springboot和sqlite 集成虑绵，由于是Hibernate5尿瞭，不能用現(xiàn)成的com.enigmabridge hibernate4-sqlite-dialect方言包，需要自己配置

gradle

runtime('org.xerial:sqlite-jdbc')

或者 maven

<!-- SQLite3 驅(qū)動(dòng) -->
        <dependency>
            <groupId>org.xerial</groupId>
            <artifactId>sqlite-jdbc</artifactId>
            <version>3.20.0</version>
        </dependency>

application.yml

database-platform 是自己寫(xiě)的配置類翅睛，hibernate的方言配置

spring: 
  datasource:
    driver-class-name: org.sqlite.JDBC
    url: jdbc:sqlite:F:\\db\\sqlite\\db.db
    username:
    password:
### sqlite需要自己配置連接方式
