• spring.batch.initialize-schema=always表示让spring batch在数据库里面创建默认的数据表。

• 各sql见:
• org/springframework/batch/spring-batch-core/4.1.2.RELEASE/spring-batch-core-4.1.2.RELEASE.jar!/org/springframework/batch/core/schema-mysql.sql

• spring.batch.schema=classpath:
• 不能用逗号分隔,空格也不行,都当做是一个文件名，找不到

spring.batch.table-prefix=motor_
Caused by: java.sql.SQLSyntaxErrorException: Table 'motor.motor_job_instance' doesn't exist
没用，表还是batch开头建的

要把batch的表删掉，执行时motor的表才会创建。
但如果加people则不用。
