Spring batch using mysql SQLSyntaxErrorException 表batchJOB_INSTANCE不存在，属性spring.batch.jdbc.initialize-schema = ALWAYS
Spring batch using mysql SQLSyntaxErrorException table batchJOB_INSTANCE does not exist and property spring.batch.jdbc.initialize-schema = ALWAYS
问：
我正在使用 mysql 8.0 和 spring batch 4.3.5 和 spring boot 2.x。
我在运行批处理时遇到此异常。
异常为 java.sql.SQLSyntaxErrorException：表“dsm-batch.batchJOB_INSTANCE”不存在
这是完整堆栈跟踪。

我在 spring batch core jar 模式文件中搜索了 mysql，该文件中确实不存在此表。 这是我的配置。
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
任何帮助将不胜感激。

根据错误消息： ，表前缀是 ，但在属性中设置为不同的值。Table 'dsm-batch.batchJOB_INSTANCE' doesn't existdsm-batchspring.batch.jdbc.table-prefix=batch
您应相应地更新此属性：
spring.batch.jdbc.table-prefix=dsm-batch

我把spring.batch.jdbc.table-prefix=batch放在我的属性文件中。 当 spring batch 创建它的表时，它添加了batch_tablename例如，BATCH_JOB_EXECUTION_CONTEXT。 但是当它查询时，会搜索没有 _ 字符的 batchtable。例如，batchjob_execution_context。 删除spring.batch.jdbc.table-prefix=batch解决了我的问题。
