mapUnderscoreToCamelCase

是否开启驼峰命名： 如果开启驼峰命名，若数据库中表的字段为last_name,java类中属性的名为lastName,那么mybatis会自动将查询结果映射到lastName中

mybatis-config.xml

<settings> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings>

Employee

public class Employee { private int id; private String lastName; private String email; private String gender; ... }
