我可以在bean id属性中使用Spring EL吗



我可以在bean的id属性中使用SpEL吗?

例如:<bean id="#{T(com.om.m).PublicStaticFinalStringProperty}"...

这样就不起作用了,我应该改变什么,或者这是不可能的?

奇怪但可能(示例使用弹簧3.1)。不同版本工作:

<?xml version="1.0" encoding="UTF-8"?>

    <bean id="testBean" class="Bean">
        <property name="value" value="weird"/>
    </bean>
    <bean id="${x.y.z}" class="Bean">
        <property name="value" value="but"/>
    </bean>
    <bean id="#{testBean.value}" class="Bean">
        <property name="value" value="${x.y.z}"/>
    </bean>
</beans>

Bean.java

public class Bean implements InitializingBean {
    String value;
    public void setValue(String value) {
        this.value = value;
    }
    public void afterPropertiesSet() throws Exception {
        System.out.println(value);
    }
}
