spring boot连接mysql8.0

今天spring boot的项目数据库从mysql5.7换到mysql8.0，遇到点问题，特此记录下来

查看mysql的版本

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.12 |
+-----------+

修改mysql的依赖使用MySQL Connector/J

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.</version>
</dependency>

数据源配置

# 数据源配置，请修改为实际配置
spring.datasource.url=jdbc:mysql://localhost:3306/bim?serverTimezone=Asia/Shanghai&zeroDateTimeBehavior=convertToNull&autoReconnect=true&useSSL=false&failOverReadOnly=false
spring.datasource.username=bimengine
spring.datasource.password=fgBQLZpgDaxH7xuu
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

项目启动如果报错

java.sql.SQLException: The connection property 'zeroDateTimeBehavior' acceptable values are: 'CONVERT_TO_NULL', 'EXCEPTION' or 'ROUND'. The value 'convertToNull' is not acceptable.

修改数据源配置

# 数据源配置，请修改为实际配置
spring.datasource.url=jdbc:mysql://localhost:3306/bim?serverTimezone=Asia/Shanghai&zeroDateTimeBehavior=CONVERT_TO_NULL&autoReconnect=true&useSSL=false&failOverReadOnly=false
spring.datasource.username=bimengine
spring.datasource.password=fgBQLZpgDaxH7xuu
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

如果报错

java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowe

连接数据库的url中，加上allowPublicKeyRetrieval=true参数
