-     | aggressiveLazyLoading       true,     当设置为‘true’的时候，懒加载的对象可能被任何懒属性全部加载。否则，每个属性都按需加载。
-     | multipleResultSetsEnabled   true,     允许和不允许单条语句返回多个数据集（取决于驱动需求）
-     | useColumnLabel              true,     使用列标签代替列名称。不同的驱动器有不同的作法。参考一下驱动器文档，或者用这两个不同的选项进行测试一下。
-     | useGeneratedKeys            false,    允许JDBC 生成主键。需要驱动器支持。如果设为了true，这个设置将强制使用被生成的主键，有一些驱动器不兼容不过仍然可以执行。
-     | autoMappingBehavior         PARTIAL,  指定MyBatis 是否并且如何来自动映射数据表字段与对象的属性。PARTIAL将只自动映射简单的，没有嵌套的结果。FULL 将自动映射所有复杂的结果。
-     | defaultExecutorType         SIMPLE,   配置和设定执行器，SIMPLE 执行器执行其它语句。REUSE 执行器可能重复使用prepared statements 语句，BATCH执行器可以重复执行语句和批量更新。
-     | defaultStatementTimeout     null,     设置一个时限，以决定让驱动器等待数据库回应的多长时间为超时
