我使用Maven开发Spring应用程序。我在尝试启动应用时遇到错误。我猜问题是我的POM文件。也许错过了一些依赖关系或者我犯了错误。不幸的是，我无法理解自己的错误。 这是我的AppLoader类：

package com.boris.getandsend.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.scheduling.annotation.EnableScheduling;

@EnableScheduling
@SpringBootApplication
public class AppLoader extends SpringBootServletInitializer {


@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(AppLoader.class);
}

public static void main(String[] args) throws Exception {
    SpringApplication.run(AppLoader.class, args);
}
}

这是我的POM文件。

希望你能帮助我！提前谢谢。

答案 0 :(得分：1)

我自己找到了解决方案。 首先需要使用最新版本的spring-boot-starter-parent。 比需要使用这一行： import org.springframework.boot.web.support.SpringBootServletInitializer;

如下所示： import org.springframework.boot.context.web.SpringBootServletInitializer;

现在一切正常。
