MoonPark project:
This project applied Abstract factory and singleton pattern for service
Spec: MoonPark-Sequence-Diagram.png

Bootstrap: MoonParkApplication.java
IDE: Intellij
Project: Maven - SprintBoot 1.5.2.RELEASE
JavDoc: ~JavaDoc/index.html
Just demo without database
-------------------------------------------------------------------------------------------------------------
UnitTest:
Auto generation test case file.
Generate MoonParkUnitTests.java by template file: src/test/java/com/example/template/test-case-template.txt
Testing base on json file, it can be test for restFull API (org.springframework.boot.test.web.client.TestRestTemplate).
for example:
{
"type": "m1", // parking zone
"input": { // input param
"cardId": "abc",
"start": "2017-03-29 05:20:31",
"end": "2017-03-29 15:20:31"
},
"expected": { // expected result
"cost": 600.0
},
"normal": true, // normal or abnormal test case
"description": "start time and end time" // test case info
}
How to Run UnitTest:
step1: determine your case and create file with format [name].json at src/test/java/com/example/Test-Data/
note: file name is method name
step2:
Execute main method in src/test/java/com/example/TestCaseJavaFileGenerator.java
it create file src/test/java/com/example/MoonParkUnitTests.java
note: if you create new json file, please do this step again.
step3:
go to src/test/java/com/example/MoonParkUnitTests.java and run UnitTest

Task 5:
Firstly we must improved MoonPark performance:
Increase heap size of JVM when deployed (note: not over total RAM/2, or 32Gb).
Deploy load balancing web system, use database cluster, apply caching cluster (recommended Redis) for reduced db query.
Protect against DoS, DDoS, brute force attack: config at webserver application.

Secondly control by code:
Add secret http-header (protected Clickjacking), username/password to hidden with stranger.
Limit traffic per user (request/sec): apply Observer pattern, HandlerInterceptor, or Filter of servlet.
