Lab 5 - Spring Security

You can continue to your last lab assignment to add security with JWT to your project.

Requirements

  • There are two roles admin and user.
    • admin can access all endpoints.
    • user can access only /products endpoint.
  • Use UserDetailsService to load the user from the database.
  • Create UaaController to implement signin and signup endpoints.
  • Make necessary changes to set user_id in product with the current request holder's user id when saveProducts is invoked.
    • You can access the current request holder via SecurityContextHolder.
  • Generated token should be valid for 15 minutes.
  • Use AOP to filter out any offensive words.
    • You can use any kind of offensive words dictionary or you can even create one for testing.
    • Assuming spring is an offensive word and if the input is : springing, it should be filtered out as ******ing.
      • Create WaaOffensiveWords aspect.
    • If the same user sends more than 5 different requests that contain offensive words in last 30 minutes, do not accept the requests of this user for next 15 minutes and return the error message Max Bad Words Requests Limit has been Reached. You need wait for X minutes. Change X with remaining time of the ban.
      • This implementation should be stateless. You cannot hold any data in the server's memory. You can design table/tables to implement this feature.
      • To practice further (optional), you can use redis instead of using PostgreSQL.
      • Create WaaRequestFilter aspect.
  • Continue to your UI project and implement signin and signup functionality.
  • Make necessary changes in your UI project to communicate with backend server.
    • Send the token in each request except for signin and signup functions.
    • You can store the token in thelocalStorage.

Technical Details

  • Use n-tier software architecture model.
  • Use DTOs.
  • PostgreSQL is recommended as a Relational Database system.
  • Populate your database with dummy data using data.sql.

Submission

  • Fork this repository and push your changes.
  • Once you finished your project, send a Pull Request. (Send only one Pull Request once you finish the assignment.)

Important Notes

  • You are not allowed to share codes with your classmates. If detected, you will get NC.
  • For pairs:
    • Individual's work will be checked from the commits.
    • Share tasks evenly and fairly.
    • To have a clearer understanding of pair programming:

      • Pair programming is an agile software development technique in which two programmers work together at one workstation. One, the driver, writes code while the other, the observer or navigator reviews each line of code as it is typed in. The two programmers switch roles frequently.

      • Wikipedia

  • Remember to respect the code honor submission policy. All written code must be original. Presenting something as one’s own work when it came from another source is plagiarism and is forbidden.

  • Plagiarism is a very serious thing in all American academic institutions and is guarded against vigilantly by every professor.
