sqlite資料庫方言配置

標籤：

1. application.properties配置sqlite資料庫

spring.datasource.url = jdbc:sqlite:C:/test/sqlite/DB/sqlite.dbspring.datasource.driverClassName = org.sqlite.JDBCspring.jpa.database = SQLitespring.jpa.show-sql = truespring.jpa.hibernate.ddl-auto = updatespring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategyspring.jpa.properties.hibernate.dialect = test.utils.SQLiteDialectmultipart.maxFileSize=10Mb

2. 本地添加方言檔案
