我正在尝试将更大的 JSON 映射到具有嵌套对象的 Java 对象。我正在使用带有 Jersey Java 的 RESTful WS。
下面是 JSON 的示例：
JSON 现在没有用户 rootKeyPath：
{
"memberShip": {
"validTill": "2014-07-19T18:57:30Z",
"validSince": "2013-07-19T18:57:30Z"
},
"userID": "xxxxx",
"displayName": "xxxx",
"phoneNumber": "+xxx",
"country": {
"iso2DTO": "xxx",
"short_nameDTO": "xxx",
"calling_codeDTO": "+xxx",
"idNumberDTO": 009
},
"contacts": [
{
"phoneNumber": "xxxxxx",
"fullName": "xxxxx"
},
{
"phoneNumber": "xxxxxx",
"fullName": "xxxxx"
}
],
"device": {
"name": "xxxx",
"devToken": "xxxx",
"systemVersion": "x.x.x",
"model": "xxxx",
"systemName": "xxxx"
}
}
这是我的 POST 接收方法：
@Path("/user/integrate")
public class IntegrateUser {
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response createUserAccount(User user){
return Response.status(201).build();
}
}
我的用户对象：
@XmlRootElement(name = "user")
public class User {
private Integer ID;
@XmlElement(name = "displayName")
private String displayName;
@XmlElement(name = "phoneNumber")
private String phoneNumber;
@XmlElement(name = "status")
private String status;
@XmlElement(name = "userID")
private String userID;
@XmlElement(name = "country")
private Country country;
@XmlElement(name = "device")
private Device device;
@XmlElement(name = "memberShip")
private MemberShip memberShip;
@XmlElement(name = "contacts")
private List<Contact> contactsList;
/**
*
*/
public User() {
// TODO Auto-generated constructor stub
}
/**
* @return the iD
*/
public Integer getID() {
return ID;
}
/**
* @param iD the iD to set
*/
public void setID(Integer iD) {
ID = iD;
}
/**
* @return the displayName
*/
public String getDisplayName() {
return displayName;
}
/**
* @param displayName the displayName to set
*/
public void setDisplayName(String displayName) {
this.displayName = displayName;
}
/**
* @return the phoneNumber
*/
public String getPhoneNumber() {
return phoneNumber;
}
/**
* @param phoneNumber the phoneNumber to set
*/
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
/**
* @return the status
*/
public String getStatus() {
return status;
}
/**
* @param status the status to set
*/
public void setStatus(String status) {
this.status = status;
}
/**
* @return the userID
*/
public String getUserID() {
return userID;
}
/**
* @param userID the userID to set
*/
public void setUserID(String userID) {
this.userID = userID;
}
/**
* @return the country
*/
public Country getCountry() {
return country;
}
/**
* @param country the country to set
*/
public void setCountry(Country country) {
this.country = country;
}
/**
* @return the device
*/
public Device getDevice() {
return device;
}
/**
* @param device the device to set
*/
public void setDevice(Device device) {
this.device = device;
}
/**
* @return the memberShip
*/
public MemberShip getMemberShip() {
return memberShip;
}
/**
* @param memberShip the memberShip to set
*/
public void setMemberShip(MemberShip memberShip) {
this.memberShip = memberShip;
}
/**
* @return the contactsList
*/
public List<Contact> getContactsList() {
return contactsList;
}
/**
* @param contactsList the contactsList to set
*/
public void setContactsList(List<Contact> contactsList) {
this.contactsList = contactsList;
}
}
所以每次我发送这个请求时都会出现以下错误：
Jul 19, 2013 9:58:00 PM com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException
SEVERE: The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container
org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "user" (Class de.wazzuup.server.ws.model.User), not marked as ignorable
at [Source: org.apache.catalina.connector.CoyoteInputStream@228190; line: 1, column: 10] (through reference chain: de.wazzuup.server.ws.model.User["user"])
那么我做错了什么？我不确定联系人数组映射。还有关于 Xml 注释。它的 JSON，我需要注释吗？请任何建议都会很棒！
编辑1，异常堆栈跟踪：
