JobRepositoryFactoryBean春季批处理错误

Question

我开始学习spring-batch，当我想使用CCD_ 1将作业的状态持久化到数据库中。编译器显示：

">由以下原因引起：org.springframework.beans.factory.BeanCreationException：创建类路径资源[springConfig.xml]中定义的名称为"jobRepository"的bean时出错：调用init方法失败；嵌套异常为java.lang.NoClassDefFoundError:org/springframework/jdbc/core/ssimple/ParameterizedRowMapper">

但当我使用MapJobRepositoryFactoryBean时没有错误

我用的是弹簧5

Answer 1

您正在将Spring Batch v2.2与Spring Framework 5一起使用。这将无法正常工作，因为在SpringFramework4.2+中已经删除了ParameterizedRowMapper(因此出现了异常(。

我建议您使用SpringBatch v4.1(因为v2.x不再维护(，您的问题应该得到修复。

管理Spring依赖关系的最好方法是让Spring Boot为您完成这项工作，方法是从start.Spring.io生成项目，或者使用Spring Boot BOM。通过这两种方式，您将获得正确的Spring项目依赖项，这些依赖项可以很好地协同工作。
