• Basic Auth (Profile: basic-auth)
• OAuth2 (Profile: oauth2)
• SSL (Profile: ssl-auth)

Simple (No) Auth

1. Set profile

   SPRING_PROFILES_ACTIVE=simple-auth
   

2. Run the app

3. Call any endpoint

   # create a message
   curl -X POST \
     http://localhost:8080/api/messages \
     -d message-goes-here
     
   # get all messages
   curl http://localhost:8080/api/messages

Basic Auth

1. Set profile

   SPRING_PROFILES_ACTIVE=basic-auth
   

2. Run the app

3. Call endpoints with Basic Auth Header

   # create a message
   curl -X POST \
     http://localhost:8080/api/messages \
     -H 'Authorization: Basic YWRtaW46cGFzc3dvcmQ=' \
     -d message-goes-here
   
   # get all messages
   curl \
     http://localhost:8080/api/messages \
     -H 'Authorization: Basic YWRtaW46cGFzc3dvcmQ='

OAuth2

1. Set profile

   SPRING_PROFILES_ACTIVE=oauth2
   

2. Run the app

3. Create Token

   curl -X POST \
     http://localhost:8080/oauth/token \
     -H 'Content-Type: application/x-www-form-urlencoded' \
     -H 'Authorization: Basic a2MtY2xpZW50OmtjLXNlY3JldA==' \
     -d 'grant_type=client_credentials&scope=any'

4. Use Token (substitute {token} with value from previous step)

   # create a message
   curl -X POST \
     http://localhost:8080/api/messages \
     -H 'Authorization: Bearer {token}'
     -d message-goes-here
     
   # get all messages
   curl \
       http://localhost:8080/api/messages \
       -H 'Authorization: Bearer {token}'
   

SSL

1. Set profile

   SPRING_PROFILES_ACTIVE=ssl-auth
   

2. Use cert in root of project to call endpoints

Notes:

• port 8443 is used instead of 8080
• Keystore was generated with this command:

   keytool -genkeypair -alias tomcat -keyalg RSA -keysize 2048 
  -keystore keystore.jks -validity 3650
