如何解决时区和SSL问题 [英] How can i fix the problem with timezone and SSL

问题描述

如果我的应用程序属性如下:

If my application properties look like this:

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

我得到一个错误:

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.

如果我更改:

spring.datasource.url=jdbc:mysql://localhost:3306/employees?useSSL=false

收件人:

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?

推荐答案

我有错误的依赖项，因为:

I had wrong dependency becouse:

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

需要此依赖项:

        <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>8.0.15</scope>
    </dependency>

我的版本是8.0.11

i had version 8.0.11

时区问题已通过以下行得到解决:

The problem with the time zone has been solved by this line:

spring.datasource.url=jdbc:mysql://localhost:3306/yourTableName?useLegacyDatetimeCode=false&serverTimezone=UTC
