Spring Boot - java.lang.IllegalStateException：ApplicationEventMulticaster未初始化

Question

刚刚创建了一个快速简单的“沙箱”应用程序来测试Spring引导。

我在尝试运行它时遇到了以下错误 - 无论版本控制如何（也尝试下降到1.4.7.RELEASE）。

此外，我在其他帖子上阅读的几乎所有答案似乎表明，某些地方的版本存在不匹配 - 但在这种情况下可能如何？我试图使用父母来避免版本冲突开始。

Answer 1

经过一番玩弄。 ..并检查其他Spring启动设置，我调整了我的ApplicationRunner如下，它似乎现在运行没有错误。我仍在研究这些方法与这个方法之间的区别。

@SpringBootApplication 
@ComponentScan("com.sandbox") 
public class BootApplicationRunner implements ApplicationRunner { 

    public static void main(String[] args) throws Exception { 

     SpringApplication.run(BootApplicationRunner.class, args); 
    } 

    public void run(ApplicationArguments args) throws Exception { 

    } 
}
