How do you do this? For this example, you'll use a single step job that reads in the input file and
writes it to the output file; you don't need an ItemProcessor. Because the only code you need to write is
that for the
Customer
class, you can start there; see Listing 9-4.
Listing 9-4.
Customer.java
package com.apress.springbatch.chapter9;
import java.io.Serializable;
public class Customer implements Serializable {
private static final long serialVersionUID = 1L;
private long id;
private String firstName;
private String middleInitial;
private String lastName;
private String address;
private String city;
private String state;
private String zip;
// Accessors go here
...
}
As you can see in Listing 9-4, the fields of the
Customer
object map to the fields in the
customer.csv
file.
1
With the item coded, you can begin configuring the job.
2
The input side should be familiar from
Chapter 7. Listing 9-5 shows the configuration of the input file as a resource (the value is passed in via a
job
parameter), the
FlatFileItemReader
configuration, and the required reference to the
Customer
object.
1
The
Customer
object has an
id
attribute that you use later; it has no data in the file.
2
As with all the previous examples in this topic,
batch.properties
for the project is the same as it was
using MySQL in Chapter 2. Also, unless otherwise specified,
launch-context.xml
is the same as well.
