰当。

Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
at sun.security.ssl.HandshakeContext.(HandshakeContext.java:171) ~[?:1.8.0_292]

解决方法：
JDBC URL:

添加&useSSL=false

spring.datasource.druid.url=${U_JDBC_URL}?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true&useSSL=false
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.driver-class-name=com.mysql.jdbc.Driver
