Spring Boot控制器在mongodb中防止在快速连续请求时多次插入

@Document
public class MyDocument {
    @Id
    private String id;
    private String data;
    @Version
    private Long version;
}

@RestController
@RequestMapping("/api")
public class MyController {

    @Autowired
    private MongoTemplate mongoTemplate;

    @PostMapping("/insert")
    public ResponseEntity<String> insertData(@RequestBody MyDocument doc) {
        Query query = new Query(Criteria.where("id").is(doc.getId()).and("version").is(doc.getVersion()));
        Update update = new Update().set("data", doc.getData()).inc("version", 1);
        UpdateResult result = mongoTemplate.updateFirst(query, update, MyDocument.class);
        
        if (result.getMatchedCount() == 0) {
            return ResponseEntity.status(HttpStatus.CONFLICT).body("Data has been modified by another request.");
        }
        return ResponseEntity.ok("Data inserted successfully.");
    }
}

@PostMapping("/insert")
public ResponseEntity<String> insertData(@RequestBody MyDocument doc) {
    Query query = new Query(Criteria.where("id").is(doc.getId()));
    Update update = new Update().set("data", doc.getData());
    MyDocument existingDoc = mongoTemplate.findAndModify(query, update, FindAndModifyOptions.options().returnNew(true), MyDocument.class);
    
    if (existingDoc == null) {
        return ResponseEntity.status(HttpStatus.CONFLICT).body("Data is being modified by another request.");
    }
    return ResponseEntity.ok("Data inserted successfully.");
}
