问题描述

我正在尝试创建一个 Spring Boot 项目.

I am trying to create a Spring Boot project.

pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.java</groupId>
  <artifactId>spring-boot-example</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>Java Spring Boot Example</name>
  <parent>  
    <groupId>org.springframework.boot</groupId>  
    <artifactId>spring-boot-starter-parent</artifactId>  
    <version>1.4.2.RELEASE</version>  
</parent>    
<dependencies>  
    <dependency>  
        <groupId>org.springframework.boot</groupId>  
        <artifactId>spring-boot-starter-web</artifactId>  
    </dependency> 

    </dependencies>  
<properties>  
    <java.version>1.8</java.version>  
</properties>  
</project>

SpringBootExample.java:

SpringBootExample.java:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication 
public class SpringBootExample {

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

尝试将上述类作为 Java 应用程序执行时，出现错误:

When trying to execute the above class as a Java application I get an error:

推荐答案

尝试添加:

        <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-tomcat</artifactId>
           <!--<scope>provided</scope>-->
        </dependency>

或者，如果您已经对此进行了评论(在这种情况下，我使用的是 Intellij 调试按钮配置)准确地说是这个项目(GitHub petClinicSpringBoot)

Or if you already have it comment this ( in this case i was using intellij debug button configuration) This project to be exact (GitHub petClinicSpringBoot)

<!--<scope>provided</scope>-->
