        map1.put("NAME", "朱元璋");  
        map2.put("NAME", "常遇春");

        list.add(map1);list.add(map2);list.add(map3);list.add(map4);list.add(map5);  

        System.out.println("***排序前***");  

        for(Map<String, Object> map:list){  
            System.out.println(map.get("NAME"));  
        }  

        System.out.println("***排序后***");  

        Collections.sort(list, new MapComparator());  

        for(Map<String, Object> map:list){  
            System.out.println(map.get("NAME"));  
        }  
    }  

}  

结果：

***排序前***  
朱元璋  
常遇春  
张无忌  
郭靖  
洪七公  
***排序后***  
常遇春  
郭靖  
洪七公  
张无忌  
朱元璋
