将初始数据导入Spring Boot应用程序

Question

According to the documentation http://docs.spring.io/spring-boot/docs/current/reference/html/howto-database-initialization.html to import data on startup you can define these 2 properties inside application.properties:

spring.datasource.data=data.sql
spring.datasource.schema=schema.sql

This works when you have both of these files, but i don't have schema. I am generating db schema using hibernate

spring.jpa.hibernate.ddl-auto=create-drop

Previous workaround Importing Data with spring boot was to define file for schema.sql blank, but it doesn't work anymore. I will get exception that file can't be blank or null .

In spring application i simply defined

<jdbc:initialize-database data-source="simpleDataSource">
    <jdbc:script location="classpath:dbscripts/data.sql"/>
</jdbc:initialize-database>

and it worked.

Is there a way to have same behaviour also in springBoot?

Answer 1

只需删除schema.sql + config选项，Spring Boot应该会自动选择sata.sql 。

Answer 2

According to spring source code - data.sql will be invoked only if schema.sql file exist and it is not empty. So if you only need scripts from data.sql add some simple query to schema.sql like

SELECT 1;

Also in application.properties add

spring.datasource.initialization-mode=always

because default value is used only for embedded data sources.
