推荐答案

您的pom看起来几乎是正确的，但是没有什么要注意的

Your pom looks almost correct, but few things to note

1. 无需添加依赖项"javax.servlet-api"，可从"spring-boot-starter-web"获得它
2. 您可能会丢失"spring-boot-maven-plugin"，它不是强制性的，但您可能希望在项目中使用它.它为您提供了一些简单的Maven目标供您运行.

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

如果您正在运行日食，则可以像平常一样生成.classpath文件 mvn eclipse:eclipse ，一旦完成，您的助手就应该看起来不错

if your running eclipse you can generate your .classpath files just as usual mvn eclipse:eclipse, once done your ide should look fine

然后 mvn spring-boot:run 应将您的应用设置为运行

then mvn spring-boot:run should set your application running
