Review

In the previous section, we have implemented the Java classes. In this section, we will start writing the configuration files to complete our Spring application.

Part 1: Introduction and Functional Specs
Part 2: SendGrid account setup
Part 3: Java classes
Part 4: XML configuration
Part 5: Running the Application

Configuration

To complete our application, here are the important configuration files that needs to be declared:

spring.properties
applicationContext.xml
spring-servlet.xml
web.xml

The spring.properties file contains the SendGrid user and key values to access the Web API. This is equivalent to your SendGrid's username and password.

	# SendGrid properties
	sendgrid.api.user=YOUR-USER-API
	sendgrid.api.key=YOUR-KEY-API
