是否tomcat7-maven-plugin使用tomcat 8服务器和java 8？我找不到任何东西tomcat8-maven-plugin.

我如何java.lang.Iterable从一个Set或一个集合中获得一个List？谢谢!

我们使用spring,jpa,tomcat,maven等开发应用程序.

在我的开发人员机器上本地一切正常,但当我们在Linux服务器上部署应用程序时,我得到以下异常:

我在Mockito有这个:

when(mockedMergeContext.createNewEntityOfType(IService.class)).thenReturn(new ServiceMock());

该createNewEntityOfType方法应始终返回一个新ServiceMock实例,但它返回两次相同的引用.

为什么该thenReturn方法不返回新的ServiceMock？

我可以在play 2.1中的子目录中组织我的视图模板吗？

如果我有这样的结构,我会收到编译器错误: app/views/common/component.scala.html

谢谢!

我正在寻找一个可以衍生和合并XML文件的开源版本控制工具.

我必须找到这样一个工具的难点是,我需要正确合并XML文件,比较节点而不是行.

任何的想法？谢谢!

我尝试在播放视图模板中使用一个函数

@active(path: String):String = @{
       var active:String = ""
       if (request.path.startsWith(path)) {
           active = "class=\"active\""
       } 
       return active
}

<div class="container-fluid">
....
    <li @active("/page") ...>

播放编译器说它找不到活动的值.这有什么不对？

我正在尝试对我的playframework jave代码进行声纳分析.没有索引的文件:

我正在寻找一个快速算法,它给出了BitSet对象中设置位的所有索引.这很慢:

BitSet bitSet = ...
Collection<Integer> indexes = new ArrayList<Integer>(bitSet.cardinality());
int nextSetBit = bitSet.nextSetBit(0);
for (int i = 0; i < bitSet.cardinality(); ++i ) {
    indexes.add(nextSetBit);
    nextSetBit = bitSet.nextSetBit(nextSetBit + 1);
}
...

任何帮助表示赞赏!

I was wondering if it is possible to have a RESTful web service and a bidirectional communication with the clients and server.

In my case the state on the server can change, so the server should send a message to the clients to update themself. Perhaps that's totally against the RESTful idea.

Can I AJAX help me with this issue?

Thanks!
