从FXML加载控制器时出现IllegalArgumentException（fxmlloader.load）
因此，我正在为学校项目编码此聊天客户端，现在我需要使用JavaFX实现GUI。我已经在Scene
Builder中构建了外观简洁的GUI。现在，无论何时客户端收到一条消息，它都应该在控制器中调用一个方法，以将接收到的字符串附加到TextField上。
但是，当我尝试从FXML文件加载控制器时，出现此错误：
null/../../../../img/jim.pngjavafx.fxml.LoadException: unknown path:16at javafx.fxml.FXMLLoader.constructLoadException(FXMLLoader.java:2601)at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2579)at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2425)at com.example.main.GUI.start(GUI.java:46)at com.sun.javafx.application.LauncherImpl.lambda$launchApplication1$163(LauncherImpl.java:863)at com.sun.javafx.application.PlatformImpl.lambda$runAndWait$176(PlatformImpl.java:326)at com.sun.javafx.application.PlatformImpl.lambda$null$174(PlatformImpl.java:295)at java.security.AccessController.doPrivileged(Native Method)at com.sun.javafx.application.PlatformImpl.lambda$runLater$175(PlatformImpl.java:294)at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95)at com.sun.glass.ui.win.WinApplication._runLoop(Native Method)at com.sun.glass.ui.win.WinApplication.lambda$null$149(WinApplication.java:191)at java.lang.Thread.run(Thread.java:745)Caused by: java.lang.IllegalArgumentException: Invalid URL: Invalid URL or resource not foundat javafx.scene.image.Image.validateUrl(Image.java:1100)at javafx.scene.image.Image.<init>(Image.java:681)at com.sun.javafx.fxml.builder.JavaFXImageBuilder.build(JavaFXImageBuilder.java:47)at com.sun.javafx.fxml.builder.JavaFXImageBuilder.build(JavaFXImageBuilder.java:37)at javafx.fxml.FXMLLoader$ValueElement.processEndElement(FXMLLoader.java:763)at javafx.fxml.FXMLLoader.processEndElement(FXMLLoader.java:2823)at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2532)... 11 moreCaused by: java.lang.IllegalArgumentException: Invalid URL or resource not foundat javafx.scene.image.Image.validateUrl(Image.java:1092)... 17 more这是获取控制器并在其中调用方法的代码：
try { FXMLLoader loader = new FXMLLoader(); Pane p = loader.load(getClass().getResource("ChatForm.fxml").openStream()); ChatForm chatForm = (ChatForm) loader.getController(); chatForm.test(); } catch (IOException e) { e.printStackTrace(); }最后，我的FXML文件：
<?xml version="1.0" encoding="UTF-8"?><?import javafx.scene.text.*?><?import javafx.scene.image.*?><?import javafx.scene.control.*?><?import java.lang.*?><?import javafx.scene.layout.*?><?import javafx.scene.layout.AnchorPane?><AnchorPane prefHeight="410.0" prefWidth="300.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.example.main.ChatForm"> <children> <VBox prefHeight="410.0" prefWidth="300.0"> <children> <ImageView fitHeight="135.0" fitWidth="300.0" pickOnBounds="true" preserveRatio="true"> <image> <Image url="@../../../../img/jim.png" /> </image> </ImageView> <TextArea fx:id="chatTextArea" editable="false" focusTraversable="false" prefHeight="232.0" prefWidth="300.0" wrapText="true" /> <TextField fx:id="messageTextField" /> <Label text="Skriv ".disconnect" för att logga ut"> <font> <Font size="10.0" /> </font> </Label> </children> </VBox>加载徽标图像时显然出现了奇怪的现象。有任何想法吗？
新年快乐！
答案1
小编典典FXML文件中的语法url="@..."指的是相对于当前FXMLLoader的location属性的路径。
但是，在加载FXML文件时，您不是在向FXMLLoader位置提供信息，而是向其提供输入流。因此，位置为null和（如堆栈跟踪所示），您的路径被解释为
null /../../../../ img / jim.png要解决此问题，请将位置提供到FXMLLoader，而不是输入流：
try { FXMLLoader loader = new FXMLLoader(getClass().getResource("ChatForm.fxml")); Pane p = loader.load(); ChatForm chatForm = (ChatForm) loader.getController(); chatForm.test();} catch (IOException e) { e.printStackTrace();}假设路径实际上是正确的，这将解决当前的问题。我认为您还有其他本质上不相关的问题，因为您似乎从未对加载的场景图做任何事情（即，您从未显示窗格p）。
java.lang.IllegalArgumentException
问题描述：java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class cn.etouch.ecalendar.waterfallview.StaggeredGridView$GridListSavedState instead. This usually happens when two views of different type have the same id in the same hierarchy. This view''s id is id/lv. Make sure other views do not use the same id.
问题出现情况分析：
android 5.0及以下版本如果出现这个问题，不要以为真的是id重复了。
我的项目情况是这样的在一个activity中有四个fagment ,F1,F2,F3,F4,在F2和F3的切换过程中，F4其实也已经初始化了，我在F4的布局中使用了自定义了一个ListView，它的id为lv.
之所以报错说id相同，大约是F4的上一次状态被保留下来了。
问题解决方案：
自定义的Listview的方法重写
@Override
protected void onRestoreInstanceState(Parcelable state) {
super.onRestoreInstanceState(state); }
修改为：
@Override
protected void onRestoreInstanceState(Parcelable state) {
try {
super.onRestoreInstanceState(state);
}catch (Exception e) {}
state=null;
}
Caused by: java.lang.IllegalArgumentException: Negative time
问题
最近在部署war应用的时候，出现如下错误：
Caused by: java.lang.IllegalArgumentException: Negative time
原因
windows server 2003 在复制war文件的时候，把要被复制的文件的修改时间变成1940年。
解决
先将war在本地压缩成zip文件，然后，上传这个zip文件到服务器，然后，在服务器上面解压zip文件，这样在win上面得到war文件修改时间就没有被修改。

