我正在尝试创建数据库和表，然后需要在初始化 .JAR 时通过 Java 1.8v 将静态数据插入到表中。
这是我的 application.properties 文件:
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql:
spring.datasource.username =root
spring.datasource.password =root
server.port=9090
spring.jpa.hibernate.ddl-auto = create-drop
spring.jpa.show-sql = true
spring.jpa.hibernate.naming-strategy =
org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect =
org.hibernate.dialect.MySQL5Dialect
spring.datasource.initialization-mode=always
spring.datasource.platform=mysql
spring.datasource.schema=schema-mysql.sql
spring.datasource.data=data-mysql.sql
spring.datasource.initialize=true
spring.datasource.continue-on-error=true
在编译时出现此错误:

schema.sql 是:
create database if not exists 'data1' ;
data.sql 包含:
create table if not exists 'data1'.'table_1' (table_id INT(11) , name VARCHAR(255));
如何在Java应用程序启动时自动创建和插入数据，而不需要手动创建和插入。
最佳答案
错误表明它无法访问该文件: 导致:org.springframework.boot.context.properties.source.InvalidConfigurationPropertyValueException:值为“ServletContext资源[/schema-mysql.sql]”的属性spring.datasource.schema无效:指定的资源不存在。
默认行为是在应用程序上下文下搜索 data-.sql 和 schema-.sql，如您所见 in DataInitializer .
但是，您的问题可能非常简单，您需要在文件名之前添加“classpath:”，以表明您正在提供文件和位置。就像是 spring.datasource.data=classpath:/my-seed-data.sql
