I searched in the spring batch core jar schema file for mysql and this table really does not exist in that file. This is my configs.

spring.datasource.url=jdbc:mysql://localhost:3306/dsm-batch?useUnicode=yes
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.platform=mysql
spring.batch.schema=classpath:/org/springframework/batch/core/schema-mysql.sql
spring.batch.jdbc.table-prefix=batch
spring.batch.jdbc.initialize-schema = ALWAYS

any help would be appreciated.

CodePudding user response：

According to the error message: Table 'dsm-batch.batchJOB_INSTANCE' doesn't exist, the table prefix is dsm-batch, but it is set to a different value in the property spring.batch.jdbc.table-prefix=batch.

You should update this property accordingly:

spring.batch.jdbc.table-prefix=dsm-batch

CodePudding user response：

I put spring.batch.jdbc.table-prefix=batch in my properties file. When spring batch creates it's tables, it added batch_tablename E.G, BATCH_JOB_EXECUTION_CONTEXT. but when it queries, searches for batchtable without _ character. E.G, batchjob_execution_context. removing spring.batch.jdbc.table-prefix=batch solved my problem.
