JobRepositoryFactoryBean错误spring批处理

Question

我开始学习spring batch，遇到一个问题，当我想使用JobRepositoryFactoryBean在数据库中持久化作业的状态时。编译器显示：

“原因：org.springframework.beans.factory.beanCreationException：创建类路径资源[springconfig.xml]中定义的名为'job repository'的bean时出错：调用init方法失败；嵌套异常为html" target="_blank">java.lang.noClassDefoundError：org/springframework/jdbc/core/simple/parameterizedRowMapper”

但使用MapJobRepositoryFactoryBean时不会出错

我用的是spring 5

但当我使用：

Answer 1

您正在使用SpringBatchV2.2和SpringFramework5。这将无法正常工作，因为parameterizedrowmapper在Spring Framework4.2+中被删除了（因此出现了例外）。

我建议您使用SpringBatchV4.1（因为不再维护V2.x)，您的问题应该得到解决。

管理Spring依赖关系的最好方法是让Spring Boot为您完成这件事，可以从start.Spring.io生成一个项目，也可以使用Spring Boot BOM。通过这两种方法，您将拥有正确的Spring项目依赖项，这些依赖项已知可以很好地协同工作。
