类型问题：我的数据库里的user_id字段是bigint型的，
我的映射文件写的没错，

<resultMap id="BaseResultMap" type="com.kenny.pojo.MallUser">
        <id column="user_id" jdbcType="BIGINT" property="userId"/>
        <result column="nick_name" jdbcType="VARCHAR" property="nickName"/>
        <result column="login_name" jdbcType="VARCHAR" property="loginName"/>
        <result column="password_md5" jdbcType="VARCHAR" property="passwordMd5"/>
        <result column="introduce_sign" jdbcType="VARCHAR" property="introduceSign"/>
        <result column="address" jdbcType="VARCHAR" property="address"/>
        <result column="is_deleted" jdbcType="TINYINT" property="isDeleted"/>
        <result column="locked_flag" jdbcType="TINYINT" property="lockedFlag"/>
        <result column="create_time" jdbcType="TIMESTAMP" property="createTime"/>
    </resultMap>
    <sql id="Base_Column_List">
        user_id,nick_name,login_name,password_md5,introduce_sign,address,is_deleted,
        locked_flag,create_time
    </sql>

错的是user的接口类。

@Mapper
@Repository
public interface MallUserMapper {

    MallUser selectByPrimaryId(int id);

}

把int改为long就行了
