示例11: createCacheKey

import org.apache.ibatis.type.TypeHandlerRegistry; //导入方法依赖的package包/类
/**
  * MyBatis认为，对于两次查询，如果以下条件都完全一样，那么就认为它们是完全相同的两次查询：
1. 传入的 statementId 
2. 查询时要求的结果集中的结果范围 （结果的范围通过rowBounds.offset和rowBounds.limit表示）；
3. 这次查询所产生的最终要传递给JDBC java.sql.Preparedstatement的Sql语句字符串（boundSql.getSql() ）
4. 传递给java.sql.Statement要设置的参数值
现在分别解释上述四个条件：
1. 传入的statementId，对于MyBatis而言，你要使用它，必须需要一个statementId，它代表着你将执行什么样的Sql；
2. MyBatis自身提供的分页功能是通过RowBounds来实现的，它通过rowBounds.offset和rowBounds.limit来过滤查询出来的结果集，这种分页功能是基于查询结果的再过滤，而不是进行数据库的物理分页；
由于MyBatis底层还是依赖于JDBC实现的，那么，对于两次完全一模一样的查询，MyBatis要保证对于底层JDBC而言，也是完全一致的查询才行。而对于JDBC而言，两次查询，只要传入给JDBC的SQL语句完全一致，传入的参数也完全一致，就认为是两次查询是完全一致的。
上述的第3个条件正是要求保证传递给JDBC的SQL语句完全一致；第4条则是保证传递给JDBC的参数也完全一致；
即3、4两条MyBatis最本质的要求就是：
                 调用JDBC的时候，传入的SQL语句要完全相同，传递给JDBC的参数值也要完全相同。
   CacheKey由以下条件决定：
    statementId  + rowBounds  + 传递给JDBC的SQL  + 传递给JDBC的参数值 + EnvironmentId参数
