/**
 *
 * 背景
 * 现在的数据层的开发，大多会使用如MyBatis或JPA之类的开发工具。这些开发工具给我们的开发过程中带来了极大的便利。
 * 但是在一些极端的场景下往往原生的jdbc方式操作数据库更灵活，性能更高。由于部分场景下MyBatis或JPA之类无法满足我的需求，所以我打算自己封装一套查数据库的工具类。
 *
 * 我们会用到fastjson,druid,mysql所以pom.xml增加依赖如下：
 *
 * <dependency>
 *     <groupId>com.alibaba</groupId>
 *     <artifactId>fastjson</artifactId>
 *     <version>1.2.62</version>
 * </dependency>
 * <dependency>
 *     <groupId>com.alibaba</groupId>
 *     <artifactId>druid</artifactId>
 *     <version>1.1.9</version>
 * </dependency>
 * <!-- Mysql驱动包 -->
 * <dependency>
 *     <groupId>mysql</groupId>
 *     <artifactId>mysql-connector-java</artifactId>
 * </dependency>
 *
