【中文标题】值为“类路径资源 [schema-mysql.sql]”的属性 spring.datasource.schema 无效：指定的资源不存在【英文标题】：Property spring.datasource.schema with value 'class path resource [schema-mysql.sql]' is invalid: The specified resource does not exist 【发布时间】：2019-05-09 10:01:10 【问题描述】：我正在开发 Spring Boot + Batch 非常基本的示例。 Boot 版本为2.1.1.RELEASE。在此示例中，我使用了 schema-mysql.sql 并希望自动创建批处理元数据示例，但它给出了错误。
任何快速的指针？使用MYSQL版本8.0.X
错误：

【问题讨论】：
你能发布你的类路径资源吗？ 我的回答有帮助吗？我看到您在这里使用了正确的属性：***.com/questions/53682367/…。如果是，请接受答案。 不，它不像我想的那样工作.. 【参考方案1】：它的旧线程但其他人可以从中受益，这里完整的包类路径和initialize schema always 必须定义..
需要定义这些属性：
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schema-mysql.sql被复制到资源文件夹中，那么使用spring.datasource.schema=classpath:schema-mysql.sql
【讨论】：
我添加了这个属性：spring.datasource.schema=classpath:custom_schema.sql 并在资源文件夹中添加了“custom_schema.sql”，但错误仍然存在......我错过了什么吗？【参考方案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
【讨论】：
【参考方案3】：我突然开始遇到这个属性的问题。 我意识到我只是为了测试而设置它（但它没有被使用）。 所以我决定删除该属性，然后一切又开始工作了......
【讨论】：
【参考方案4】：你可以使用
schema: 'classpath:sql/schema/schema1.sql,classpath:sql/schema/schema2.sql'
例如我使用 mariaDb 和 springBootVersion = 2.3.4.RELEASE。设置：
spring:
datasource:
driver-class-name: 'org.mariadb.jdbc.Driver'
url: 'jdbc:mariadb://localhost:3307'
name: schema_name
username: 'sa'
password: ''
initialization-mode: always
schema: 'classpath:sql/schema/schema1.sql,classpath:sql/schema/schema2.sql'
data: 'classpath:sql/my/data1.sql,classpath:sql/my/data2.sql'
jpa:
database-platform: org.hibernate.dialect.MySQL8Dialect
database: MYSQL
properties:
hibernate:
generate_statistics: "false"
use_sql_comments: "false"
format_sql: "false"
show_sql: "true"
hbm2ddl.auto: "none"
jdbc.batch_size: 1000
order_inserts: true
