java map获取值方式

1.建立一个迭代器

2.while循环将值取出

3.使用get获取值

 

/**
* 删除
* @param reqmap
* @return
*/
@RequestMapping(value = "/delete",method = RequestMethod.POST)
public Map<String, Object> delete(@RequestBody Map<String, Object> reqmap){
System.out.println("收到数据"+reqmap);

Map<String, Object> map = new HashMap<String,Object>();

Iterator<String> iterator = reqmap.keySet().iterator();

while(iterator.hasNext()){
Object key = iterator.next();
System.out.println(reqmap.get(key));
}

map.put("msg", "删除成功");

return map;

}