Hadoop启动不了Namenode进程，出现IllegalArgumentException异常
这次的问题乍看起来很奇怪，在本机完成配置启动Hadoop的时候，首先，我们需要对namenode进行format，但是在执行了命令之后，却出现了如下的异常：FATAL namenode.NameNode: Exception in namenode join java.lang.IllegalArgumentException: URI has an authority component。别的不管，就冲着这个 authority，我义无反顾地在 format命令前加上了 sudo，结果发现…………木有起到半点作用。 那么，直接跳过format环节执行start-all呢？结果看起来有点神奇，几个进程居然还都跑起来了。不过明眼一看……怪了，唯独没有namenode进程（如下图所示）。通过namenode上50070端口的 Web UI也发现无法打开网页。于是查看namenode的log文件，发现又出现了上述的IllegalArgumentException异常；而在datanode的log文件里，也发现了一大串Retrying connect to server。嗯……好吧……看来得耗上了。 经过几番查找、尝试，终于发现了问题的原因。这个异常的出现主要与这么两个文件有关：core-site.xml和hdfs-site.xml。想必进行过Hadoop配置的人对这两个文件都有着很深的印象，而这两个文件中，与本问题关系最直接的就是这么几个Property： [html] view plaincopy在CODE上查看代码片派生到我的代码片 在core-site.xml里，我们配置了hadoop.tmp.dir属性，以我这里的配置为例：hadoop.tmp.dirfile:/home/hdusr/hadoop-2.2.0/tmp/[html] view plaincopy在CODE上查看代码片派生到我的代码片 在hdfs-site.xml里，我们通过如下的方式使用了hadoop.tmp.dir的属性值（以下的写法也是Hadoop 2.2中hdfs-site的默认配置值）：dfs.namenode.name.dirfile://${hadoop.tmp.dir}/dfs/namedfs.datanode.data.dirfile://${hadoop.tmp.dir}/dfs/data这样的配置看似没有什么大的问题，而且还包含着${hadoop.tmp.dir}这种高端大气上档次的灵活性写法。但问题就出在了这里，经过实际操作确认，如果我们用这种变量式的方法对hdfs-site文件中的属性进行配置就会出现关于URI的权限问题。个人猜测可能因为Hadoop安装在hdusr目录，所以启动hadoop服务过程中，对hdfs-site文件进行载入时，解析变量式配置信息的中间过程遇到了权限问题（在下对Linux实在是菜鸟中的菜鸟，止步于此，不敢多加妄言）。。 总而言之，IllegalArgumentException出现在本人的这种配置情况中时，可以通过把hdfs-site.xml修改为如下形式解决。 [html] view plaincopy在CODE上查看代码片派生到我的代码片 为了解决这个出现的异常，我们把hdfs-site.xml中的以下两个属性修改为：dfs.namenode.name.dirfile:/home/hdusr/hadoop-2.2.0/tmp/dfs/name（即使用完整的绝对地址）dfs.datanode.data.dirfile:/home/hdusr/hadoop-2.2.0/tmp/dfs/name（即使用完整的绝对地址）进过对hdfs-site.xml文件的修改后，终于……namenode成功格式化，并且也能够正常启动Hadoop服务，启动后的进程显示见下图。 以上只是本人作为菜鸟的一些不成熟的见解，所言不实之处还请见谅，望各位高人指点，感激不尽。
html – Eclipse JavaDoc生成失败,出现IllegalArgumentException？
当我尝试为我的任何
javadoc注释类导出或生成一个javadoc时,我总是收到一个错误,直到最近它刚刚生成了完全空的html文件.

我相信它在我开始告诉向导将html文件放入我工作区中名为docs的文件夹的时候就停止了这个错误,唉这个文件夹只有一个空的html文件,名字是我项目中的一个类(通常是Stack.html或Entry.html)
此外,我遗憾地删除了TestClass类,因为它只是一个测试,但这里是我无法生成javadoc的Stack类：
/**

*/
package courseworkone;
import java.util.ArrayList;
/**

public class Stack {
/**

*/
private ArrayList<Entry> array;
/**
* The size of the Stack (The number of elements on the stack).
*/
private int size;
/**

*/
public Stack() {
array = new ArrayList<Entry>();
size = 0;
}
/**

*

*/
public final int size() {
return size;
}
/**
* Adds an element to the stack,and increases the stack size by 1.
*
* @param i

*/
public final void push(final Entry i) {
// adds the Entry to the stack
array.add(i);
// increments the stack size by one
size++;
}
/**

*
* @return the top element in the stack
*/
public final Entry top() {
// gets the element at the end of the ArrayList (top element) and
// returns it
return array.get(size - 1);
}
/**
* Returns the element on the top of the stack and then removes that element
* from the stack.
*
* @return the top element in the stack
*/
public final Entry pop() {
// stores the element at the end of the ArrayList in a temporary
// variable
Entry mostRecentEntry = array.get(size - 1);
// removes the element from the end of the ArrayList
array.remove(size - 1);
// decrements the size of the stack by one
size--;
// returns the element at the end of the ArrayList
return mostRecentEntry;
}
}
我还使用了javadoc向导将javadoc导出的设置保存为Ant脚本,以下是其内容：
