– Create a business model class
– Create Utilize class to encode/decode an Image to Base64 String
– For Restful Web Services, create Controllers: POST, GET
– For Rest-Template client, create Spring Rest-Template with functions: POST, GET
– Apply Rest-Template client
– Build & Enjoys with results

II. Practice

4. For Restful Web Services, create Controllers: POST, GET

5. For Rest-Template client, create Spring Rest-Template with functions: POST, GET

6. Apply Rest-Template client

7. Build & Enjoys with results

Create folders:
– For Client: “C:\\client” & “C:\\client\\get”
– For Server: C:\\server
Build & Run by Order:
1. Run Spring Restful Service
2. Run Spring RestTemplate Client
