Question

我开始学习春季批处理，但遇到一个问题，当我想使用JobRepositoryFactoryBean将作业的状态保存在数据库中。编译器显示：

“ 原因：org.springframework.beans.factory.BeanCreationException：创建在类路径资源[springConfig.xml]中定义的名称为'jobRepository'的bean时出错：初始化方法的调用失败；嵌套异常为java。 lang.NoClassDefFoundError：org / springframework / jdbc / core / simple / ParameterizedRowMapper “

但当我使用MapJobRepositoryFactoryBean

时不会出错

我正在使用Spring 5

但使用时不会出错：

Answer 1

您正在将Spring Batch v2.2与Spring Framework 5一起使用。由于ParameterizedRowMapper在Spring Framework 4.2+中已被删除，因此无法正常工作（因此除外）。

我建议您使用Spring Batch v4.1（因为不再维护v2.x），并且您的问题已得到解决。

管理Spring依赖项的最好方法是让Spring Boot通过start.spring.io或使用Spring Boot BOM生成项目来为您完成。通过这两种方式，您将拥有正确的Spring项目依赖关系，这些依赖关系可以很好地协同工作。
