当我尝试在Spring Tool Suite中创建我的第一个应用程序时,我收到以下错误:
此行有多个标记 - 无法解析org.springframework.context.ConfigurableApplicationContext类型。它是 间接引用所需的.class文件 - 来自类型SpringApplication的run(Object,String ...)方法引用了缺少的类型 ConfigurableApplicationContext
这是以下pom.xml

This is the Controller Used
package com.welcome.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableAutoConfiguration
public class WelcomeApplication {
public static void main(String[] args)throws Exception {
SpringApplication.run(WelcomeApplication.class, args);
}
}
任何人都可以帮忙吗?我的错是什么?它在项目文件夹中显示红色感叹号。

您的maven缓存已损坏。要解决此问题,请按照以下步骤操作:
运行命令
mvn dependency:purge-local-repository
如果您收到构建成功消息,则表示错误已解决。
如果仍然存在错误,请删除您的(〜/ .m2 / repository / org / springframework)文件夹并运行
mvn package
现在可以正常使用。

将spring-boot-starter-parent更新为最新版本。为我解决了问题
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
**<version>1.3.6.RELEASE</version> // update this to latest**
<relativePath/> <!-- lookup parent from repository -->
