没有为类org.json.JSONObject找到序列化程序，也没有发现创建BeanSerializer的属性

从Web服务获得JSON，Json Array作为响应

[3] 0: { id: 2 name: "a561137" password: "test" firstName: "abhishek" lastName: "ringsia" organization: "bbb" }- 1: { id: 3 name: "a561023" password: "hello" firstName: "hello" lastName: "hello" organization: "hello" }- 2: { id: 4 name: "a541234" password: "hello" firstName: "hello" lastName: "hello" organization: "hello" } 

在JsonArray中获取响应之后在读取Json数组的Json对象时获取错误：

 List list = new ArrayList(); JSONArray jsonArr = new JSONArray(response); for (int i = 0; i < jsonArr.length(); i++) { JSONObject jsonObj = jsonArr.getJSONObject(i); ObjectMapper mapper = new ObjectMapper(); User usr= mapper.convertValue(jsonObj, User.class); list.add(usr); } 

没有为类org.json.JSONObject找到序列化程序，也没有发现创建BeanSerializer的属性（为了避免exception，请禁用SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS））

必须首先接受它作为Json数组，然后在读取它的Object时必须使用Object Mapper.readValue，因为Json Object仍然在String中。

 List list = new ArrayList(); JSONArray jsonArr = new JSONArray(response); for (int i = 0; i < jsonArr.length(); i++) { JSONObject jsonObj = jsonArr.getJSONObject(i); ObjectMapper mapper = new ObjectMapper(); User usr = mapper.readValue(jsonObj.toString(), User.class); list.add(usr); }
