map 轉爲 list 鍵值對數組，Map.entrySet().toArray()

將Map 轉爲 List<Map.entey>，便於前端json處理。

即，從

{"id2":"ddd","id1":"lxf"}

到

[{"id2":"ddd"},{"id1":"lxf"}]

---

Map.entrySet().toArray()

@RequestMapping("/testListMap")
    public Object testListMap(){
        Map m = new HashMap();
        m.put("id1","lxf");
        m.put("id2","ddd");
        return m.entrySet().toArray();
    }
