MyBatis怎么进行双重foreach循环

这篇文章主要介绍MyBatis怎么进行双重foreach循环，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

进行双重foreach循环

mapname是一个Map> 对象

            #{key1},        #{key2},        #{value2}    

使用场景

比如说一个付款人下面对应的运单的金额，那么key1就是付款人编号，key2是运单编号，value2是分摊的金额

mybatis foreach循环,传入多个参数

上代码

controller：

@RequestMapping(value = "/findPage", method = RequestMethod.POST)    @ResponseBody    public Object findPage(@RequestParam(required=false) String jobCategory,@RequestParam(required=false) String ids,@RequestParam(required=false) String cities) {        try {            List listJob = new ArrayList();            List listIds = new ArrayList();            List listCities = new ArrayList();            //按照城市名称和工种查询            if(StringUtils.isNotBlank(jobCategory) && StringUtils.isNotBlank(cities)){                String[] temp = jobCategory.split(",");                String[] cityTemp = cities.split(",");                for(int i=0;i list = jobService.findPage(listJob, listIds, listCities);                return new ExtGridReturn(list.size(), list);            }            //按照工种查询            if(StringUtils.isNotBlank(jobCategory)){                String[] temp = jobCategory.split(",");                for(int i=0;i list = jobService.findPage(listJob, listIds, listCities);            return new ExtGridReturn(list.size(), list);        } catch (Exception e) {            LOGGER.error("分页获取信息出错", e);            return new ExceptionReturn(e);        }    }

mapper

/**     * 描述：根据工种查询列表     * @param jobCategorys     * @return     */    List findPage(@Param("jobCategorys") List jobCategorys,@Param("ids") List ids,@Param("workPlace") List workPlace);

xml

              select n.ID id,              n.NAME name,              n.WORKPLACE workPlace,              n.JOBCATEGORY jobCategory,              n.SALARY salary,              n.RESPONSIBILITIES responsibilities,              n.REQUIREMENTS requirements,              n.ISHOT isHot,              n.UPDATEDATE updateDate,              n.UPDATEUSER updateUser,              u.real_name updateName         from websites_job n         left join base_users u on n.updateUser = u.account                                       or    n.jobCategory in                                       #{item}                                                        or n.id in                                       #{item}                                                          or n.WORKPLACE in                                       #{item}                                               order by n.ISHOT,n.ID desc
