我将我的Android应用程序与我的WildFly 10x服务器连接有点问题，我搜索了一段时间，但没有解决方案来解决我的问题。 请注意我使用以下IP： 我的Localhost-Address：http://127.0.0.1:8080/（在此运行我的服务器） 我的本地IP地址 和我Mac上的IP地址
如果我立即使用Mac上的IP-Adress和应用崩溃的本地主机，但如果我使用本地IP地址，应用程序崩溃几次。
首先是我的WildFly服务器代码：
我的CrudAccessor
@Path("/todos")
@Consumes({ "application/json" })
@Produces({ "application/json" })
public interface TodoModelCrudAccessor {
@GET
@Produces({ "application/json" })
public ArrayList<TodoModel> readAllTodos();
@POST
public TodoModel createTodo(TodoModel todo);
@DELETE
@Path("/{todoId}")
public boolean deleteTodo(@PathParam("todoId") Integer todoId);
@PUT
public TodoModel updateTodo(TodoModel todo);
@POST
@Path("/login")
public boolean checkLoginData(Login loginData);
我只实现了readAllTodos函数来测试服务器
@Override
public ArrayList<TodoModel> readAllTodos() {
todolist.add(new TodoModel(1, "Ernie", "MeineBeschreibung", 0, 0, 0, 123));
todolist.add(new TodoModel(2, "Bert", "sdfg", 1, 1,0 , 123124));
return todolist;
}
我的RestService
@ApplicationPath(value="/rest/*")
public class RemoteDataAccessRESTService extends javax.ws.rs.core.Application {
protected static Logger logger = Logger.getLogger(RemoteDataAccessRESTService.class);
public RemoteDataAccessRESTService() {
logger.info("<Constructor>()");
}
}
我的Android应用程序：
ServerRemoteAccessor接口
@Path("/todos")
@Consumes({ "application/json" })
@Produces({"application/json"})
public interface IServerRemoteAccessor {
@GET
@Produces({"application/json"})
public ArrayList<TodoModel> readAllTodos();
@POST
public TodoModel createTodo(TodoModel todo);
@DELETE
@Path("/{todoId}")
public boolean deleteTodo(@PathParam("todoId") long itemId);
@PUT
public TodoModel updateTodo(TodoModel todo);
}
ServerRemoteAccessor Class
public class ServerRemoteAccessor implements IServerRemoteAccessor {
private static final String LOG_TAG = ServerRemoteAccessor.class.getName();
private IServerRemoteAccessor client;
private String baseURL;
private BasicHttpParams params;
public ServerRemoteAccessor(String baseURL){
if (baseURL != null) {
this.baseURL = baseURL;
params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET);
HttpProtocolParams.setUseExpectContinue(params, false);
this.client = ProxyFactory.create(IServerRemoteAccessor.class, baseURL, new ApacheHttpClient4Executor());
}
// createClient();
}
public IServerRemoteAccessor createClient(){
this.client = ProxyFactory.create(IServerRemoteAccessor.class, baseURL, new ApacheHttpClient4Executor());
return client;
}
//Implementierung der CRUD-Operationen
@Override
public ArrayList<TodoModel> readAllTodos(){
Log.i(LOG_TAG, "readAllTodos");
ArrayList<TodoModel> todoList = client.readAllTodos();
Log.i(LOG_TAG, "readAllTodos: " + todoList);
return todoList;
}
这就是我连接到我的服务器并希望阅读所有待办事项的方式
try {
serverRemoteAccessor = new ServerRemoteAccessor("http://192.168.188.82:8080/DataAccessRemoteWebapp/rest");
new AsyncTask<Void, Void, ArrayList<TodoModel>>() {
@Override
protected ArrayList<TodoModel> doInBackground(Void... voids) {
return serverRemoteAccessor.readAllTodos();
}
@Override
protected void onPostExecute(ArrayList<TodoModel> todoModels) {
todoList.addAll(todoModels);
}
}.execute();
} catch (Exception e){
Log.e(LOG_TAG, "Error: " + e);
}
这是我的错误讯息：
