它仍然没有找到FXML位置。我已经搞砸了输出目录和目录以及进入FXMLLoader的URL无济于事:
Parent root = FXMLLoader.load(getClass().getResource("fxml/ui.fxml"));
这个应用程序在哪里寻找资源?

对于初学者来说,第一个问题是您的资源:
父root = FXMLLoader.load(getClass()。getResource(“fxml / ui.fxml”));
如果你使用getResource
,你必须使用绝对路径:
Parent root = FXMLLoader.load(getClass().getResource("/fxml/ui.fxml"));
StackOverflow关于这个问题有很多问题,这个answer是一个非常有效的参考。

假设你的com.potatospy.NewMain
类是launcher class,不扩展Application
,你的来源(在src/main/java/
下)是:
和你的资源(在src/main/resources
下)是:
如果你想做一个阴影/脂肪罐,而你不修改默认的maven-resources-plugin,这将只使用你的pom中的maven-compile-plugin
和maven-shade-plugin
插件:
mvn clean package
那么你可以运行你的应用程序:
java -jar target/AppName-1.0-SNAPSHOT.jar
请注意,将应用默认资源插件,并将您的文件添加到target/classes
:
Maven的资源插件
但是如果你像在pom中那样添加资源插件,当你运行它时,你会注意到你的文件被添加到:
当包完成后,fxml文件甚至没有添加到jar中!
如果你需要包含资源插件,你需要这样的东西:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<outputDirectory>${basedir}/target/classes</outputDirectory>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.fxml</include>
</includes>
</resource>
</resources>
</configuration>
<executions>
<execution>
<id>copy-resources</id>
<!-- here the phase you need -->
<phase>package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
</execution>
</executions>
</plugin>
请注意,我已将classes
添加到输出目录(因此资源包含在其中)。
