/**
 * 默认的 {@link PartitionRunnableBuilder}.
 * 
 * 重构:
 * 
 * 
 * 
 * 对于以下代码:
 * 
 * 
 *  * 
 * ThreadUtil.execute(list, 5, new PartitionRunnableBuilder{@code }(){
 * 
 *     public Runnable build(final List{@code } perBatchList,PartitionThreadEntity partitionThreadEntity,Map{@code } paramsMap){
 * 
 *         return new Runnable(){
 * 
 *             public void run(){
 *                 map.putAll(handle(perBatchList, noList));
 *             }
 *         };
 *     }
 * });
 * 
 * 
 * 
 * 可以重构成:
 * 
 *  * ThreadUtil.execute(list, 5, new DefaultPartitionRunnableBuilder{@code <>}(new Call{@code }(){
 * 
 *     public void call(List{@code } perBatchList,PartitionThreadEntity partitionThreadEntity,Map{@code } paramsMap){
 *         map.putAll(handle(perBatchList, noList));
 *     }
 * }));
 * 
 * 
 * 从 13 行 简写到 6 行
 * 
 * 
 * 
 * 如果是JDK8+,还可以使用lambda重构成:
 * 
 * 
 *  * ThreadUtil.execute(list, 5, new DefaultPartitionRunnableBuilder{@code <>}(new Call{@code }(){
 * 
 *     public void call(List{@code } perBatchList,PartitionThreadEntity partitionThreadEntity,Map{@code } paramsMap){
 *         map.putAll(handle(perBatchList, noList));
 *     }
 * }));
 * 
 * 
 * 从 13 行 简写到 6 行
 *
