Inside spring framework from source code (1)

The spring could be most popular java framework in this world. It had been born at 2002 which is even earlier than Adobe Flex (dead already). Spring source code provided a very elegant way about how to organize your code and define the Apis.  As java developer, all of us should spend time to read source code Spring and get deeply know how to write the solid and high quality code.

I am trying to summarize what I got when I review the code and provide a quick guide to understand the code easily. Hope I can finish this giant project.

First of all, if we fork the source code from https://github.com/spring-projects/spring-framework it is simple to figoure the modules dep from gradle file.
For easy purpose, I draw the diagram to represent the dependencies.  The black line is for compile dep and yellow one is for optional dep (just ignore it at very first begging to keep everything simple).

Add caption
Let's go start from spring-core and spring-beans on the next chapter since it is so popular star used by almost other modules.

The python 2.7 didn't update the path accordingly. Based on the assumption above, the following solution worked for me. To install Visual Studio 2008 Express Edition with all required components: 1.

How to convert the ResultSet to Stream

Java 8 provided the Stream family and easy operation of it. The way of pipeline usage made the code clear and smart. However, ResultSet is still go with very legacy way to process. Per actual ResultSet usage, it is really helpful if converted as Stream. Here is the simple usage of above: StreamUtils.uncheckedConsumer is required to convert the the SQLException to runtimeException to make the Lamda clear.

How to run odoo(openerp8) in IDE from source on windows

(requirements.txt contains all dependencies. ) The pip will install the python module automatically. However, the real world always bring us the issues because our C++ compile environment is not setup correctly.  we will get the link error when pip try to install psycopg2 (driver to access postgresql db.). Go to  http://www.stickpeople.com/projects/python/win-psycopg/  and choose the compiled binary file directly. For Python-ldap, go to  http://www.lfd.uci.edu/~gohlke/pythonlibs/ 5. Finally, go to http://sourceforge.net/projects/pywin32/files/pywin32 and choose correct version for python-win32service. 6. If you are family with eclipse a lot,
