#788 sort util 封装数组或者集合固定的排序方法

com.feilong.core.util.SortUtil
新增 sortListByFixedOrderArray(List<T>, T...) 和 sortListByFixedOrderList(List<T>, List<T>) 方法

对集合 list 按照指定的固定顺序 fixedOrderItemList 进行排序.

说明:

默认使用的是 UnknownObjectBehavior.AFTER ,不在指定固定顺序的元素将排在后面

示例:

assertThat(
                 sortListByFixedOrderList(toList("张飞", "关羽", "刘备"), toList("刘备", "张飞", "关羽")), //
                 contains("刘备", "张飞", "关羽"));

重构:

对于以下代码:

try{
    Collections.sort(
        list,
        new FixedOrderComparator<>(
            StoPropertyConstants.PRPT_ITEM_HYPELAUNCH,
            StoPropertyConstants.PRPT_ITEM_MIADIDAS_VALUE_EN,
            StoPropertyConstants.PRPT_ITEM_PRESONALLZATION_CODE,
            StoPropertyConstants.PRPT_ITEM_PERSALES_CODE,
            StoPropertyConstants.PRPT_ITEM_VIP_CODE,
            StoPropertyConstants.PRPT_ITEM_COMINGSOON_CODE,
            StoPropertyConstants.PRPT_ITEM_DISCOUNT_CODE,
            StoPropertyConstants.PRPT_ITEM_NORMAL_CODE,
            StoPropertyConstants.PRPT_ITEM_NOSALE));
 }catch (Exception e){
     LOGGER.error("itemType sort error:{},itemType:{}", e, JsonUtil.format(itemType));
 }

可以重构成:

com.feilong.core.util.SortUtil.sortListByFixedOrderList(
    list,
    toList(
            StoPropertyConstants.PRPT_ITEM_HYPELAUNCH,
            StoPropertyConstants.PRPT_ITEM_MIADIDAS_VALUE_EN,
            StoPropertyConstants.PRPT_ITEM_PRESONALLZATION_CODE,
            StoPropertyConstants.PRPT_ITEM_PERSALES_CODE,
            StoPropertyConstants.PRPT_ITEM_VIP_CODE,
            StoPropertyConstants.PRPT_ITEM_COMINGSOON_CODE,
            StoPropertyConstants.PRPT_ITEM_DISCOUNT_CODE,
            StoPropertyConstants.PRPT_ITEM_NORMAL_CODE,
            StoPropertyConstants.PRPT_ITEM_NOSALE));

#789 新建 ComparatorUtil
#791 新建 ContainsStringPredicate

使用场景,参考

<bean class="com.feilong.context.converter.IfStringToBeanConverter">

        <property name="predicate">
            <bean class="com.feilong.core.util.predicate.ContainsStringPredicate" p:searchCharSequence="TRADE_NOT_EXIST" />
        </property>

        <property name="trueStringToBeanConverter">
            <bean class="com.feilong.netpay.alipay.query.AlipayTradeNotExistStringToBeanConverter" />
        </property>

        <property name="falseStringToBeanConverter">
            <bean class="com.feilong.context.converter.XMLMapBuilderStringToBeanConverter">
                <property name="beanClass" value="com.feilong.netpay.alipay.query.AlipaySingleQueryResultCommand" />

                <property name="nameAndValueMapBuilder">
                    <bean class="com.feilong.context.converter.builder.XmlNodeNameAndValueMapBuilder" p:xpathExpression="/alipay/response/trade/*" />
                </property>

                <property name="beanBuilder">
                    <bean class="com.feilong.context.converter.builder.AliasBeanBuilder" />
                </property>
            </bean>
        </property>
    </bean>
