我正在尝试将其解析为以下Java类 -
public class CRMAccount {
private String AccountID;
private String CRMId;
private String Name;
private CRMActivity LastActivity;
private String Owner;
private double Latitude;
private double Longitude;
private String AppointmentType;
private String RelationshipType;
private int Status;
public String getID() {
return AccountID;
}
public void setID(String accountID) {
AccountID = accountID;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public CRMActivity getLastActivity() {
return LastActivity;
}
public void setLastActivity(CRMActivity lastActivity) {
LastActivity = lastActivity;
}
public String getOwner() {
return Owner;
}
public void setOwner(String owner) {
Owner = owner;
}
public String getAppointmentType() {
return AppointmentType;
}
public void setAppointmentType(String appointmentType) {
AppointmentType = appointmentType;
}
public String getRelationshipType() {
return RelationshipType;
}
public void setRelationshipType(String relationshipType) {
RelationshipType = relationshipType;
}
public double getLatitude() {
return Latitude;
}
public void setLatitude(double latitude) {
Latitude = latitude;
}
public double getLongitude() {
return Longitude;
}
public void setLongitude(double longitude) {
Longitude = longitude;
}
public String getCRMId() {
return CRMId;
}
public void setCRMId(String cRMId) {
CRMId = cRMId;
}
}
public class CRMActivity {
private String Type;
private String Subject;
private String RegardingObjectType;
private Date StartTime;
private Date EndTime;
public CRMActivity(String type, Date dtEndTime,
Date dtStartTime, String subject)
{
this.Type = type;
this.Subject = subject;
this.StartTime = dtStartTime;
this.EndTime = dtEndTime;
this.RegardingObjectType = "account";
}
public String getType() {
return Type;
}
public void setType(String eventType) {
Type = eventType;
}
public String getSubject() {
return Subject;
}
public void setSubject(String subject) {
Subject = subject;
}
public String getRegardingObject()
{
return RegardingObjectType;
}
public Date getStartTime() {
return StartTime;
}
public void setStartTime(Date startTime) {
StartTime = startTime;
}
public Date getEndTime() {
return EndTime;
}
public void setEndTime(Date endTime) {
EndTime = endTime;
}
}
这是我用来解析JSON数据的代码 -
Gson gson = new GsonBuilder().setDateFormat(DateFormat.FULL, DateFormat.FULL).create();
CRMAccount[] lstCRMAccounts = gson.fromJson(serviceResponse.getResultMessage(),CRMAccount[].class);
这是LogCat的输出 -

答案 0 :(得分：1)
我会使用自定义反序列化器，因为你有日期解析的问题，而且因为你的类没有无参数构造函数。我的示例仅限于CRMActivity类。
public class CustomDeserializer implements JsonDeserializer<CRMActivity> {
public CRMActivity deserialize(JsonElement json, Type typeOfT,
JsonDeserializationContext context) throws JsonParseException {
if (json == null)
return null;
JsonObject jo = json.getAsJsonObject();
String type = jo.get("Type").getAsString();
String subject = jo.get("Subject").getAsString();
String endTimeAsString = jo.get("EndTime").getAsString();
String startTimeAsString = jo.get("StartTime").getAsString();
startTimeAsString = startTimeAsString.replace("/Date(", "").replace(")/", "");
endTimeAsString = endTimeAsString.replace("/Date(", "").replace(")/", "");
return new CRMActivity(type, new Date(Long.valueOf(startTimeAsString)),
new Date(Long.valueOf(endTimeAsString)), subject);
}
并以这种方式称呼它：
public class Q19657666 {
/**
* @param args
*/
public static void main(String[] args) {
GsonBuilder gb = new GsonBuilder();
gb.registerTypeAdapter(CRMActivity.class, new CustomDeserializer());
Gson g = gb.create();
String json = "{\"__type\": \"CRMService.Activity\","+
"\"Subject\": \"Call back to understand the problem (sample)\", "+
"\"Type\": \"Phone Call\", "+
"\"RegardingObjectType\": \"account\","+
"\"RegardingObjectId\": \"f3259a52-672f-e311-a7d8-d89d6765b134\","+
"\"EndTime\": \"/Date(1381226400000)/\","+
"\"Id\": \"50b79458-672f-e311-a7d8-d89d6765b134\","+
"\"StartTime\": \"/Date(1381226400000)/\"}";
CRMActivity crmActivity = g.fromJson(json, CRMActivity.class);
System.out.println(crmActivity);
}
}
你会得到这个结果：
CRMActivity [Type =电话，主题=回电以了解 问题（样本），AboutObjectType = account，StartTime = Tue Oct 08 12:00:00 CEST 2013，EndTime = Tue Oct 08 12:00:00 CEST 2013]
