Class TransactionController

java.lang.Object

com.loomcache.springboot.controller.TransactionController

@RestController
@Conditional(LoomServerEnabledCondition.class)
@RequestMapping("/api/transactions")
public class TransactionController
extends Object

REST controller for managing server-side transactions.

Endpoints

• POST /api/transactions — begin a transaction
• POST /api/transactions/{id}/operations — buffer an operation
• POST /api/transactions/{id}/commit — commit a transaction
• POST /api/transactions/{id}/rollback — rollback a transaction

The controller talks directly to the embedded CacheNode's TransactionManager — it does not go over TCP. For cross-node work use the TCP wire protocol via LoomClient#newTransaction() instead.
