有时候可能会用到json格式进行数据的传输，那么怎么把接收到的数据解析出来呢？ 下面介绍两种解析json数据的方法：
1、通过谷歌的Gson来进行解析：
json数据：sTotalString = {"message":"success","result":[{"surveyid":"1","surveyname":"B"}{surveyid":"2","surveyname":"C"}]};
两个VO类：
public class SurveyVO {
private String surveyId;
private String surveyName;
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getSurveyId() {
return surveyId;
}
public void setSurveyId(String surveyId) {
this.surveyId = surveyId;
}
public String getSurveyName() {
return surveyName;
}
public void setSurveyName(String surveyName) {
this.surveyName = surveyName;
}
}
public class SurveyListVO {
private String message;
private List<SurveyVO> result;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public List<SurveyVO> getResult() {
return result;
}
public void setResult(List<SurveyVO> result) {
this.result = result;
}
}
json格式转换成object类型：
public class fromGson() {
sTotalString = {"message":"success","result":[{"surveyid":"1","surveyname":"B"}{"surveyid":"2","surveyname":"C"}]};
Gson gson = new Gson();
SurveyListVO surveyListVO = gson.fromJson(sTotalString,
SurveyListVO.class);
for (int i = 0; i < surveyListVO.getResult().size(); i++) {
System.out.print(surveyListVO.getResult().get(i)
.getSurveyId());
print: 1////2
System.out.print(surveyListVO.getResult().get(i)
.getSurveyName());
print: B///C
System.out.print(surveyListVO.getMessage());
}
}
2、通过json-org.jar包进行解析：
json数据：sTotalString = {"message":"success","result":[{"surveyid":"1","surveyname":"B"}{surveyid":"2","surveyname":"C"}]};
一个VO类：
public class SurveyVO {
private String surveyId;
private String surveyName;
public String getSurveyId() {
return surveyId;
}
public void setSurveyId(String surveyId) {
this.surveyId = surveyId;
}
public String getSurveyName() {
return surveyName;
}
public void setSurveyName(String surveyName) {
this.surveyName = surveyName;
}
}
json格式转换成object类型：
public class fromJson() {
sTotalString = {"message":"success","result":[{"surveyid":"1","surveyname":"B"}{"surveyid":"2","surveyname":"C"}]};
JSONObject json;
try {
json = new JSONObject(sTotalString);
JSONArray results = json.getJSONArray("result");
for (int i = 0; i < results.length(); i++) {
SurveyVO surveyVO = new SurveyVO();
JSONObject result = results.getJSONObject(i);
System.out.println(result.getString("surveyId")+" "+result.getString("surveyName"));
surveyVO.setSurveyId(result.getString("surveyId"));
surveyVO.setSurveyName(result.getString("surveyName"));
surveyVOList.add(surveyVO);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
