json转map方法
Map<String,CityPo> map = new HashMap<String,CityPo>();
CityPo po = new CityPo();
po.setBuildCfgID(123);
po.setCurHp(456);
Hero hero = new Hero();
hero.setStrAge("11");
hero.setStrName("strName");
po.setHero(hero);
map.put( "name",po);
JSONObject json = JSONObject.fromObject( map ); //将map转成json
Map tmp = (Map)JSONObject.toBean(json, Map.class); //将json转回map
但是转回的map是Map<String,Object>的，有没有办法转成Map<String, CityPo>

ps: Map tmp = (Map)JSONObject.toBean(json, Map.class); 其中的Map.class为什么不让设Map<String,CityPo>.class?

[解决办法]

Java code

CityPo po = new CityPo();    po.setBuildCfgID(123);    po.setCurHp(456);    Hero hero = new Hero();    hero.setStrAge("11");    hero.setStrName("strName");    po.setHero(hero);    map.put("name", po);    JSONObject json = JSONObject.fromObject(po); // 将map转成json    CityPo poo = (CityPo) JSONObject.toBean(json, CityPo.class);    System.out.println(poo);

我这边有个JAR包可以带泛型转
org.codehaus.jackson.map.ObjectMapper
自己从网上下，用法如下：
Java code
ObjectMapper mapper = new ObjectMapper();Map<String, CityPo> tmp = mapper.readValue(json, new TypeReference<Map<String, CityPo>>() {});
[解决办法]
JAR包名是：
jackson，有两部分，一个是jackson-core-asl，一个是jackson-mapper-asl
[解决办法]
Map tmp = (Map)JSONObject.toBean(json, Map.class);  改成
Map<String,CityPo> tmp = (Map<String,CityPo>)JSONObject.toBean(json, Map.class);

这样可以吗
