Configuration

Configure the extension in VS Code settings:

{
  // Base URL for your Spring Boot application
  "springEndpoints.baseUrl": "http://localhost:8080",
  
  // Automatically scan for endpoints on startup
  "springEndpoints.scanOnStartup": true
}

🎓 Supported Annotations

The extension detects the following Spring annotations:

Class-level:

• @RestController

• @RequestMapping

Method-level:

• @GetMapping
• @PostMapping
• @PutMapping
• @DeleteMapping

    @GetMapping("/{id}")
    public User getUser(@PathVariable Long id) {
        // ...
    }
    
    @PostMapping
    public User createUser(@RequestBody UserDTO dto) {
        // ...
    }
    
    @DeleteMapping("/{id}")
    public void deleteUser(@PathVariable Long id) {
