自动装配同一类的两个不同的bean

Question

I have a class which wraps a connection pool, the class gets its connection details from a spring configuration as shown below:

    <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 @Autowire annotation.

My question is, how can i duplicate this bean and give it different connection details and then @Autowire it in the service. meaning In addition to above I will have :

    <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:

@Autowired //bean of id jedisConnector
JedisConnector beanA;

@Autowired //bean of id jedisConnectorPOD
JedisConnector beanB;

Answer 1

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

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

Answer 2

You can combine @Autowired with @Qualifier , but in this case instead of @Autowired , I suggest using @Resource :

@Resource(name="jedisConnector")
JedisConnector beanA;

@Resource(name="jedisConnectorPOD")
JedisConnector beanB;

or even simpler:

@Resource
JedisConnector jedisConnector;

@Resource
JedisConnector jedisConnectorPOD;
