没有DataSource的Spring启动+弹簧批处理 [英] Spring boot + spring batch without DataSource

问题描述

我正在尝试在spring boot项目中配置spring批处理，我想在没有数据源的情况下使用它。我发现 ResourcelessTransactionManager 是要走的路，但我不能让它工作。问题是我已经定义了另外3个dataSources，但是我不想在springBatch中使用它们。

I'm trying to configure spring batch inside spring boot project and I want to use it without data source. I've found that ResourcelessTransactionManager is the way to go but I cannot make it work. Problem is I already have 3 another dataSources defined, but I don't want to use any of them in springBatch.

我检查了默认实现 DefaultBatchConfigurer 如果它无法找到dataSource，它将完全按照我的意愿行事。问题是我有3个并且不想使用任何。

I've checked default implementation DefaultBatchConfigurer and if it is not able to find dataSource it will do exactly what I want. Problem is I've 3 of them and dont want to use any.

请不要建议在内存DB中使用hsql或其他因为我不想要它。

Please dont suggest to use hsql or other in memory DB as I dont want that.

推荐答案

我通过扩展DefaultBatchConfigurer类来解决这个问题，以便它忽略任何DataSource，因此它将配置一个基于地图的JobRepository 。

I got around this problem by extending the DefaultBatchConfigurer class so that it ignores any DataSource, as a consequence it will configure a map-based JobRepository.

示例：

@Configuration
@EnableBatchProcessing
public class BatchConfig extends DefaultBatchConfigurer {   

    @Override
    public void setDataSource(DataSource dataSource) {
        //This BatchConfigurer ignores any DataSource
    }
}
