repast-simphony - 以编程方式运行 repast simphony 模型时无法读取输入文件

问题描述

第一次在堆栈溢出时摆姿势，所以请原谅任何缺少的约定。让我知道，我会纠正他们。

我无法以编程方式运行我的模型。我相信这是由于 imageio 无法读取 jar 或外部项目中的图像文件，我找不到修复它的方法。

当我正常运行模型时，一切都很好，但是当我从另一个项目以编程方式运行它时，我得到：

首先是警告：

log4j:WARN No appenders could be found for logger (org.java.plugin.boot.DefaultPluginsCollector).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

然后 GUI 启动，当我按下“开始运行”或“初始化运行”时，我得到：

Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: Caught NullPointerException: null on thread AWT-EventQueue-0

其次是我认为与这里无关的许多其他人，因为我阅读了一份就餐 sourceforge 邮件列表，他们在其中说此错误/警告 GUI 错误日志是要阅读的内容。GUI 中的记录器显示：

此错误的违规代码（在模型中）必须是：

@Override
    public Context build(Context<Object> context) {

        try {
            img = ImageIO.read(new File("maps/trondheimv2.png"));
        } catch (IOException e) {
            System.out.println(e + ": Image file not found!");
        }
        ...

我尝试过使用绝对路径：

C:/Users/USER/Documents/Git/REPO/Traffic_Main/maps/trondheimv2.png

这个方法：

getClass().getResource("C:/Users/USER/Documents/Git/REPO/Traffic_Main/maps/trondheimv2.png").toURI()));

我正在使用 FAQ 示例的重命名版本以编程方式运行模型：

package execute;

public class UserMain {
    public UserMain () {};
    public void start () {
        String [] args = new String []{ "C:/Users/USERNAME/Documents/Git/REPO/Traffic_Main/CitySim.rs"};
        repast . simphony . runtime . RepastMain . main ( args ) ;
    }
    public static void main ( String [] args ) {
        UserMain um = new UserMain () ;
        um . start () ;
    }
}

该类位于 C:/Users/USERNAME/Documents/Git/REPO/Runner/src/execute 的另一个项目中

我已经从 repast.simpony.runtime_2.6.0/lib 添加了 jar，并将 repast.simpony.runtime_2.6.0/bin 文件夹添加到类路径中。

我的目标是从 Runner 项目中运行多个模型

感谢您的时间。

编辑：进行了Eric Tatara建议的更改并得到以下错误：

解决方案

问题 1：您需要将 MessageCenter.log4j.properties 文件复制到运行模型的文件夹中。

问题 2：您发布的异常表明错误是由于其中一个显示器的已编辑样式类出现问题。如果您使用编辑器创建显示样式并将图像文件分配给代理图标，则图像文件 URL 将存储在位于项目 .rs 文件夹中的显示描述符 XML 文件中。我怀疑图像文件的相对文件路径是在 XML 文件中定义的，如果您从另一个文件夹启动代码，则相对路径将不正确。我建议直接编辑样式 XML，或者使用绝对路径，或者相应地更改相对路径，或者在您的运行指向正确位置的文件夹中创建一个符号链接。
