如何在多个线程之间共享事务

Question

我有一个已配置的nirayana独立JTA和两个REST端点

1. 开始交易

2. 使用交易

   @GetMapping("/starttx")  
   public String starttx() throws NotSupportedException, SystemException  
   {  
   //        TransactionManager transactionManager = com.arjuna.ats.jta.TransactionManager.transactionManager();  
       UserTransaction userTransaction = com.arjuna.ats.jta.UserTransaction.userTransaction();  
       System.out.println(userTransaction);  
       userTransaction.begin();  
       System.out.println(userTransaction.getStatus());  
       System.out.println("trx started");  
       return "started";  
   }  
   
   @GetMapping("/createAccount")  
   // @Transactional(rollbackFor=RuntimeException.class)  
   public String account() throws SystemException  
   {  
   
       UserTransaction userTransaction = com.arjuna.ats.jta.UserTransaction.userTransaction();  
       System.out.println(userTransaction.getStatus());  
   
       em.persist(new AccountEntity("acc1"));  
       return "created account";  
   } 
   

我分别调用starttrx和createAccount，但是在createAccount中，事务状态为6，这意味着它不处于活动状态，如何与createAccount共享在starttx端点中创建的事务？
