关于spring boot org.springframework.context.ApplicationContextException:Unable to start Embedded解决方案

在搭建简单的spring boot demo时使用SpringApplication来启动项目时报错：
org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

原代码：

package com.boot.web;
 
import org.springframework.boot.SpringApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class SpringBootDemoController {
    @RequestMapping
    public String helloWorld() {
        return "hello world!";
    }
    public static void main(String[] args) {
        SpringApplication.run(SpringBootDemoController.class, args);
    }
}
 

解决办法：加上@EnableAutoConfiguration注解，最好使用 jdk1.8

package com.boot.web;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@EnableAutoConfiguration
@RestController
public class SpringBootDemoController {
    @RequestMapping
    public String helloWorld() {
        return "hello world!";
    }
    public static void main(String[] args) {
        SpringApplication.run(SpringBootDemoController.class, args);
    }
}
 

修改后运行：

@EnableAutoConfiguration作用参考以下文章：
