目前,我們正在使用Spring框架,並使用下面的XML: -ConversionNotSupportedException使用RuntimeBeanRefrence時對象的列表
<bean id="A" class="com.foo.baar.A" >
<property name="attributes">
<set value-type="com.foo.bar.B">
<ref bean="X" />
<ref bean="Y" />
</set>
</property>
</bean>
<bean id="X" class="com.foo.bar.X" />
<bean id="Y" class="com.foo.bar.Y" />
,其中X類和Y類擴展B類
類A有二傳手作爲如下: -
public void setAttributes(List<B> attributes) {
this.attributes = attributes;
}
現在,我要消除上述XML,我編程設定豆如下: -
List<Object> beanRefrences = new ArrayList<Object>();
for(String attribute : attributes) {
Object beanReference = new RuntimeBeanReference(attribute);
beanRefrences.add(beanReference);
}
mutablePropertyValues.add(propertyName, beanRefrences);
有了上面的代碼,我收到以下錯誤: -
nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.util.ArrayList' to required type 'java.util.List' for property 'attributes';
nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.springframework.beans.factory.config.RuntimeBeanReference] to required type [com.foo.bar.B] for property 'attributes[0]': no matching editors or conversion strategy found
誰能給我如何使它正常工作的指針?
好像您設置了'RuntimeBeanReference'的實例,您應該在其中設置'B'的實例。 – zeroflagL
@DexterMorgan,你做到了嗎? – whiskeysierra
