How to read all files in a folder with spring-batch and MultiResourceItemReader?

Question

I want to configure

spring-batch

to read all

csv

files inside a specific folder sequentially.

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;

}

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>

I think you should use a PathMatchingResourcePatternResolver.
