sqlite数据库方言配置

1. application.properties配置sqlite数据库

spring.datasource.url = jdbc:sqlite:C:/test/sqlite/DB/sqlite.db
spring.datasource.driverClassName = org.sqlite.JDBC
spring.jpa.database = SQLite
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = test.utils.SQLiteDialect
multipart.maxFileSize=10Mb

2. 本地添加方言文件
