/api/users/123

@RestController
@RequestMapping("/api")
public class ApiController {
    
    @GetMapping("/test")
    public String getNoParam() {
        return "无参GET请求API接口方法";
    }
}

@GetMapping("/user/{id}")
public String getWithPathParam(@PathVariable String id) {
    return "RESTful请求传值方法，ID: " + id;
}

@GetMapping("/user")
public String getWithQueryParam(@RequestParam String id) {
    return "GET普通请求传值方法，ID: " + id;
}

@PostMapping("/save")
public String postMethod(@RequestBody Map<String, Object> map) {
    return "POST请求接收成功: " + map;
}

@PutMapping("/update/{id}")
public String putMethod(@PathVariable String id, @RequestBody Map<String, Object> map) {
    return "PUT请求接收成功，ID: " + id + ", 数据: " + map;
}

@DeleteMapping("/delete/{id}")
public String deleteMethod(@PathVariable String id) {
    return "DELETE请求接收成功，ID: " + id;
}
