oracle 使用 mybatis的时候，主键自动生成： 

<insert id="createBigOrder" parameterType="BigOrder" useGeneratedKeys="true" keyProperty="id">

        <selectKey resultType="int" order="BEFORE" keyProperty="id"> 

            SELECT SEQ_BIG_ORDER_ID.NEXTVAL FROM dual 

        </selectKey>  

    insert into 

    BIG_ORDER

    ( ID,

    BIGORDER_CODE,

MEMBER_ID,

SHOPGUIDE_ID,

CHANNEL_ID,

PAY_PRICE,

PAY_WAY,

GOODS_TOTAL_COUNT,

GSC_PICMIAN_ID,

PIC_URL,

PROVINCE,

CITY,

DETAIL_ADDRESS,

CONSIGNEE,

CONTACT_TEL,

BIND_SKU,

BIND_COUNT,

BIND_REASON,

BRAND_CODE,

REAL_SELL_PRICE,

CREATE_TIME,

UPDATE_TIME,

AREA,

SALE_SHOP,

ORIGINAL_TOTAL_PRICE,

CRM_ID,

rule_Id,

promotion_type_name,

P_TYPE_CODE,

P_PRICE_RULE,

P_MARKUP_PRICE,

P_QUANTITY_RULE,

P_START_TIME,

P_END_TIME,

    #{payPrice},

使用mybatis分页配置：

<configuration>

    <typeAliases>

        <typeAlias type="com.zyhao.demo.rest.entities.Demo" alias="Demo"/>

        <typeAlias type="org.zywx.lzsz.entity.order.BigOrder" alias="BigOrder"/>

        <typeAlias type="org.zywx.lzsz.entity.cart.ShoppingCart" alias="ShoppingCart" />

    </typeAliases>

    <!-- 添加mybatis分页插件 :指定oracle方言-->

    <plugins>

        <plugin interceptor="com.github.miemiedev.mybatis.paginator.OffsetLimitInterceptor">

            <property name="dialectClass" value="http://www.mamicode.com/com.github.miemiedev.mybatis.paginator.dialect.OracleDialect"/>

        </plugin>

    </plugins>

    <mappers>

        <mapper resource="mappers/demo.xml" />

        <mapper resource="mappers/order/bigorder.xml" />

        <mapper resource="mappers/cart/shoppingCart.xml"/>

    </mappers>

</configuration>
