java杰克逊：从url rest网络服务获取作为json的pojo（带有内部pojo），并将其映射回pojo

Question

I'm using jackson, the scenario is:

1. In client (Android) generate url call to web service
2. The web service return "complex pojo" (has class members as other pojo) as json
3. Back in client map the json to pojo

I don't know how to complete this code to get things work although I searched all over and figured out the following start point, but then I completely stacked and I need help...

1. The "complex pojo":

    public class MyPojo { private List<MyOtherPojo> myOtherPojo; private List<HashMap<String, String>> listOfMaps; private Map<String, String> map; //Constructors, getters & setters } 

2. The code at client:

    String wsURI = "server.com/myservice?param1=a&param2=b"; try { URL url = new URL(wsURI); URLConnection connection = url.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); StringBuilder sbuilder = new StringBuilder(); String aux = ""; while ( (aux = in.readLine()) != null) { sbuilder.append(aux); } ObjectMapper mapper = new ObjectMapper(); //TODO get myPojo object from his representation as string at sbuilder.toString(); myPojo = ???; } catch (Exception e) {}

解决方案感谢@peeskillet：

MyPojo myPojo = mapper.readValue(connection.getInputStream(), MyPojo.class);
