当我在列表中只收到一个项目时，我收到此错误。我在服务器端REST Web服务中使用Jersey，我只在List返回单个元素时才会收到错误，当它返回0 elements时我得到java.lang.NullPointerException但是当它有多个时它会工作完美，这就是我的方式：
@GET
@Path("getproject")
@Produces(MediaType.APPLICATION_JSON)
public List<Project> getPagedProjects(
@QueryParam("offset") int offset,
@QueryParam("limit") int limit,
@QueryParam("searchKey") String searchKey) throws Exception {
System.out.println("Returning Paged Project ");
return projectService.getPagedProjects(offset, limit, searchKey);
}
为什么Jersey不会发送包含单个项目的列表？这是球衣中的一个错误？ 有没有办法让它始终作为数组序列化？
当Web服务返回0元素时，这是我的JSON数据：
null
当Web服务返回1个元素时，这是我的JSON数据：

在android方面，我将JSON响应反序列化为：
Gson gson = new Gson();
final ProjectContainer container = gson.fromJson(resultat, ProjectContainer.class);
final ListView lv = (ListView) findViewById(R.id.list);
adaptateur = new ProjectAdapter(ProjectActivity.this, R.layout.ligne_project, container);
lv.setAdapter(adaptateur);
这是我的ProjectContainer类：
public class ProjectContainer {
@SerializedName("project")
List<Project> projects ;
public List<Project> getProjects() {
return projects;
}
public void setProjects(List<Project> projects) {
this.projects = projects;
}
}
非常感谢您帮助解决此问题。提前致谢

你的问题结果对我来说真的很奇怪......似乎泽西的单元素阵列的JSON序列化一定存在问题...如果你谷歌“ Jersey JSON单元素阵列”你会找到相同的问题，例如here或here。我不太了解泽西岛，所以我无法帮助你......
也就是说，我可以建议在Gson中使用手动解析来解决方法，使您的解析适应2种不同的响应（对象或数组）。你可以这样做：
//manually parsing until get the "project" element...
JsonParser parser = new JsonParser();
JsonObject rootObejct = parser.parse(yourJsonString).getAsJsonObject();
JsonElement projectElement = rootObejct.get("project");
Gson gson = new Gson();
List<Project> projectList = new ArrayList<>();
//Check if "project" element is an array or an object and parse accordingly...
if (projectElement.isJsonObject()) {
//The returned list has only 1 element
Project project = gson.fromJson(projectElement, Project.class);
projectList.add(project);
}
else if (projectElement.isJsonArray()) {
//The returned list has >1 elements
Type projectListType = new TypeToken<List<Project>>() {}.getType();
projectList = gson.fromJson(projectElement, projectListType);
}
//Now you have a List<Project> projectList with one or many Project elements,
//depending on the response...
请注意，您不需要课程ProjectContainer。
这样的事情应该适合你，虽然显然最好的办法是解决序列化问题！

基本上，您的网络服务在回复方面受到了打击。如果project只有一个对象，它只返回一个对象而不是一个数组。
MikO的答案解决了这个问题，但另一种方法是将该逻辑封装在自定义解串器中：
class MyDeserializer implements JsonDeserializer<ProjectContainer> {
@Override
public ProjectContainer deserialize(JsonElement je, Type type, JsonDeserializationContext jdc) throws JsonParseException {
JsonObject jo = je.getAsJsonObject().getAsJsonObject("project");
if (jo.isJsonArray()) {
return new Gson().fromJson(je, ProjectContainer.class);
} else {
Project p = jdc.deserialize(jo, Project.class);
List<Project> pList = new ArrayList<Project>(1);
pList.add(p);
ProjectContainer pc = new ProjectContainer();
pc.setProjects(pList);
return pc;
}
}
}
然后你可以使用：
Gson gson = new GsonBuilder()
.registerTypeAdapter(ProjectContainer.class, new MyDeserializer())
.build();
ProjectContainer pContainer = gson.fromJson(myJson, ProjectContainer.class);
答案 2 :(得分：0)
我最终使用Jackson library代替gson来解析json响应。它会自动将对象转换为ArrayList。就易用性而言，它与gson非常相似。希望它有所帮助！
