  • Spring Boot下使用JPA报错:’hibernate.dialect’ not set的解决办法
    版本问题,我的配置文件Application.yml,文件中添加
    database-platform: org.hibernate.dialect.MySQL5Dialect
  • Caused by: com.mysql.cj.core.exceptions.InvalidConnectionAttributeException: The server time zone…
    配置文件Application.yml中添加:serverTimezone=UTC
    其实这个不是spring boot + mybatis的问题, 其实是为了使MySQL JDBC驱动程序的5.1.33版本与UTC时区配合使用,必须在连接字符串中明确指定serverTimezone。
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?characterEncoding=utf-8&useSSL=false&autoReconnect=false&rewriteBatchedStatements=true&serverTimezone=UTC
    username: root
    password: 111
  jpa:
    database: mysql
    show-sql: true
