I am using JPA in my project. I came to a query in which I need to make join operation on five tables. So I created a native query which returns five fields. Now I want to convert the result object to java POJO class which contains the same five Strings. Is there any way in JPA to directly cast that result to POJO object list ?? I came to the following solution .. @NamedNativeQueries({
我在我的项目中使用JPA。 我来到一个查询，我需要在五个表上进行连接操作。 所以我创建了一个返回五个字段的本地查询。 现在我想将结果对象转换为包含相同的五个字符串的Java POJO类。 JPA中是否有任何方法将该结果直接转换为POJO对象列表？ 我来到以下解决方案.. @NamedNativeQueries({ @NamedNativeQuery( name = "nativeSQL", query = "SELECT * FROM Actors", resultClass = d
I've got a layout with some views, from which one is an EditText. The layout easily fits on one page, BUT, when the soft keyboard is out, the layout doesn't scroll. Here's a recap of my layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_heig
我有一些有一些视图的布局，其中一个是EditText。 布局很容易放在一个页面上，但是，当软键盘出现时，布局不会滚动。 以下是我的布局回顾： <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/background" > &
I have a spring-hibernate application which is failing to map an object properly: basically I have 2 domain objects, a Post and a User . The semantics are that every Post has 1 corresponding User. The Post domain object looks roughly as follows: class Post { private int pId; private String attribute; ... private User user; //getters and setters here } As you can see, Post contai
我有一个spring-hibernate应用程序，它无法正确映射对象：基本上我有2个域对象，一个Post和一个User 。 语义是每个帖子都有一个相应的用户。 Post域对象大致如下所示： class Post { private int pId; private String attribute; ... private User user; //getters and setters here } 如您所见， Post包含对User的引用。 当我加载一个Post对象时，我想要相应的User对象被加载（懒惰 - 只在需要时）。 我的

Thanks in advance for your help. I am new to the Google developer tools and I have been messing around trying to figure out how to get one of their features to work. This one most specifically: https://developers.google.com/appengine/docs/java/tools/eclipse#Running_the_Project So this is how far I've gotten. I updated my Java package to 1.7 . I installed the Google plug in for ecli
在此先感谢您的帮助。 我对Google developer tools很陌生，并且一直在努力弄清楚如何让他们的某个功能发挥作用。 这一个最具体的： https://developers.google.com/appengine/docs/java/tools/eclipse#Running_the_Project 所以这是我得到了多少。 我更新了我的Java package to 1.7 。 我为eclipse安装了Google plug in 。 我创建了一个名为“ Guestbook ”的新项目，确保这些框被选中， run->DebugAs-> WebApp

In most cases I have a lot of components which are having the same classes to be injected by an OSGi Declarative Service. The services will be used to execute some logic which is the same for all derived components. Therefore to avoid duplicated code it would be the best to use abstract classes. Is there any possibility to move the DI reference methods (set/unset) to an abstract class. I'
在大多数情况下，我有很多组件都有相同的类被OSGi声明服务注入。 这些服务将用于执行一些逻辑，这对所有派生组件都是相同的。 因此，为避免重复代码，最好使用抽象类。 是否有可能将DI参考方法（set / unset）移动到抽象类中。 我正在使用Bnd。 例如： @Component public class B implements IA { private ServiceC sc; @Reference public void setServiceC(ServiceC sc) { this.sc = sc; } pub
What is the purpose of the dx.jar file that I see in some of Android SDK versions that I've installed with the Android SDK manager; the file appears under tools/lib/dx.jar I do NOT see the file in versions above android-8 and above. However Intellij IDEA gives an error when I try to build a project with android-8 and above, saying that dx.jar doesn't exist. What gives? Thanks, Tom
我在使用Android SDK管理器安装的一些Android SDK版本中看到dx.jar文件的用途是什么; 该文件出现在tools / lib / dx.jar下我没有在android-8及以上版本中看到该文件。 但是，当我尝试使用android-8及更高版本构建项目时，Intellij IDEA会提供错误，并说dx.jar不存在。 是什么赋予了？ 谢谢，汤姆 CommonsWare的评论之外。 dx.jar原来位于android-sdk/platforms/android-X/tools/lib/之前（特别是在android-3和android-4
