spring自定义属性编辑器使用dome

Spring xml配置

<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">

<property name="propertyEditorRegistrars">

<list>

<ref bean="customCollectionEditorRegistrar"/>

</list>

</property>

</bean>

<bean id="customCollectionEditorRegistrar" class="com.focustech.channelfy.product.service.factoryBean.CustomCollectionEditorRegistrar">

<property name="factoryListEditor" ref="factoryListEditor"/>

</bean>

<bean id="factoryListEditor" class="org.springframework.beans.propertyeditors.CustomCollectionEditor">

<constructor-arg name="collectionType" value="com.focustech.channelfy.product.service.factoryBean.FactoryArrayList" type="java.lang.Class"/>

</bean>

CustomCollectionEditorRegistrar自定义注册机

public class CustomCollectionEditorRegistrar implements PropertyEditorRegistrar {

private PropertyEditor factoryListEditor;

public void setFactoryListEditor(PropertyEditor factoryListEditor) {

this.factoryListEditor = factoryListEditor;

}

@Override

public void registerCustomEditors(PropertyEditorRegistry registry) {

registry.registerCustomEditor(FactoryList.class, factoryListEditor);

}

}

FactoryArrayList需要自定属性

public class FactoryArrayList<T extends MatchingBean<K>,K> extends ArrayList<T> implements FactoryList<T,K> {

public T getBean(K k) throws NoFindClassException {

Iterator<T> iterator = this.iterator();

while (iterator.hasNext()){

T next = iterator.next();

if (next.getBean(k)){

return next;

}

}

throw new NoFindClassException();

}

}

自定属性实现接口

public interface FactoryList<E extends MatchingBean<K>,K> extends List<E> {

E getBean(K var1) throws NoFindClassException;

}

自定属性实现接口

public interface MatchingBean<T> {

boolean getBean(T t);

}
