用这个api有时候会报错,基本上是因为包没引入完,

引入这几个包后基本上没什么问题,

但是对于JSONObject.fromObject 和 SONObject.toBean的使用为:

String strTmp = "{\"errmsg\":\"ok\",\"ErrorCode\":0,\"messageId\":\"f5d4566c4c833152b3feb42a8092ee6c\",\"invaliduser\":\"\",\"forbiddenUserId\":\"\",\"resJson\":{\"errmsg\":\"ok\",\"ErrorCode\":0,\"messageId\":\"f5d4566c4c833152b3feb42a8092ee6c\",\"invaliduser\":\"\",\"forbiddenUserId\":\"\"}}";    JSONObject jb = JSONObject.fromObject(strTmp);    Map<String, Object> resmap = (Map<String, Object>)jb;System.out.println("-----resmap:---"+resmap.toString());  String json = "{id:'1001',name:'张三',age:'22'}";        student stu = new student();        JSONObject obj = JSONObject.fromObject(json);        stu = (student)JSONObject.toBean(obj, student.class);        System.out.println(stu);

package bao;public class student {    private int id ;    private String name;    private int age;        public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }        public String toString(){        return this.id + ",==== " + this.name + ", " + this.age;    }}

结果为:

-----resmap:---{"errmsg":"ok","ErrorCode":0,"messageId":"f5d4566c4c833152b3feb42a8092ee6c","invaliduser":"","forbiddenUserId":"","resJson":{"errmsg":"ok","ErrorCode":0,"messageId":"f5d4566c4c833152b3feb42a8092ee6c","invaliduser":"","forbiddenUserId":""}}
