首先在pom中引用Sqlite3访问驱动包

<!-- sqlite3驱动包 -->
<dependency>
    <groupId>org.xerial</groupId>
    <artifactId>sqlite-jdbc</artifactId>
    <version>3.27.2.1</version>
</dependency>

在yml中配置Sqlite数据源连接参数

  # Sqlite数据库配置
  sqlitedatasource:
    driver-class-name: org.sqlite.JDBC
    url: jdbc:sqlite:C:\Users\Administrator\Desktop\xxx.db
    username:
    password:

Sqlite数据源配置

        bean.setMapperLocations(

        return bean.getObject();

    @Bean("sqliteSqlSessionTemplate")
