能不能给个和Spring集成的例子呢？
比如像Jackson这样的？ org.springframework.web.servlet.view.json.MappingJacksonJsonView 通过代理配置能实现使用 fastJSON 序列化 返回集？ 谢谢～ |

struts2中如何使用？能否直接替换struts2-json-plugin这样的东西，而在使用过程中依旧通过struts提供的annotation result type="json"方式？

Map<Object, Object> map = JSON.parseObject("{1:\"2\",\"3\":4,'5':6}", new TypeReference<Map<Object, Object>>() {});
Assert.assertEquals("2", map.get(1));
Assert.assertEquals(4, map.get("3"));
Assert.assertEquals(6, map.get("5"));

我在项目中用到了fastjson1.1.1，最近测试了1.1.5，1.1.6，遇到两个问题，麻烦温少给看看：
1.速度下降很多，对size为100的list序列化5000次，用JACKSON耗时982，fastjson1.1.1耗时967，fastjson1.1.6耗时3225 2.反序列化出错，jackson和fastjson都没有问题，1.1.5和1.1.6都会出现异常 java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType 代码如下： public class User implements Serializable{ private String user_id = "aaaa"; Date bri; Timestamp bri2; Double num; List list; ... } 序列化 for(int i=0; i<count; i++){ json = JSON.toJSONString(list); } 反序列化 List<User> tt = JSON.parseArray(json, User.class); |
