and the mail configuration from application.properties
* add some real credentials if you want the app to send emails
* to activate Hipchat notifications proceed same as for email
## 2. Spring Boot App Client
* mvn clean install
* mvn spring-boot:run
* starts on port 8081
* basic auth client/client
### Relevant Articles:

# Greeter App
This app takes in the user's name and messages for different times of day as configuration parameters and outptus the greeting messge. For example it will take the name **John** and the message for morning time as **Good Morning** and output the message **Hello John, Good Morning**.
## Usage
Create and populate the class `GreetingConfig`, instantiate a `Greeter` using the `GreetingConfig` and use it get greeting messages:
```java
GreetingConfig greetingConfig = new GreetingConfig();
greetingConfig.put(USER_NAME, "World");
greetingConfig.put(MORNING_MESSAGE, "Good Morning");
greetingConfig.put(AFTERNOON_MESSAGE, "Good Afternoon");
greetingConfig.put(EVENING_MESSAGE, "Good Evening");
greetingConfig.put(NIGHT_MESSAGE, "Good Night");
Greeter greeter = new Greeter(greetingConfig);
greeter.greet();
```
