注意：与MySQL不同！

方式一 

insert all into table(...) values(...) into table(...) values(...) select * from dual;

<insert id="addList" parameterType="java.util.List" useGeneratedKeys="false">INSERT ALL<foreach item="item" index="index" collection="list">INTO T_APPLAUD(ID,USER_ID,BUSINESS_TYPE,PRODUCT_ID,CREATE_TIME) VALUES(#{item.id, jdbcType=NUMERIC},#{item.userId, jdbcType=VARCHAR},#{item.businessType, jdbcType=VARCHAR},#{item.productId, jdbcType=VARCHAR},#{item.createdTime, jdbcType=NUMERIC})</foreach>SELECT 1 FROM DUAL</insert>

举例：

INSERT ALL
  INTO tableName (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
  INTO tableName (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
  INTO tableName (column1, column2, column_n) VALUES (expr1, expr2, expr_n)
SELECT count(*) FROM dual;
【注】：查询语句“SELECT count(*) FROM dual;”不能少，需要一条查询语句，查询结果不重要。

方式二 

insert into table(...) (select ... from dual) union all (select ... from dual)

<insert id="addList" parameterType="java.util.List" useGeneratedKeys="false">INSERT INTO T_APPLAUD(ID,USER_ID,BUSINESS_TYPE,PRODUCT_ID,CREATE_TIME)<foreach item="item" index="index" collection="list" separator="union all">(SELECT#{item.id},#{item.userId},#{item.businessType},#{item.productId},#{item.createdTime}FROM DUAL)</foreach></insert>
