无法解析org.springframework.context.ConfigurableApplicationContext类型

问题描述

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：

I am getting the following error, when i tried to create my first application in Spring Tool Suite:

这是以下pom.xml

    <?xml version="1.0" encoding="UTF-8"?>

                </plugin>
            </plugins>
        </build>
    </project>



    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);
        }
    }

可以帮助吗？我的错误是什么？在项目文件夹中显示红色感叹号。

Can any one help in this? what is my mistake? And it is showing red exclamation mark on the project folder.

推荐答案

您的maven缓存已损坏。要解决此问题，请按照以下步骤操作：

Your maven cache is corrupted. To resolve this problem, follow the steps below:

• 在命令行中转到项目目录。


• 确保您的POM.xml与命令行位于同一目录



• 运行命令

• Go to the directory of your project on the command line.
• Make sure your POM.xml is in the same directory as your command line

• Run the command

mvn dependency:purge-local-repository

如果您收到构建成功消息，表示错误已解决。

If you receive build successful message, means the error has been resolved.

如果错误仍然存​​在在那里，删除你的（〜/ .m2 / repository / org / springframework）文件夹并运行

If error is still there, delete your (~/.m2/repository/org/springframework) folder and run

mvn package

现在可以正常工作。
