Springboot应用不能用main方法启动

Question

使用mvn spring-boot:run可以正常启动
但是通过main方法（即intellij IDEA的小三角启动）
进程会直接关掉：
log信息如下：

同时也配置了以下这个类：

package com.tongji409;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

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

}

Answer 1

main方法的类上有个注解!注解!

Answer 2

你应该在类上加上 @SpringBootApplication 注解并且写一个main 方法 内容：

 SpringApplication.run(ServletInitializer.cless,args);

Answer 3

我遇到了同样的问题。
只需要把spring-boot-starter-tomcat这个包去掉就可以了。springboot有内置的tomcat

@任意666

Answer 4

依赖里面有一个tomcat的依赖
providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
providedRuntime 只会在runtime才会依赖进来，改成编译时依赖就好了
改成下面这样：
compile('org.springframework.boot:spring-boot-starter-tomcat')
当然，还至少添加一个controller才可以
maven的 应该去掉依赖的scop就可以了吧

Answer 5

我遇到了同样的问题,将tomcat依赖项的scope注释掉就可以了
`<dependency>

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

</dependency>`

Answer 6

你好 请问你解决了吗 我也出现这个问题了

Answer 7

Springboot项目两周启动方式

方式一：通过main方法启动，便于开发，

@SpringBootApplication
public class ConsoleMain{

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

方式二：通过Web容器，如Tomcat启动的入口类

@Configuration
public class ConsoleWeb implements WebApplicationInitializer {
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(new Class[] { SpringMvcConfig.class });
        context.setServletContext(servletContext);
        ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(context));
        servlet.addMapping(new String[] { "/" });
        servlet.setLoadOnStartup(1);
    }
}

Spring和Springmvc配置类

@Configuration
@EnableWebMvc
@ComponentScan({"com.zccoder.hello"})
public class SpringMvcConfig
  extends WebMvcConfigurerAdapter
{}
