el表达式解析Map嵌套取值

List<Map<String, Object>> combinelist = new ArrayList<Map<String, Object>>();
Map<String, Object> newmap;
for(Map<String, Object> map:plantdlist){
	newmap = new HashMap<String,Object>();
	newmap.put("scdtime", map.get("scdtime").toString());
	newmap.put("inflow", map.get("inflow").toString());
	for(String tdmc:planthlist){
		newmap.put(tdmc, combine(tdmc,map.get("scdtime").toString(),planinfolist));
		break;
	}
	combinelist.add(newmap);
}

private Map<String, Object> combine(String tdmc,String scdtime,List<Map<String, Object>> planinfolist){
Map<String, Object> nmap = new HashMap<String,Object>();
for(Map<String, Object> tdmap:planinfolist){
	if(tdmc.equals(tdmap.get("famc").toString()) && scdtime.equals(tdmap.get("scdtime").toString())){
		System.out.println(tdmap.get("scdtime").toString()+"--"+tdmap.get("famc").toString());
