我正在开发 Spring Boot + Batch 非常基本的示例。引导的版本为2.1.1.RELEASE。在此示例中，我使用了schema-mysql.sql，并期望自动创建Batch元数据示例，但是会出错。
任何快速指针吗？使用MYSQL版本8.0.X
错误：

spring.datasource.password=root
spring.batch.initialize-schema=ALWAYS
spring.datasource.schema=schema-mysql.sql
答案 0 :(得分：2)
DDL脚本位于org.springframework.batch.core包中，因此您需要在属性文件中指定数据源架构，如下所示：
spring.datasource.schema=org/springframework/batch/core/schema-mysql.sql
答案 1 :(得分：2)
它的旧线程但是其他人可以从中受益，这里有完整的包类路径，并且必须定义initialize schema always。
需要定义以下属性：
spring.datasource.schema=classpath:/org/springframework/batch/core/schema-mysql.sql
spring.batch.initialize-schema=always
或在yml文件中
spring:
datasource:
schema:
- classpath:/org/springframework/batch/core/schema-mysql.sql
jpa:
hibernate:
ddl-auto: create
batch:
initialize-schema: always
或者如果将schema-mysql.sql复制到资源文件夹中，则使用spring.datasource.schema=classpath:schema-mysql.sql
答案 2 :(得分：1)
我开始无所适从地遇到这个属性的问题。 我意识到我将其设置为仅用于测试（但未使用）。 因此，我决定删除财产，然后一切又开始正常工作...
答案 3 :(得分：0)
您可以使用
structure(list(Group.1 = c("alpha", "beta", "gamma"), x100 =
c(1.31729175522923,
0.985278656706214, 0.156200287397951), x110 = c(1.54471416538581,

例如我使用 mariaDb 和 springBootVersion = 2.3.4.RELEASE。设置：
schema: 'classpath:sql/schema/schema1.sql,classpath:sql/schema/schema2.sql'
