Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

jdbc url 后面增加参数 useSSL=false 即可
```
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/imooc-demo?useUnicode=true&characterEncoding=UTF-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=123456
```
No Spring Session store is configured: set the 'spring.session.store-type' property
```
spring.session.store-type=none
```
org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

需要安装并配置 redis 服务器参数
```
spring.redis.host=127.0.0.1
spring.redis.port=6379
```
需要进行身份验证
```
security.basic.enabled=false
```
