Detailed Explanation
The Auth Controller manages various user-related operations, including updating user profiles and authorities. By extending existing APIs, you can efficiently incorporate new functionalities.
Key Components:
- User API: Handles operations like listing, updating, and viewing users.
- Profile API: Manages the profile of the authenticated user.
Implementing the Auth Controller
Let’s start by copying the existing put API and modifying it to create an updateAuth endpoint.
Sample Code: AuthController.java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
@RestController @RequestMapping("/users") public class AuthController { @Autowired private AccountService accountService; // Existing APIs... @PutMapping("/updateAuth") public ResponseEntity<AccountViewDTO> updateAuthority( @PathVariable Long userId, @Valid @RequestBody AuthoritiesDTO authoritiesDTO) { Account account = accountService.updateAuthorities(userId, authoritiesDTO.getAuthorities()); AccountViewDTO viewDTO = new AccountViewDTO(account); return ResponseEntity.ok(viewDTO); } // Other methods... } |
Comments:
- @PutMapping(“/updateAuth”): Maps HTTP PUT requests to the updateAuthority method.
- @PathVariable Long userId: Extracts the user ID from the URL.
- @Valid @RequestBody AuthoritiesDTO authoritiesDTO: Validates and binds the request body to AuthoritiesDTO.
Step-by-Step Code Explanation
- Endpoint Definition: The @PutMapping annotation defines the endpoint /updateAuth for updating user authorities.
- Path Variable: The method accepts userId as a path variable to identify which user’s authority is being updated.
- Request Body: The method takes AuthoritiesDTO as input, ensuring the data is valid before processing.
- Service Interaction: It calls accountService.updateAuthorities to perform the update operation.
- Response: Returns the updated account information as AccountViewDTO.
Output of the Update Authority API
Upon successful execution, the API returns a JSON response with the updated user details:
1 2 3 4 5 |
{ "id": 1, "username": "admin", "authorities": "ROLE_ADMIN" } |
Creating the AuthoritiesDTO
Data Transfer Objects (DTOs) play a crucial role in transferring data between layers. The AuthoritiesDTO captures the authority information from the client.
Sample Code: AuthoritiesDTO.java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
public class AuthoritiesDTO { @NotBlank(message = "Authorities cannot be blank") private String authorities; // Getters and Setters public String getAuthorities() { return authorities; } public void setAuthorities(String authorities) { this.authorities = authorities; } } |
Comments:
- @NotBlank: Ensures that the authorities field is not empty.
- Getters and Setters: Allow for accessing and modifying the authorities field.
Step-by-Step Code Explanation
- Field Definition: The authorities field captures the roles assigned to the user.
- Validation: The @NotBlank annotation ensures that the authorities are provided.
- Accessor Methods: Standard getter and setter methods enable data encapsulation.
Syntax Breakdown
- Private Variable: Encapsulates the authorities data.
- Validation Annotations: Enforce data integrity.
- Accessor Methods: Facilitate safe access and modification of the data.
Implementing the Update Authority API
With the Auth Controller and DTO in place, the next step is to implement the service layer that handles the business logic.
Sample Code: AccountService.java
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
@Service public class AccountService { @Autowired private AccountRepository accountRepository; public Account updateAuthorities(Long userId, String authorities) { Optional<Account> optionalAccount = accountRepository.findById(userId); if (!optionalAccount.isPresent()) { throw new UserNotFoundException("User ID " + userId + " not found"); } Account account = optionalAccount.get(); account.setAuthorities(authorities); return accountRepository.save(account); } // Other service methods... } |
Comments:
- @Service: Marks the class as a service layer component.
- updateAuthorities Method: Handles the logic for updating user authorities.
- Exception Handling: Throws an exception if the user is not found.
Step-by-Step Code Explanation
- Service Annotation: @Service indicates that this class contains business logic.
- Dependency Injection: AccountRepository is injected to interact with the database.
- Method Logic:
- Find User: Retrieves the user by userId.
- Update Authorities: Sets the new authorities if the user exists.
- Save Changes: Persists the updated user information to the database.
Adding Comments in the Program Code
Comments are crucial for code readability and maintenance. Here’s how to document the updateAuthorities method:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
/** * Updates the authorities of a specific user. * * @param userId the ID of the user to update * @param authorities the new authorities to assign * @return the updated Account object * @throws UserNotFoundException if the user is not found */ public Account updateAuthorities(Long userId, String authorities) { // Retrieve the user by ID Optional<Account> optionalAccount = accountRepository.findById(userId); // Throw exception if user does not exist if (!optionalAccount.isPresent()) { throw new UserNotFoundException("User ID " + userId + " not found"); } // Update the authorities Account account = optionalAccount.get(); account.setAuthorities(authorities); // Save and return the updated user return accountRepository.save(account); } |
Explaining the Code Step-by-Step
- Method Documentation: Describes the purpose, parameters, return type, and exceptions of the method.
- Retrieve User: Uses findById to fetch the user from the repository.
- Exception Handling: Checks if the user exists; if not, throws a UserNotFoundException.
- Update Authorities: Sets the new authorities for the user.
- Save Changes: Saves the updated user back to the repository and returns the result.
Example Output of the Update Authority API
When the API is executed successfully, the response will be similar to:
1 2 3 4 5 |
{ "id": 1, "username": "admin", "authorities": "ROLE_ADMIN" } |
If an invalid userId is provided, the API will respond with an error message:
1 2 3 4 5 6 7 |
{ "timestamp": "2023-10-10T10:00:00Z", "status": 404, "error": "Not Found", "message": "User ID 10 not found", "path": "/users/updateAuth/10" } |
Testing the Update Authority API
Testing ensures that your API behaves as expected under various scenarios. Here’s how to test the updateAuth endpoint.
Using Postman for API Testing
Step 1: Open Postman and create a new PUT request.
Step 2: Set the request URL to:
1 |
http://localhost:8080/users/updateAuth/1 |
Step 3: In the Headers section, add:
1 2 |
Content-Type: application/json Authorization: Bearer <your-admin-token> |
Step 4: In the Body section, select raw and enter:
1 2 3 |
{ "authorities": "ROLE_ADMIN" } |
Step 5: Click Send to execute the request.
Expected Responses
- Success (200 OK):
12345{"id": 1,"username": "admin","authorities": "ROLE_ADMIN"} - User Not Found (404 Not Found):
1234567{"timestamp": "2023-10-10T10:00:00Z","status": 404,"error": "Not Found","message": "User ID 10 not found","path": "/users/updateAuth/10"}
Handling Invalid User IDs
Attempting to update authorities for a non-existent user ID will result in an error. Ensure that your API gracefully handles such scenarios by returning meaningful error messages.
Example:
Request URL:
1 |
http://localhost:8080/users/updateAuth/10 |
Response:
1 2 3 4 5 6 7 |
{ "timestamp": "2023-10-10T10:00:00Z", "status": 404, "error": "Not Found", "message": "User ID 10 not found", "path": "/users/updateAuth/10" } |
Conclusion of Testing
Thorough testing validates that the updateAuth API functions correctly, handles errors gracefully, and maintains the security of user operations.
