使用Spring Boot连接mysql数据库,配置application.properties文件时使用了如下URL
spring.datasource.url=jdbc:mysql://localhost:3306/toutiao?useUnicode=true&characterEncoding=utf8&useSSL=false
运行的时候报了警告:
WARN: 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.
网上搜索的答案都是在url后面加上useSSL=true或者false;但是我本来就已经有了。
尝试了许久,发现只要把url中的&换成&就好了。如下:
spring.datasource.url=jdbc:mysql://localhost:3306/toutiao?useUnicode=true&characterEncoding=utf8&useSSL=false
具体是什么原因不清楚。
