java - 如何解决时区和 SSL 的问题
问题描述
如果我的应用程序属性如下所示:
server.port=8080
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/employees?useSSL=false
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
我收到一个错误:
java.sql.SQLException: The server time zone value 'rodkowoeuropejski czas stand' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
如果我改变:
spring.datasource.url=jdbc:mysql://localhost:3306/employees?useSSL=false
到:
spring.datasource.url = jdbc:mysql://localhost:3306/CityBikeRental?useLegacyDatetimeCode=false&serverTimezone=UTC
我明白了:
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.
有人可以帮助我吗?
解决方案
我有错误的依赖,因为:
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
需要这个依赖:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>8.0.15</scope>
</dependency>
我有版本 8.0.11
时区问题已通过此行解决:
spring.datasource.url=jdbc:mysql://localhost:3306/yourTableName?useLegacyDatetimeCode=false&serverTimezone=UTC
