aop的Spring JavaConfig：作用域代理

Question

這是什麼JavaConfig相當於？

<!-- an HTTP Session-scoped bean exposed as a proxy 
    that acts as session storage. 
--> 
<bean id="checkOutCounter" class="org.brightworks.genesis.client.forms.CheckOutCounter" scope="session"> 
    <!-- this next element effects the proxying of the surrounding bean --> 
    <aop:scoped-proxy/> 
</bean> 

嘗試宣告它這樣，但它只是作爲一個單身

@Bean 
public CheckOutCounter checkOutCounter(){ 
    return new CheckOutCounter(); 
} 

什麼是說的XML配置的相同呢？

Answer 1

對於組件初始化：

@Component 
@Scope(value = "session", proxyMode = ScopedProxyMode.INTERFACES) 

對於@Bean：

@Bean 
@Scope(value="session", proxyMode = ScopedProxyMode.TARGET_CLASS) 
public CheckOutCounter checkOutCounter(){ 
    return new CheckOutCounter(); 
}
