1.添加属性statementType="STATEMENT"

2.且sql中的变量用${params},而不是#{params}，如果是字符串类型的数据要手动加上引号

        SELECT `id`,`name`,`email`,`mobile`         FROM `${tableName}`                                    and `id` = ${id}                                        and `name` = '${name}'                                        and `email` = '${email}'                                        and `mobile` = '${mobile}'
