springboot 项目报错，可能是数据库连接的问题

Question

java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:129) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:97) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:89) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:63) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:73) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:76) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:835) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.ConnectionImpl.(ConnectionImpl.java:455) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:240) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.mysql.cj.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:199) ~[mysql-connector-java-8.0.15.jar:8.0.15]at com.zaxxer.hikari.util.DriverDataSource.getConnection(DriverDataSource.java:136) ~[HikariCP-3.2.0.jar:na]at com.zaxxer.hikari.pool.PoolBase.newConnection(PoolBase.java:369) ~[HikariCP-3.2.0.jar:na]at com.zaxxer.hikari.pool.PoolBase.newPoolEntry(PoolBase.java:198) ~[HikariCP-3.2.0.jar:na]at com.zaxxer.hikari.pool.HikariPool.createPoolEntry(HikariPool.java:467) [HikariCP-3.2.0.jar:na]at com.zaxxer.hikari.pool.HikariPool.(HikariPool.java:115) [HikariCP-3.2.0.jar:na]

Answer 1

可以尝试一下
jdbc:mysql://localhost:3306/database?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
即最后设置时区：serverTimezone=GMTGMT%2B8（gmt+8时区）

Answer 2

控制台打印出了你报错的原因是因为你sql的问题：那么应该从这个方向去解决
1.是不是只有这一条SQL的执行出现了问题，如果是那么根据报错的原因可能是你时间转换的时候，转换成了sql不识别的时间格式，
所以时间格式对不上导致的报错，解决方向：百度Mysql/Oracle数据库时间查询语句
2.如果不是这条语句的问题那么应该是在你application的配置中关于时区或者时间相关的配置点出了错，那么你解决方向为：Spring Boot
时区格式设置/spring boot时间sql查询之类的
