That's all the code you need to write! However, to get it to compile, you need to update the POM file
to include the Java mail dependencies. Listing 9-57 shows the additions required to build the updated
project.
Listing 9-57.
Java Mail Dependency
…
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>

To wire all this up, start by configuring Spring to be able to send e-mails in the first place. Using
Spring's
org.springframework.mail.javamail.JavaMailSenderImpl
lets you configure where the SMTP
server is and the appropriate values for it. Listing 9-58 shows the configuration that goes in
launch-
context.xml
for this bean.
Listing 9-58.
Configuring
JavaMailSenderImpl
…
<bean id="javaMailSender"
class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com"/>
<property name="port" value="587"/>
<property name="username" value="someusername"/>
<property name="password" value="somepassword"/>
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.starttls.enable">true</prop>
</props>
</property>
</bean>

To be able to test the e-mail sending capabilities, you use Google's Gmail SMTP functionality as the
mail server. Listing 9-58 shows the configuration required. All you need to do is replace the username
and password with your Gmail username and password.

Next, you can move on to configuring the job to process the new customers. To configure the input
for the first step, you configure a resource to read from that is passed from the command line, and a
FlatFileItemReader
that reads in the
customerWithEmail.csv
file. The writer for step 1 consists of the
previously mentioned
JdbcBatchItemWriter
using the
dataSource
, a provided
preparedStatement
, and
the
CustomerItemPreparedStatementSetter
coded in Listing 9-54. Listing 9-59 shows how you wire that
up for the first step in the job.

Unlike most SMTP servers used by enterprises, the Gmail server you're using for this example ignores
the
from
attribute of the e-mail when it's sent and replaces it with the name of the account from which
you logged in.
