1. 批量插入把根据字段插入和普通插入两个方法进行分开，使代码风格和Mybatis官方保持一致； 

2. 批量插入老版本代码迁入com.itfsw.mybatis.generator.plugins.BatchInsertOldPlugin不影响老版本生成的代码使用；

### 6. 批量插入插件
提供了一个批量插入batchInsert方法，因为方法使用了使用了JDBC的getGenereatedKeys方法返回插入主键，所以只能在MYSQL和SQLServer下使用。
建议配合数据Model属性对应Column获取插件（ModelColumnPlugin）插件使用，会把批量插入方法从batchInsert(@Param("list") List<Tb> list)增强为batchInsert(@Param("list") List<Tb> list, @Param("insertColumns") Tb.Column ... insertColumns)，实现类似于insertSelective插入列！
提供了批量插入batchInsert和batchInsertSelective方法，因为方法使用了使用了JDBC的getGenereatedKeys方法返回插入主键，所以只能在MYSQL和SQLServer下使用。
需配合数据Model属性对应Column获取插件（ModelColumnPlugin）插件使用，实现类似于insertSelective插入列！
PS:为了和Mybatis官方代码风格保持一致，1.0.5+版本把批量插入方法分开了，基于老版本1.0.5-版本生成的代码请继续使用“com.itfsw.mybatis.generator.plugins.BatchInsertOldPlugin”不影响使用
PS:继续PS，本来想继续保留老版本代码，不影响老版本已经生成代码使用的，但是始终没有绕过BindingException，只能把代码移入BatchInsertOldPlugin类~~~~~

### 8. 数据Model属性对应Column获取插件
项目中我们有时需要获取数据Model对应数据库字段的名称，一般直接根据数据Model的属性就可以猜出数据库对应column的名字，可是有的时候当column使用了columnOverride或者columnRenamingRule时就需要去看数据库设计了，所以提供了这个插件获取model对应的数据库Column。
* 配合Example Criteria 增强插件（ExampleEnhancedPlugin）使用，这个插件还提供了asc()和desc()方法配合Example的orderBy方法效果更佳。
* 配合批量插入插件（BatchInsertPlugin）使用，批量插入会被增强成batchInsert(@Param("list") List<XXX> list, @Param("insertColumns") XXX.Column ... insertColumns)。
* 配合批量插入插件（BatchInsertPlugin）使用，batchInsertSelective(@Param("list") List<XXX> list, @Param("selective") XXX.Column ... insertColumns)。
