问题：

以编程方式运行repast simphony model时无法读取输入文件

戚哲
2023-03-14

第一次在堆栈溢出上摆姿势，所以请原谅任何遗漏的约定。让我知道，我会补救的。

我在以编程方式运行模型时遇到问题。我认为这是因为imageio无法读取jar或外部项目中的图像文件，我无法找到修复它的方法。

当我运行模型时，一切正常，但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

接着是我在阅读repast sourceforge邮件列表时认为与此无关的许多其他内容，其中他们说，GUI错误日志是需要阅读的内容。GUI中的记录器显示：

2019/03/05 09:12:32,297: Error while initializing edited style

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

这种方法：

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 () ;
    }
}

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

我已经加上了就餐时的罐子。辛菲尼。运行时_2.6.0/lib并添加了就餐。辛菲尼。运行时_2.6.0/bin文件夹到类路径。

我的目标是运行Runner项目中的多个模型

感谢您抽出时间。

问题1：您需要复制MessageCenter。log4j。属性文件保存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的已编辑样式类出现问题所致。如果使用编辑器创建显示样式并将图像文件指定给代理图标，则图像文件URL将存储在项目中的显示描述符XML文件中。rs文件夹。我怀疑XML文件中定义了图像文件的相对文件路径，如果从其他文件夹启动代码，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，或者在文件夹中创建一个符号链接，从中运行指向正确的位置。
