Trading Orders for Securities

This Spring application is a maven project. It exposes a REST API that talks to an in memory H2 database to perform some asynchronous order summary analysis of trade orders. An order consists of the following attributes:

• Order Id
• Side (BUY or SELL)
• Security
• Fund
• Quantity
• Price

What you will need

• Intellij IDE not necessary, but is highly recommended for Spring applications.

Building and running the application

• Intellij has support for maven dependencies. You should use spring-boot-maven-plugin.
• Use a shell and go to the project root directory (where the pom.xml file is) and type:

$ mvn clean package

This should build your .jar file in the target folder. Make sure port 8080 is not already in use — it’s the default port chosen by Tomcat. Change directories into the target folder. You should see the jar file in here. Build it by running:

$ java -jar <fileName>.jar
