如何使用spring-batch和MultiResourceItemReader读取文件夹中的所有文件? [英] How to read all files in a folder with spring-batch and MultiResourceItemReader?

问题描述

我想配置spring-batch以便顺序读取特定文件夹中的所有csv文件.

I want to configure spring-batch to read all csv files inside a specific folder sequentially.

以下内容不起作用，因为该委托将尝试打开一个名为*.csv的文件，该文件当然是无效的.我必须在这里更改什么?

The following does not work because the delegate will try to open a file named *.csv, which of course is invalid. What do I have to change here?

    @Bean
    public ItemReader<String> reader() {
        MultiResourceItemReader<String> reader = new MultiResourceItemReader<>();
        reader.setResources(new Resource[] {new FileSystemResource("/myfolder/*.csv")});
        reader.setDelegate(new FlatFileItemReader<>(..));
        return reader;
}

等效的xml配置将编写如下，如何将其重写为仅Java的配置?

The equivalent xml configuration would be written as follows, how could I rewrite it to java only config?

<bean id="reader" class="org.springframework.batch.item.file.MultiResourceItemReader">
        <property name="resources" value="/mypfolder/*.csv"/>
        <property name="delegate" ref="flatFileItemReader"/>
</bean>
