模糊查询：

@Select({ "SELECT * FROM account where account like CONCAT('%',#{query},'%') or email like CONCAT('%',#{query},'%')"})Account findAccountByAccountOrMail(@Param("query") String query);

批量添加：

@Insert({ "<script>" + "INSERT INTO company_label(company_id,label_id) values " + " <foreach collection=\"item\" item=\"item\" index=\"index\" separator=\",\" > " + " (#{companyId},#{item}) " + " </foreach>" + "</script>"})void insertLabelForCompany(@Param("companyId") Long companyId,@Param("item") List<Long> item);

批量删除：

@Delete({ "<script>delete from company_label where company_id = #{companyId} and label_id in " + "<foreach collection = \"item\" item = \"item\" open=\"(\" separator=\",\" close=\")\">" + "#{item}" + "</foreach>" + "</script>"})void removeLabelForCompany(@Param("companyId") Long companyId,@Param("item") List<Long> item);

批量修改：

@Update(value = "<script>" + "update banner b set b.display = #{status} where b.id in "+ "<foreach item = 'item' index = 'index' collection = 'ids' open = '(' separator = ',' close = ')'>#{item}</foreach>" + "" + "</script>")int updateStatus(@Param("status") Long status, @Param("ids") Long[] ids);

批量查询：

@Select({ "<script>" + "select * from product where id in" + "<foreach item = 'item' index = 'index' collection = 'idList' open = '(' separator = ',' close = ')'>#{item}</foreach>" + "</script>"})List<Product> findByIdList(@Param("idList")List<Long> idList);

条件查询，if里面不仅可以判空，还可以判断是否满足某个条件

@Select({ "<script>SELECT * FROM company where 1=1 and parent_id = #{companyId} " + //平级 "<if test = \"isScanSameLevelValue == 1\">and type = #{type}</if>" + "<if test = \"isScanSameLevelValue == 0\">and type != #{type}</if>" + "</script> " }) List<Company> findCompanyConditional(@Param("isScanSameLevelValue") String isScanSameLevelValue, @Param("isScanParentLevelValue") String isScanParentLevelValue, @Param("companyId") Long companyId, @Param("type") Integer type);

条件查询：

*/@Lang(XMLLanguageDriver.class)@Select({"<script>select DISTINCT p.* FROM `us_product`.`hot_category_surgery` hcs "+ "LEFT JOIN `us_product`.`product` p ON hcs.`product_id` =p.`id`"+ "LEFT JOIN `us_product`.`category_surgery` cs on cs.`product_id` =p.`id`"+ "LEFT JOIN `us_product`.`merchant_product` mp on mp.`product_id` = p.`id`"+ "LEFT JOIN `us_product`.`org_product` op on op.`product_id` =p.`id`"+ "where p.`type` =1 and p.`is_for_sale` =1 "+ " <if test=\"hId != null\"> and hcs.hot_category_id = #{hId} and p.id = hcs.product_id</if>" + //热门类目id " <if test=\"categoryId != null\"> and cs.category_id = #{categoryId} and p.id = cs.product_id</if>" + //类目id " <if test=\"input != null\"> and (p.name like CONCAT('%',#{input},'%') or p.company like CONCAT('%',#{input},'%')) </if> "+ //用户输入,包括商品名和店铺名,模糊 " <if test = \" location != null\"> and p.location like CONCAT('%',#{location},'%') </if> "+ //位置..
