你检查一下你的mybatis-config.xml文件对不对，我的是

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!--配置全局属性-->
    <settings>
        <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值-->
        <setting name="useGeneratedKeys" value="true"/>

        <!-- 使用标签替换列别名 默认：true-->
        <setting name="useColumnLabel" value="true"/>

        <!--开始驼峰命名转换：Table{create_time} ->Entity{createTime} -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>

</configuration>
