一.Fastjson说明
Fastjson是一个Java语言编写的JSON处理器。
1、遵循http://json.org标准，为其官方网站收录的参考实现之一。 2、功能qiang打，支持JDK的各种类型，包括基本的JavaBean、Collection、Map、Date、Enum、泛型。 3、无依赖，不需要例外额外的jar，能够直接跑在JDK上。 4、开源，使用Apache License 2.0协议开源。http://code.alibabatech.com/wiki/display/FastJSON/Home 如果获得Fastjson？ SVN:http://code.alibabatech.com/svn/fastjson/trunk/ WIKI:http://code.alibabatech.com/wiki/display/FastJSON/Home Issue Tracking:http://code.alibabatech.com/jira/browse/FASTJSON 如果你使用了Maven，maven repository配置如下： <repository> <id>opensesame</id> <name>Alibaba OpenSource Repsoitory</name> <url>http://code.alibabatech.com/mvn/releases/</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> pom.xml文件中加入依赖依赖： <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.0.4</version> </dependency> 如果没有使用maven，可以直接下载： http://code.alibabatech.com/mvn/releases/com/alibaba/fastjson/1.0.4/fastjson-1.0.4.jar http://code.alibabatech.com/mvn/releases/com/alibaba/fastjson/1.0.4/fastjson-1.0.4-sources.jar 使用介绍： Fastjson的最主要的使用入口是com.alibaba.fastjson.JSON import com.alibaba.fastjson.JSON; public static final Object parse(String text); // 把JSON文本parse为JSONObject或者JSONArray public static final JSONObject parSEObject(String text)； // 把JSON文本parse成JSONObject public static final <T> T parSEObject(String text,Class<T> clazz); // 把JSON文本parse为JavaBean public static final JSONArray parseArray(String text); // 把JSON文本parse成JSONArray public static final <T> List<T> parseArray(String text,Class<T> clazz); //把JSON文本parse成JavaBean集合 public static final String toJSONString(Object object); // 将JavaBean序列化为JSON文本 public static final String toJSONString(Object object,boolean prettyFormat); // 将JavaBean序列化为带格式的JSON文本 public static final Object toJSON(Object javaObject); 将JavaBean转换为JSONObject或者JSONArray。
二.下面是自己写的一个工具类
1.先说下自己后台返回的json数据格式：
{"data":{"name":"吴江","state":"pass","personalIntroduction":"内科主治医师，毕业于广州医学院。","userName":"13687832930","gender":"男","city":"广州","primaryField":"擅长你内科类疾病治疗。","title":"主治医师","departmentTel":"020125689","department":"内科","hospital":"广州人民医院","userId":"06da18e65c1552e54778ec5b6ee4b41f","userFace":"http://192.169.12.94:8080/cmp/resources/images/face/0f21031469434309871.png","professionCertification":"http://192.169.12.94:8080/cmp/resources/images/certification/01d81d1469088888481.png","id":"01d81d0a3dbab77505d990061a07b9f7"},"errMsg":"","errCode":"0000"}
2.代码调用
Result result=(Result)JSON.parSEObject(resultJson.toString(),Result.class); if (result.getErrCode().trim().equals("010007")) { //error_ts.setVisibility(TextView.VISIBLE); return; } if (result.getErrCode().trim().equals("0000")) { doctorInfromation=result.getResultDataObject(DoctorInfromation.class); }
}
说明：调用getResultDataObject（）把json data部分数据转换为DoctorInfromation实例。
3.工具类代码实现：package com.youtebao.util; import java.util.List; import com.alibaba.fastjson.JSON; public class Result { private String errCode;// 是否成功标示 private String errMsg;// 描述 private String data; /*public Result(String result) { Result object=(Result)JSON.parSEObject(result,Result.class); if(object!=null) { errCode=object.errCode; errMsg=object.errMsg; data=object.data; } }*/ /** * 返回"0000"成功 * * @return */ public boolean isSuccess() { if ("0000".equals(errCode) ) { return true; return false; @SuppressWarnings("unchecked") public <T> T getResultDataObject(Class<?> parserClass) { if (data != null) { return (T) JSON.parSEObject(data,parserClass); } return null; } @SuppressWarnings("unchecked") public <T> List<T> getResultDataList(Class<?> parserClass) { if (data != null) { return (List<T>) JSON.parseArray(data,parserClass); } return null; } public String getErrMsg() { return errMsg; } public void setErrMsg(String errMsg) { this.errMsg = errMsg; } public String getErrCode() { return errCode; } public void setErrCode(String errCode) { this.errCode = errCode; } public String getData() { return data; } public void setData(String data) { this.data = data; } }说明：调用getResultDataObject返回对象，调用getResultDataList返回列表。
4.DoctorInfromation 类package com.youtebao.entity;
