Add SQL provider class that help detecting a template file automatically

[kazuki43zoo]

for example:

package com.example.demo.mapper;

interface DemoMapper {
  @InsertProvider(type = TemplateFilePathProvider.class)
  void insert(Demo demo);
}

By default, you can load a template file (e.g. com/example/demo/mapper/DemoMapper/DemoMapper-insert.sql) automatically.

project-root
  + src
    + main
       + resources (just under class-path )
          + com
             + example
                + demo
                   + mapper
                      + DemoMapper 
                         - DemoMapper-insert.sql

This feature depends on mybatis/mybatis-3#1391 and mybatis/mybatis-3#1503. In other words, this feature required to use on MyBatis 3.5.1+.

Also you can customize path format using static setter methods of TemplateFilePathProvider.

• Can excludes mapper name in template file (e.g. com/example/demo/mapper/DemoMapper/insert.sql)

project-root
  + src
    + main
       + resources (just under class-path )
          + com
             + example
                + demo
                   + mapper
                      + DemoMapper 
                         - insert.sql

• Can exclude directory per mapper (e.g. com/example/demo/mapper/DemoMapper-insert.sql)

project-root
  + src
    + main
       + resources (just under class-path )
          + com
             + example
                + demo
                   + mapper
                      - DemoMapper-insert.sql

• Can excludes a package path (e.g. DemoMapper/DemoMapper-insert.sql)

project-root
  + src
    + main
       + resources (just under class-path )
           + DemoMapper 
               - DemoMapper-insert.sql

• Can adding a path prefix (e.g. sqls/)

project-root
  + src
    + main
       + resources (just under class-path )
          + sqls
             + com
                + example
                   + demo
                      + mapper
                         + DemoMapper 
                             - DemoMapper-insert.sql
