Unable to start web server; nested exception is org.springframework.context.ApplicationContextExcept

这个错误通常是由于缺少ServletWebServerFactory bean引起的。可以通过在pom.xml文件中添加以下依赖项来解决此问题:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
```
如果已经添加了此依赖项,则可能是由于端口被占用或其他配置问题导致的。可以检查端口是否被占用,或者检查应用程序的其他配置是否正确。

Unable to start web server; nested exception is org.springframework.context.ApplicationContextException
Unable to start web server; nested exception is org.springframework.context.ApplicationContextException是由于缺少ServletWebServerFactory bean引起的。这个问题通常是因为在启动类中没有正确配置注解导致的。解决方法是在启动类之前添加@EnableAutoConfiguration注解。同时,确保Controller类已经正确配置了@Controller注解,并且在主程序中使用@SpringBootApplication注解进行配置。下面是一个修正后的示例代码:
```java
@EnableAutoConfiguration
@Controller
public class HelloController {
@ResponseBody
@RequestMapping("/hello")
public String hello(){
return "hello SpringBoot!";
}
}
```
主程序:
```java
@SpringBootApplication
public class HelloApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(HelloController.class, args);
}
}
```
这样,应该就能够解决Unable to start web server的问题了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

Unable to start web server; nested exception is org.springframework.context.ApplicationContextException:
Unable to start web server; nested exception is org.springframework.context.ApplicationContextException 是一个SpringBoot项目启动报错,表示无法启动Web服务器。这个错误通常是由于缺少ServletWebServerFactory bean引起的。解决这个问题的一种方法是手动添加spring-boot-starter-tomcat依赖项,例如:
```
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<version>2.1.5.RELEASE</version>
</dependency>
```
这个依赖项将提供所需的ServletWebServerFactory bean,以解决启动错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
