# 37.5 混合XA和non-XA的JMS连接

当使用JTA时，primary JMS `ConnectionFactory`bean将能识别XA，并参与到分布式事务中。有些情况下，你可能需要使用non-XA的`ConnectionFactory`去处理一些JMS消息。例如，你的JMS处理逻辑可能比XA超时时间长。

如果想使用一个non-XA的`ConnectionFactory`，你可以注入`nonXaJmsConnectionFactory` bean而不是`@Primary` `jmsConnectionFactory` bean。为了保持一致，`jmsConnectionFactory` bean将以别名`xaJmsConnectionFactor`来被使用。

示例如下：

```java
// Inject the primary (XA aware) ConnectionFactory
@Autowired
private ConnectionFactory defaultConnectionFactory;
// Inject the XA aware ConnectionFactory (uses the alias and injects the same as above)
@Autowired
@Qualifier("xaJmsConnectionFactory")
private ConnectionFactory xaConnectionFactory;
// Inject the non-XA aware ConnectionFactory
@Autowired
@Qualifier("nonXaJmsConnectionFactory")
private ConnectionFactory nonXaConnectionFactory;
```
