我怎么能意识到这一点:
@Autowired
private ArticoliOrdine articoliOrdine;
@Autowired
private Ordine ordine;
//I want to do this in my applicationContext
ArticlesOrderPK pk=new ArticolesOrderPK(order.getId(),article.getId());
两个getId()方法返回一个Integer
在我的applicationContext中,我尝试这样做:
<bean class="bean.ArticlesOrder" id="ArticlesOrder">
<property name="ArticlesOrderPK">
<bean class="bean.ArticolesOrderPK" id="ArticolesOrderPK">
<property name="idOrder" ref=""/>
<property name="idArticle" ref="" />
</bean>
</property>
</bean>
<bean class="bean.Ordine" id="order" scope="prototype"/>
如何将ArticleOrderPK.idOrder与Order.id和ArticolesOrderPK.idArticle绑定到Article.id? 谢谢,抱歉我的英文

你需要使用 SpEL - Spring Expression Language
,它带有 Spring 3.x +
在bean定义的value属性中(您需要与其他bean的属性绑定)使用下面的表达式
#{beanId.beanProperty} or #{beanId.someMethod()}
在你的情况下,它应该是下面的
<bean class="bean.ArticolesOrderPK" id="ArticolesOrderPK">
<property name="idOrder" value="#{order.getId()}"/>
<property name="idArticle" value="#{article.getId()}" />
</bean>
