SSH deep Adventure (ix) struts2+dwz+uploadify implementation of multiple files (files and pictures, etc.) upload

In the Gxpt_uas system, to implement files (files and pictures, etc., can be flexibly configured) batch upload to MongoDB, in the process of learning, learning MongoDB, and realize the function of batch upload, realize the idea: On the basis of DWZ reference to the official examples with the existing GXPT to achieve, during the period read a lot of blogs, for these frameworks, the main study or should be based on document guidance, more look at the official manual (even if the document is very small), more information, overall, can be said that this is the DWZ integration of the plug-in, is mainly JS to achieve, gradually realized the JS, we are the front-end framework of the study is a truth (Easyui, DWZ, ExtJS, etc.), as long as we have a learning mentality, all seemingly new content, we can be as old content learning, knowledge of different architectures, Learning the idea is not changed, the introduction is very fast, the framework does encapsulate a lot of content, gradually in-depth study it, cut to the point:

Summarize

This effect, is still good, a lot of content it is encapsulated into the framework, for multi-file upload, each file will invoke the back-end action method, this is the perfect combination of its and Struts2, careful + document = implementation, this part of the content still need our many practical, For the framework to use more learning to learn more, more harvest.

Contact (ssh+web) framework for about 1.5 months, the overall can realize that the framework to solve a problem, provides a good solution, simplifying the developers write code granularity, we have to stop, gradually thinking about the principle of the framework? Wait, that's what we really need to improve. First, of course, is a very important first step in getting started.
