Java 中的 RallyApi - 尝试 return 项目层次结构的功能

Question

鉴于传递到此函数的功能结果集，我试图向上遍历项目层次结构直至订阅。我无法在 projResponse 上获得空指针 =...甚至不确定该方法。

private static void getProjHierarchyForFeature(RallyRestApi restApi, QueryResponse featureSet,
        Time2Market time2market, Integer featureInSet) {

    String tempHierarchy = "";

    JsonArray tempFeatures = featureSet.getResults();
    //time2market.setProjectName(projectName);

    try {
        JsonObject obj1 = tempFeatures.get(featureInSet).getAsJsonObject();
        JsonObject proj = obj1.get("Project").getAsJsonObject();
        String url = proj.get("_ref").getAsString();
        QueryRequest projQuery = new QueryRequest(url);
        projQuery.setFetch(new Fetch("_ref", "_refObjectUUID", "_refObjectName"));
        QueryResponse projResponse = restApi.query(projQuery);

        if (projResponse.wasSuccessful()) {
            JsonArray tempProj = projResponse.getResults();

            // Here we have the project object, now process Parents...

            Boolean moreParents = true;

            while (moreParents) {
                QueryRequest parentQuery = new QueryRequest(url);
                //projQuery.setFetch(new Fetch("_ref", "_refObjectUUID", "_refObjectName"));
                QueryResponse parentResponse = restApi.query(parentQuery);

                if (parentResponse.wasSuccessful()) {
                    System.out.println ("proj Response... " + parentResponse.toString());

                    JsonArray projParent = parentResponse.getResults();
                    tempHierarchy.concat(projParent.get(0).getAsString());
                    JsonArray tempParent = parentResponse.getResults();
                    proj = tempParent.getAsJsonObject();
                } else {
                    moreParents = false;
                }
            }
        } else {
            System.err.println("The following errors occurred: ");
            for (String err : projResponse.getErrors()) {
                System.err.println("\t" + err);
            }
            throw new java.lang.Error("Rally API Call Error Occurred");
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

}

您可能想使用 GetRequest 而不是 QueryRequest，因为您只是在读取单个对象。此外，在您的提取中包含 Parent。然后你应该有数据来确定是否有父级并继续循环。
