Crud Microservices

Goal

Create a code sample with:

• Rest application (SpringBoot);
• Microservices architecture;
• Database Connection;
• Docker

Rules implementation

Password security scanner(http://passwordmeter.com); I will try create a simple resource, Passwords, that receive a character to analyze and persist.

Stack

• Java
• Maven
• Spring Cloud Netflix
• Spring Boot Admin
• Cassandra
  • Docker Maven Plugin
• Junit
• REST-assured
• Mockito
• Docker

Overview +

Run

With Docker

 cd ../microservices
 mvn clean install
 docker-compose up

With Vagrant

 cd ../microservices/vagrant
 vagrant up
 

After some minutes, you can visit the client directly at http://localhost:8080/edge/passwords The endpoint will show the passwords saved in Cassandra;

[]

You can create some register in Cassandra;

curl \
    -H "Content-Type: application/json" \
    -X POST \
    -d 'simplePassword' \
    http://localhost:8080/edge/passwords

This will be return:

{
    "passwordCharacters":"simplePassword",
    "score":48,
    "complexity":"Good"
}
