篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了去哪网实习总结：递归构建“流程运行顺序”的XML文件（JavaWeb）相关的知识，希望对你有一定的参考价值。
本来是以做数据挖掘的目的进去哪网的，结构却成了系统开发。。。
只是还是比較认真的做了三个月，老师非常认同我的工作态度和成果。。
。
实习立即就要结束了，总结一下几点之前没有注意过的变成习惯和问题。分享给大家。
同一时候打个广告：去哪网内审部招JavaWeb开发实习生，时间很自由。每周一天、周六周日甚至都能够，时间充裕的小伙伴给我留言啊，挣个零花钱，还能长点经验。
。。。（保研的、想工作的大四狗最合适只是了。。。
）
map的结构为(thisProcessID, thisProcessType;nextProcessID1,nextProcessType1;...;nextProcessIDk,nextProcessTypek;)，假设processType部位start、end、split、join，则type和id同样。。。。
跑一下代码就知道是怎么回事了。直接上代码：

@SuppressWarnings({ "rawtypes", "unchecked" })
public void formXMLfile(Map nodeMap){
/*穿行没问题
nodeMap.put("1", "start;2,2");
nodeMap.put("2", "2;3,3");
nodeMap.put("3", "3;4,end");
nodeMap.put("4", "end");
*/
/* 简单并行没问题，但须要去重处理
nodeMap.put("1", "start;2,split");
nodeMap.put("2", "split;3,3;4,4");
nodeMap.put("3", "3;5,join");
nodeMap.put("4", "4;5,join");
nodeMap.put("5", "join;6,end");
