问题描述
这是我的 Application.java 的示例要点
Here's a sample gist of my Application.java
@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = "org.com.app.client.controller")
@EnableJpaRepositories(basePackages = "org.com.app")
@EntityScan(basePackages = "org.com.app.model")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
/**
* Spring Web MVC Confugrations
*
**/
@Bean
public ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver(){
ExceptionHandlerExceptionResolver exceptionHandlerExceptionResolver = new ExceptionHandlerExceptionResolver();
return exceptionHandlerExceptionResolver;
}
@Bean
public ViewResolver internalResourceViewResolver(){
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/jsp/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
但是，当我尝试运行我的 mvn spring-boot:run 时，总是会发生此异常.我错过了什么?
However when I try to run my mvn spring-boot:run this exception always occurs. what am I missing?

推荐答案
我找到了解决方案.我使用的 servlet 版本不正确.我使用的是 Servlet 版本 3.0.1，我已经覆盖了 spring boot 的默认 Servlet 版本，因此出现错误.
I found the solution. I was using the incorrect version of servlet. I was on Servlet version 3.0.1, I've overriden the default Servlet version of spring boot hence the error.
