The simplest implementation of winter framework source code SSH

I have been writing this framework the other day and now I am releasing the source code!

Main functions:

1. Automatically encapsulate the form into an object (similar to struts2)

2. automatically generate addition, deletion, modification, and query SQL statements based on the object (similar to hibernate)

3. Support spring dynamic injection. You can hand over custom actions to spring for management.

4. Custom tab Library

5. Support for pseudo-static functions

Pseudo-static implementation. You can use a regular expression !~

This framework is almost the most streamlined implementation of SSH.

The configuration is flexible and simple. It is much easier than the three frameworks, and there is only one package, which is very small!

Packages and classes:

Org. Pan. Code this is the package of the core class

Main classes:

Filter-forwarding controller-Action Manager-field type converter-spring support-JDBC support-SQL Creation

The main configuration file is request. xml.

If you are interested, contact me and complete it together !~

Some source code is attached:
