Spring boot 类型为'；org.springframework.boot.autoconfigure.batch.BatchProperties$Job'；那是找不到的

开发基于XML的Spring Boot JPA批处理方法。我开发了一些代码，它开始给我下面的错误

有人能告诉我这个错误吗

理想情况下，我希望应该创建JobLauncher和JobRepository实例以供应用程序使用。这里还需要配置什么

错误：

Description:

Field studentTestJob in com.its.example.service.HelloWorldService required a bean of type 'org.springframework.boot.autoconfigure.batch.BatchProperties$Job' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.boot.autoconfigure.batch.BatchProperties$Job' in your configuration.

尝试将

id=“StudentTestJob”

更改为小写

id=“StudentTestJob”

I second@Patrick，作业id应为

StudentTestJob

。标识符区分大小写。
