我正在创建一个单元测试来试用我刚刚创建的servlet.
@Test
public void test() throws ParseException, IOException {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://localhost:8080/WebService/MakeBaby");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("father_name", "Foo"));
nameValuePairs.add(new BasicNameValuePair("mother_name", "Bar"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = null;
try {
response = client.execute(post);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
String stringifiedResponse = EntityUtils.toString(response.getEntity());
System.out.println(stringifiedResponse);
assertNotNull(stringifiedResponse);
}
以下行生成NullPointerException:
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
有什么我想念的吗？
所以我试图用twitter bootstrap和Ryan Fait的粘性页脚创建一个布局
<body>
<div class="wrapper">
<div class="header">
</div>
<div class="user-panel">
<h1>Side Panel</h1>
</div>
<div class="content">
Hello World!
</div>
<div class="push"></div>
</div>
<div class="footer">
</div>
</body>
我似乎无法将用户面板和内容扩展到100%高度,试过这些但它们不起作用:

为简单起见(我认为); 我决定将文件压缩成一个zip文件,并在生成后提供服务.
这是我到目前为止所拥有的:
代码 ::
Button downloadLogButton = new Button("downloadlogbutton") {
private static final long serialVersionUID = 1L;
@Override
public void onSubmit() {
// Some utility class I made that zips files
LogUtility util = new LogUtility();
util.zipLogFiles("sample", logs);
}
};
Form logsForm = new Form("logsform") {
};
logsForm.add(downloadLogButton);
CheckGroup<File> checkGroup = new CheckGroup<File>("logscheckgroup", new ArrayList<File>());
WebMarkupContainer logsViewContainer = new WebMarkupContainer("datatable");
DataView<File> logsView = new DataView<File>("logrows", new ListDataProvider<File>(logs)) {
private static final long serialVersionUID = 1L;
public …我有一个服务有一个实例 BluetoothGattCallback
public class MyService extends Service {
private BluetoothGattCallback callback;
@Override
public void onCreate() {
super.onCreate();
callback = new BluetoothGattCallback() {
@Override
public synchronized void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
Log.i("onConnectionStateChanged", "Status " + status);
Log.i("onConnectionStateChanged", "New State " + newState);
}
};
}
// registration of bluetooth adapter and blah blah blah
}
当我启动应用程序时,它工作正常,回调只被调用一次,但经过几次尝试,它被调用两次.
