自动装配的相同类的两个不同的豆 [英] Autowiring two different beans of same class

问题描述

我有一个包裹连接池类，类会从Spring配置其连接的详细信息，如下图所示：

＆LT;豆的id =jedisConnector级=com.legolas.jedis.JedisConnector初始化方法=的init 灭法=消灭＆GT;
        ＆LT;属性名=主机值=$ {} jedis.host/＆GT;
        ＆LT;属性名=端口值=$ {} jedis.port/＆GT;
    ＆LT; /豆＆GT;


这个bean是在服务以后使用，并与自动装配的 @Autowire 注释。

我的问题是，我怎么能在服务复制这个bean，并给它不同的连接详细信息，然后 @Autowire 它。
这意味着除了上面我将有：

＆LT;豆的id =jedisConnectorPOD级=com.legolas.jedis.JedisConnector初始化方法=的init 灭法=消灭＆GT;
        ＆LT;属性名=主机值=$ {} jedis.pod.host/＆GT;
        ＆LT;属性名=端口值=$ {} jedis.pod.port/＆GT;
    ＆LT; /豆＆GT;


和在服务：

  @Autowired // ID jedisConnector豆
JedisConnector beanA;ID jedisConnectorPOD的@Autowired //豆
JedisConnector beanB;
 

解决方案

您可以将 @Autowired 与 @Qualifier ，但在这种情况下，而不是 @Autowired ，我建议使用 @Resource ：

  @资源（名称=jedisConnector）
JedisConnector beanA;@Resource（NAME =jedisConnectorPOD）
JedisConnector beanB;
 

或者更简单的：

  @Resource
JedisConnector jedisConnector;@Resource
JedisConnector jedisConnectorPOD;
 

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;

解决方案

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;
