Autowiring two different beans of same class
提问by Noam Nevo
I have a class which wraps a connection pool, the class gets its connection details from a spring configuration as shown below:
我有一个包装连接池的类，该类从 spring 配置中获取其连接详细信息，如下所示：
<bean id="jedisConnector" class="com.legolas.jedis.JedisConnector" init-method="init" destroy-method="destroy">
<property name="host" value="${jedis.host}" />
<property name="port" value="${jedis.port}" />
</bean>
This bean is later used in a service and is autowired with the @Autowireannotation.
这个 bean 稍后在服务中使用，并与@Autowire注解自动装配。
My question is, how can i duplicate this bean and give it different connection details and then @Autowireit in the service.
meaning In addition to above I will have :
我的问题是，如何复制此 bean 并为其提供不同的连接详细信息，然后再将@Autowire其添加到服务中。意思是除了上述我将有：
<bean id="jedisConnectorPOD" class="com.legolas.jedis.JedisConnector" init-method="init" destroy-method="destroy">
<property name="host" value="${jedis.pod.host}" />
<property name="port" value="${jedis.pod.port}" />
</bean>
and in the service:
并在服务中：
@Autowired //bean of id jedisConnector
JedisConnector beanA;
@Autowired //bean of id jedisConnectorPOD
JedisConnector beanB;

You can combine @Autowiredwith @Qualifier, but in this case instead of @Autowired, I suggest using @Resource:
您可以@Autowired与结合使用@Qualifier，但在这种情况下@Autowired，我建议使用@Resource：
@Resource(name="jedisConnector")
JedisConnector beanA;
@Resource(name="jedisConnectorPOD")
JedisConnector beanB;
or even simpler:
甚至更简单：
@Resource
JedisConnector jedisConnector;
@Resource
JedisConnector jedisConnectorPOD;

@Autowired
@Qualifier("jedisConnector")
JedisConnector beanA;
@Autowired
@Qualifier("jedisConnectorPOD")
JedisConnector beanB;
