Question

以下代码段/代码在Eclipse中运行，但是当我构建可执行JAR并尝试运行它时，它显示以下错误，

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is java.lang.UnsupportedOperationException: No add column syntax supported by org.hibernate.dialect.SQLiteDialect

数据库配置-

public DataSource dataSource() {
        DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
        dataSourceBuilder.driverClassName("org.sqlite.JDBC");
        //dataSourceBuilder.url("jdbc:sqlite:/C:/Projects/project1/db/sampledata.db3"); // working fine, when running through eclipse
        dataSourceBuilder.url("jdbc:sqlite:sampledata.db3"); // working fine when running through eclipse

        return dataSourceBuilder.build();   
}

application.properties

spring.profiles.active=dev
#spring.jpa.properties.hibernate.dialect= com.example.demo.config.SQLiteDialect
spring.jpa.properties.hibernate.connection.url = org.sqlite.JDBC
spring.jpa.database-platform= com.example.demo.config.SQLiteDialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.EJB3NamingStrategy
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

可执行jar-在这种情况下需要提供什么数据库路径？

我已经推荐了其中的几个，试图使用：resource，但是没有用。因此，我们将不胜感激。

可执行JAR Bean创建-不起作用
