java - 由于缺少ServletWebServerFactory而无法启动Web服务器

我几天前看过StackOverflow。我的问题似乎很普遍。但我无法解决它。

我已经尝试过这些方法1和2。

这是我的application.propreties：

spring.datasource.driver-class-name= org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5433/mydatabase
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=create
spring.main.web-application-type=none

当我尝试运行它时，它给了我以下错误：

org.springframework.context.ApplicationContextException: Unable to start web server;
nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean

下面是我的主要课程：

@SpringBootApplication
public class StartApplication {
@Autowired
BookRepository repository;
public static void main(String[] args)
{
    SpringApplication.run(Application.class, args);
}

这是我的pom.xml：

在此先感谢您的帮助

最佳答案

您应该从application.properties文件中删除以下属性

spring.main.web-application-type=none

这意味着您的应用程序中不需要Web服务器。
