我正在使用 org.jdesktop.application 依赖项并想加载一些资源。gradle 项目的结构如下:
- main.java.myproject
- 主要资源
当我想使用getResourceMap()
. 它不读取任何属性,所以我认为这些文件必须存储在main.java.myproject.resources
. 如何设置资源映射的路径以保持我的项目结构?
代码示例:
public MyView(SingleFrameApplication app) {
super(app);
initComponents();
ResourceMap resourceMap = getResourceMap();
resourceMap.getInteger("timeout"); // <-- NullPointerException
}
