使用 'mvn spring-boot:run' 启动 JavaFX Spring 项目

Question

如何使用maven来启动一个spring-boot项目，该项目扩展了不包含主方法的javafx.application.Application？每次我尝试用maven启动它时，都会显示下面的错误。

错误消息：

[错误]无法执行目标org.springframework.boot:spring-boot maven插件：2.0.5。发布：在项目聊天客户端上运行(默认cli(：运行时发生异常。指定的mainClass不包含具有适当签名的main方法。：XX、 XXX.ChatClient.main([Ljava.lang.String；(->[Help 1]

Answer 1

替换：

<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>${start-class}</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>

带有：

<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

不需要指定mainClass。

这里有一个完整的例子。

更新

现在我注意到你没有一个主要的方法。将此代码添加到ChatClient类：

public static void main(String[] args) {
Application.launch(ChatClient.class, args);
}
