MyBatis如何进行双重foreach循环

MyBatis如何进行双重foreach循环

目录进行双重foreach循环使用场景mybatis foreach循环,传入多个参数上代码

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

listJob.add(Integer.valueOf(temp[i]));

}

for(int i=0;i

listCities.add(cityTemp[i]);

}

List 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

listJob.add(Integer.valueOf(temp[i]));
