MySQL - L'établissement d'une connexion SSL sans vérification d'identité du serveur n'est pas recommandé
Démarrez une application Spring Boot et établissez une connexion JDBC, affiche les messages d'avertissement suivants sur la console:
Fri Feb 10 18:43:02 SGT 2017 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. //... repeat over and over
Voici les propriétés de connexion:
application.properties
#mysql datasource spring.datasource.url=jdbc:mysql://localhost/example spring.datasource.username=root spring.datasource.password=password spring.datasource.driver-class-name=com.mysql.jdbc.Driver
P.S Tested with MySQL 5.7.17
Solution
Pour résoudre ce problème, ajoutez unuseSSL=false à la fin de la chaîne de connexion MySQL:
application.properties
#mysql datasource spring.datasource.url=jdbc:mysql://localhost/example?useSSL=false spring.datasource.username=root spring.datasource.password=password spring.datasource.driver-class-name=com.mysql.jdbc.Driver
