For testing/benchmarking purposes, I want to write a Java program that does the following tasks in a loop: load data via HTTP GET from a server ( generate an answer based on the received data - not important at this point ) send the answer via HTTP POST to the same server This cycle runs on multiple threads at the same time. After having started, the program runs fine for a short period
为了测试/基准测试的目的，我想编写一个Java程序，在循环中执行以下任务： 通过HTTP GET从服务器加载数据 （根据收到的数据生成一个答案 - 在这一点上不重要） 通过HTTP POST将答案发送到同一台服务器 此循环同时在多个线程上运行。 启动后，程序在短时间内运行良好，并且能够每秒执行约300个循环（网络服务器在同一台机器上运行）。 但5-7秒后，我得到BindException: Address already in use 。 在20-30秒冷却时间
I've been profiling the x64 version of my application as the memory usage has been outrageously high, all of it seems to be coming from the JavaFX MediaPlayer, i'm correctly releasing listeners and eventhandlers. Here is the stark contrast. The x32 version at start And now the x64 version at start The x32 version stays below 256mb while the x64 will shoot over a gig; this is whil
我一直在分析我的应用程序的x64版本，因为内存使用率一直很高，所有这些似乎都来自JavaFX MediaPlayer，我正确地释放了监听器和事件处理程序。 这是鲜明的对比。 开始时的x32版本 现在在x64版本开始 x32版本保持在256mb以下，而x64会在一个演出中拍摄; 这是两个人都要通过他们的播放列表播放。 所有的代码都是一样的。 JDK：jdk1.8.0_20 JRE：jre1.8.0_20 VM上的参数 -XX:MinHeapFreeRatio=40 -XX:MaxHeapFreeR
I have a directory which another process throws files into. Our current implementation of Storm reads this directory and selects the oldest file and opens a reader to the file. This reader is held as a field within the spout so when nextTuple() is called, a single line is output from the file. Once the spout has finished reading it closes the reader and opens a new reader to a new file. To
我有另一个进程抛出文件的目录。 我们目前的Storm实现读取这个目录并选择最旧的文件并打开一个阅读器到文件。 该阅读器作为喷口内的字段保存，因此当调用nextTuple（）时，将从该文件输出一行。 一旦喷口完成读取，关闭读取器并将新读取器打开到新文件。 为了提高吞吐量，一个想法是让多个喷口一次读取多个文件，因为这些喷口将争夺相同目录中的相同文件，是否有方法在喷口之间进行通信，以便他们可以协商读取哪些文件？
Regarding this question, I checked out Spring Data Rest Ambiguous Association Exception but couldn't get it to work for me. As you can see in my code below, I added @RestResource annotation with rel equal to some other value. Similar to the question above, POST requests work, but GET requests throw exception about multiple association links with the same relation type: "Could not w
关于这个问题，我查了一下Spring Data Rest Ambiguous Association Exception，但是无法为我工作。 正如你可以在下面的代码中看到的，我添加了@RestResource注释，其中rel等于其他值。 与上面的问题类似，POST请求可以工作，但GET请求会抛出具有相同关系类型的多个关联链接的异常： “无法写入JSON：检测到具有相同关系类型的多个关联链接！消除关联@ org.springframework.data.rest.core.annotation.RestResource（rel = c
I need to instantiate a prototype bean which has multiple constructors with arguments and Autowired injections. I started with the solution found here to instantiate the bean: Spring bean with runtime constructor arguments Bean Definition public MyBean { @Autowired private MyService myService public MyBean(int a1, String a21, String a22) { } public MyBean(int a1, String[] a
我需要实例化一个具有带参数和自动布线注入的多个构造函数的原型bean。 我从这里找到的解决方案开始实例化bean：带有运行时构造函数参数的Spring bean Bean定义 public MyBean { @Autowired private MyService myService public MyBean(int a1, String a21, String a22) { } public MyBean(int a1, String[] a2, int a3) { } public void exampleCallService(int value) { myService.remote
I am using lookup method injection in Spring 3 to inject a prototype bean into a singleton bean as described in the Spring docs here. Inside my prototype bean I have an @Autowired dependency on another bean declared in my applicationContext.xml. The lookup method injection seems to be working properly in that my prototype bean is being injected into my singleton bean, however, the prototype'
我在Spring 3中使用查找方法注入来将原型bean注入单例bean，如Spring文档中所述。 在我的原型bean中，我有一个@Autowired依赖于在applicationContext.xml中声明的另一个bean。 查找方法注入似乎正在正常工作，因为我的原型bean被注入到单例bean中，但是，原型的依赖关系根本没有被注入。 当原型通过查找方法返回时，依赖关系是否可以以正常方式注入到原型bean中？ 如果没有，那么做这件事的首选方法是什么？ 编辑 ：这个be
I am reading the spring 3.0.x reference documentation to understand Spring Autowired annotation: 3.9.2 @Autowired and @Inject I am not able to understand the below examples. Do we need to do something in the XML for it to work? EXAMPLE 1 public class SimpleMovieLister { private MovieFinder movieFinder; @Autowired public void setMovieFinder(MovieFinder movieFinder) {
我正在阅读Spring 3.0.x参考文档以了解Spring Autowired注释： 3.9.2 @Autowired和@Inject 我无法理解下面的例子。 我们是否需要在XML中进行一些操作？ 例1 public class SimpleMovieLister { private MovieFinder movieFinder; @Autowired public void setMovieFinder(MovieFinder movieFinder) { this.movieFinder = movieFinder; } // ... } 例2 public class MovieRecommender {
I'm trying to inject a java.util.prefs.Preferences bean in to my master controller. The controller looks like: @Controller class MyController { @Autowired private Preferences preferences; } The application-context.xml file creates the bean for java.util.prefs.Preferences. It uses a factory method so I have the following entry for creating the bean: <bean id="preferences" class
我试图将一个java.util.prefs.Preferences bean注入到我的主控制器中。 控制器看起来像： @Controller class MyController { @Autowired private Preferences preferences; } application-context.xml文件为java.util.prefs.Preferences创建一个bean。 它使用工厂方法，所以我有以下条目来创建bean： <bean id="preferences" class="java.util.prefs.Preferences" factory-method="userNodeForPackage" /> P
Spring's DI works fine for singleton scope bean. However, regarding to prototype scope it is not convenient if the prototype bean itself will inject other beans. The thing is for prototype bean, I would like to create them using new keyword of Java with runtime constructor arguments which is hard to be statically described in XML bean configuration. Using new keyword makes the prototype be
Spring的DI对singleton scope bean工作正常。 但是，关于原型范围，如果原型bean本身会注入其他bean，这并不方便。 关于原型bean，我想用Java的new关键字创建它们，并且运行时构造函数参数很难在XML bean配置中静态描述。 使用新的关键字使得Spring容器中的prototype bean变得不可用，当然不可能在其中使用Spring DI。 我想知道人们是如何解决这样的问题的？ 当然，我可以使用AspectJ来做自己的注射作为补偿。 但有两种注
I am trying to achieve lookup method injection using a simple example. But, seems to fail in getting the bean injected via the method. I have a simple bean namely; DemoBean as below: public class DemoBean { private String message; public DemoBean() { } public DemoBean(String message) { this.message = message; } // Getter and Setter methods @Override
我试图用一个简单的例子来实现查找方法注入。 但是，似乎无法通过该方法注入bean。 我有一个简单的bean; DemoBean如下： public class DemoBean { private String message; public DemoBean() { } public DemoBean(String message) { this.message = message; } // Getter and Setter methods @Override public String toString() { return "DemoBean{" +
