解析json字符串時，無法識別的字段（未標記為可忽略）

Question

我正在從事澤西島的休息服務。 嘗試將通用對象（在我的情況下為AppObject）作為后期請求傳遞，並且服務器的響應也是通用對象（在我的情況下為AppObject），我期望一個字符串{"license":"12345","list":[{"alternateId":"AlternateID","classificati‌​on":"1"}] }但由於列表的原因，我得到了dimRequirement ，如下所示。 因此，在解析json時會遇到異常。 有沒有一種方法可以將其作為列表本身而無需更改代碼。 或任何其他方式可以幫助我。

客戶端接收Json字符串

{"license":"12345","dimRequirement":[{"alternateId":"AlternateID","classificati‌​on":"1"}] }

我的客戶

AppObject<DimRequirement> appObject = new AppObject<DimRequirement>();
        appObject.setClientKey(4L);
        Client client = Client.create();
        WebResource webResource = client
                   .resource("http://localhost:8080/myproject/");

        JSONObject json = new JSONObject(appObject);
        ClientResponse response = webResource.path("rest").path("requirement/getreq").type("application/json").accept("application/json")
                .post(ClientResponse.class,json.toString());
        String output = response.getEntity(String.class);
        System.out.println(output);
        appObject= new ObjectMapper().readValue(
                output, AppObject.class);

錯誤

通用類

@XmlRootElement
@XmlSeeAlso({DimRequirement.class })
public class AppObject<T> implements Serializable {

    private List<T> list;
    private Long clientKey;

    public AppObject() {
        list = new ArrayList<T>();

    }

    public AppObject(List<T> list) {
        this.list = list;
    }

    @XmlAnyElement(lax = true)
    public List<T> getList() {
        return list;
    }

    public void setList(List<T> list) {
        this.list = list;
    }

    public Long getClientKey() {
    return clientKey;
}

public void setClientKey(Long clientKey) {
    this.clientKey = clientKey;
}

}

服務

@Path("/requirement")
public class DimRequirementManagerImpl {
@POST
    @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    @Path("/getreq")
    @Override
    public AppObject getAllByClientNIsCurrent(
            AppObject<DimRequirement> appObj) {
        List<DimRequirement> dimreqlist = dimRequirementDao
                .getAllByClientNIsCurrent(appObj.getClientKey());
        AppObject appObject = new AppObject();
        appObject.setList(dimreqlist);
        return appObject;
    }}

設置為AppObject的DimRequirement

@XmlRootElement
public class DimRequirement extends BaseObject implements Serializable {
private Long requirementKey;
private String description;
private String priority;
@Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="requirementKey")
    public Long getRequirementKey() {
        return this.requirementKey;
    }    
    public void setRequirementKey(Long requirementKey) {
        this.requirementKey = requirementKey;
    }
 @Column(name="Description") 
    public String getDescription() {
        return this.description;
    }    
    public void setDescription(String description) {
        this.description = description;
    }
 @Column(name="Priority") 
    public String getPriority() {
        return this.priority;
    }    
    public void setPriority(String priority) {
        this.priority = priority;
    }
}

我已將服務的返回類型更改為string（json string）。

服務

@Path("/requirement")
public class DimRequirementManagerImpl {
@POST
@Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
@Path("/getreq")
@Override
public String getAllByClientNIsCurrent(AppObject<DimRequirement> appObj) {
try {
     List<DimRequirement> dimreqlist = dimRequirementDao.getAllByClientNIsCurrent(appObj.getClientKey());
     AppObject appObject = new AppObject();
     appObject.setList(dimreqlist);
     JSONObject jsonget = new JSONObject(appObject);
     return jsonget.toString();
     }catch (Exception e) {
        AppObject<DimRequirement> appObject = new AppObject<DimRequirement>();
        appObject.setLicense("12345");
        JSONObject jsonget = new JSONObject(appObject);
        return jsonget.toString();
    }
}}

這對問題returnig json {“ license”：“ 12345”，“ list”：[{“ alternateId”：“ AlternateID”，“ classificati‌on”：“ 1”}]}的同一客戶有效
