Sample of ehCache

ehCache Sample

This is a sample of ehCache, I used the following technologies:

• Spring Boot 2.3.2.RELEASE
• Spring JPA
• H2
• ehCache *jUnit5

How to run?

1. Compile the project with the following command:

   mvn clean install

2. The project is a Spring Boot Application, so you can run inside of your ide or from terminal with the following command:

   mvn spring-boot:run

3. When starting the application, it will create the task table defined in the entity class and also it will insert 5000 rows of dummy data.

• The first time, when invoking the /sample-ehcache/task/all endpoint, the application will take approximately 800ms.
• If you run again the /sample-ehcache/task/all endpoint, it will take little time because the data was cached.

Rest endpoints

• Request: Get all Tasks

  url    : http://localhost:8080/sample-ehcache/tasks/all
  method : GET
  

• Request: Add new Task

  url    : http://localhost:8080/sample-ehcache/tasks/save
  method : PUT
  header : application/json
  body   : {
              "taskName":"example",
              "status":"To do"
           }
  

• Request: Modify a Task

  url    : http://localhost:8080/sample-ehcache/tasks/update
  method : POST
  header : application/json
  body   : {
              "id":5001,
              "taskName":"example",
              "status":"In progress"
           }
  

• Request: Delete a Task

  url    : http://localhost:8080/sample-ehcache/tasks/{taskId}/delete
  method : DELETE
  

• Request: Delete the Cache

  url    : http://localhost:8080/sample-ehcache/tasks/clear-cache
  method : DELETE
  

Or you can import the collection file on "postman" client to test the endpoints, the file is in:

/resources/endpoints/collection.json

How to connect to H2 database?

1. Go to http://localhost:8080/sample-ehcache/h2-console/
2. Setting the following parameters:

Driver class : org.h2.Driver
JDBC URL     : jdbc:h2:mem:test
User Name    : sa
Password     :

3. Click on Test Connection button, this should return Test successful
4. Click on Connect button.
5. Now you can see the TASK table.
