Nothing in Listing 9-74 should be unfamiliar. You're using the same input file you used in the
previous examples in this chapter. The configuration consists of the file reference (
Resource
), the
configuration of the
FlatFileItemReader
using
DelimitedLineTokenizer
and
BeanWrapperFieldSetMapper
to read the file, and a reference to the
Customer
bean to create them as required.
On the output side, you need to create three ItemWriters: the XML writer and its dependencies, the
JDBC writer and its dependencies, and the
CompositeItemWriter
that wraps both of the other writers.
Listing 9-75 shows the configuration for the output of this step as well as the configuration for the step
and job.
