Introducing Spring Framework

Chapter 13 ■ Adding E-mail and Scheduling Tasks
Listing 13-2 shows your XML configuration. As you can see, you are using the property placeholder
to read the email.properties file. Also, you are creating a mailSender bean that references the
org.springframework.mail.javamail.JavaMailSenderImpl class. This class is the Spring’s e-mail helper class
and it has several setters like host, port, username, password, and a javaMailProperties. You are setting these
property values by putting in placeholders. Listing 13-3 shows the e-mail properties file.
Listing 13-3. email.properties
email.host=smtp.gmail.com
email.port=587
email.username=username
email.password=password
■ ■Note If you are using a different e-mail provider such as Hotmail or Yahoo, you can check out their help pages to find
servers, ports, and more advance settings so you can configure the properties file and the javaMailProperties setters
accordingly.
Now let’s see Listing 13-4, the unit test. You are going to add some time measurement to see how long it will take
to send an e-mail. Why? This is because the JavaMailSenderImpl has a synchronous call for sending a message to the
server, meaning it must wait until the server accepts and responds that the e-mail was successfully sent.
Listing 13-4. MyDocumentsTest.java
