前天还没问题,今天启动突然就报这个错。重新从coding下载代码迟迟未能解决。服务器上却可以正常启动。什么鬼?报错如下:

启动类能加的我都加了,@EnableAutoConfiguration之前没加一样能启动,查询各种网站说加上这个即可。但无效。

package enroll.root;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Configuration;

@Configuration
@MapperScan("enroll.root.mapper")
@EnableAutoConfiguration
@SpringBootApplication

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

                            我现在只是奇怪,前天还能启动,为什么今天就不行了。什么都没变过
                        
    
                            你确定 tomcat-servlet-api 包含了所需要的 包了。你进去 spring-boot-tomcat 里面应该还有其他的吧
    
                        
    
                        我怀疑是这个'<scope>pprovided</scope>的值,在eclipse往IDEA里迁移的时候,容器的scope需要住改成compile 
                    
    
                            我把移除内嵌tomcat去掉重新加了个spring-boot-tomcat就可以启动了,真的很奇怪,pom.xml这样在测试服可以用,本地就挂,周五还能正常启动。。真的灵异事件了,我这样配置半年了项目都没问题。
                        
    
                        <p>这很明显是错误的   这样配置只能编译不能直接运行  要部署到tomcat中     现在的依赖只有servlet api没有真正的容器    不应该排除tomcat依赖</p>

                        <p>我今天也遇到了,公司电脑能正常跑,别人拉拉我的git运行就出了问题。</p> 
    

    Caused by: org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

    看你这边的解答,然后去试了一下

    IDEA注释掉之后记得要 点下右下角的 import Changes然后运行才能生效

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

    确实可以了问题解决 完美

    我怀疑是这个'<scope>pprovided</scope>的值,在eclipse往IDEA里迁移的时候,容器的scope需要住改成compile
                        <p>本地开发,注释掉<exclusions><br>                 <exclusion><br>                     <groupId>org.springframework.boot</groupId><br>                     <artifactId>spring-boot-starter-tomcat</artifactId><br>                 </exclusion><br>             </exclusions>这个就好了,</p>
