Where to go Web Internship Summary: Recursive construction of the "Process execution order" XML file (Javaweb)

Originally to do the purpose of data mining in which network, the structure has become a system development ...

But still more serious to do for three months, the teacher is very agree with my work attitude and results ...

The internship is coming to an end, summarizing a few things that have not been noticed before to become habits and problems, to share to everyone.

At the same time to play an advertisement: to which network Internal audit department recruit Javaweb Development intern, Time is very free, a week, Saturday Sunday even can, the time of the small partners to give me a message ah, earn a pocket money, but also a long experience .... (GPA, want to work a senior dog is the most suitable ... ）

The structure of map is (Thisprocessid, thisprocesstype;nextprocessid1,nextprocesstype1; Nextprocessidk,nextprocesstypek;), if the Processtype part start, end, split, join, then the type and ID are the same ....

Run the code to know what's going on, directly on the code:
