Spring 批量禁用元表的自动创建

Question

我正在使用 Spring Batch，我知道它可以自动创建元表。我不需要它们，我试过了： spring.batch.initializer.enabled= false 或 spring.batch.initialize-schema: never 我总是有这个错误：

Caused by: org.postgresql.util.PSQLException: ERROR: relation "batch_job_instance" does not exist

I am using Spring Batch and I am aware it can do an automatic creation of the meta tables. I don't need them.

Spring Batch 不会自动创建表，Spring Boot 会根据您的指示自动创建表。

[To turn them off] I tried : spring.batch.initializer.enabled= false or spring.batch.initialize-schema: never and I always have this error

您的属性都不正确。属性的名字是 spring.batch.jdbc.initialize-schema。请检查 reference documentation.
