我尝试在我的本地机器上复制这个问题,并找到了解决方案。
您需要通过扩展org.hibernate.dialect来创建自己的方言

registerFunction("concat", new VarArgsSQLFunction(StringType.INSTANCE, "", "||", ""));
registerFunction("mod", new SQLFunctionTemplate(StringType.INSTANCE, "?1 % ?2"));

还需更新spring.jpa.database-platform=com.mehul.SQLiteDemo.dialect.SQLDialect
到您的包名和类名。
注:我使用了<hibernate.version>5.6.3.Final</hibernate.version>
org.hibernate.dialect.Dialect
配置了 SQLDialect。 - I AM GROOT
