Spring Batch

In this post, we will show you how to use Spring Batch to read an XML file with your ItemReader using StaxEventItemReader and write its data to Oracle Database using Custom ItemWriter. We will also learn how to use ItemProcessor to process input data before writing to the database.

Custom ItemReader or ItemWriter is a class where we write our own way of reading or writing data. In Custom Reader we are required to handle the chunking logic as well. This comes in handy if our reading logic is complex and cannot be handled using Default ItemReader provided by spring.
