Spring运行在Tomcat8.5.x上，但不是8.0.37 java.lang.NoClassDefFoundError: org/apache/coyote/UpgradeProtocol

Question

相对来说，Spring并不是什么新鲜事，所以我猜我做得不对。我一直在将一个较旧的java soap服务转换为spring。我能够在tomcat 8.5和更高版本上本地运行它，但是当我在tomcat 8.0.37上运行它(这是我要部署它的服务器)时，我会得到下面的错误。我在另一个项目中遇到了这个错误，但是在另一个项目中，我意识到我不必要地创建了一个servlet，因此，一旦我删除了servlet代码，我就很适合去做。在这种情况下，我需要创建一个servlet。错误是查找Tomcat 8.0.37中没有的"org/apache/coyote/UpgradeProtocol“。不知道我的代码中有什么在尝试使用它。如有任何建议请见谅，谢谢。

下面的配置类，我假设问题在于我如何创建我的TomcatServletWebServerFactory或ServletRegistrationBean

@ComponentScan({"com.example.exampleservices", "com.example.examplesoapservices"})
@Configuration
@EnableAWSF
public class exampleservicesConfiguration {


static {
    // Statically initialize SystemImpl so it doesn't slow down first
    // request
    try {
        SystemImpl.getInstance();
    } catch (exampleException e) {
        throw new RuntimeException(e);
    }
}

@Bean
public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
    ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new WSSpringServlet(), "/exampleservicesSOAP/*", "/exampleservicesSOAPV3/*");
    //ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new WSSpringServlet(), "/exampleservicesPort/*", "/exampleservicesPortV3/*");
    servletRegistrationBean.setEnabled(true);
    servletRegistrationBean.setLoadOnStartup(0);
    return servletRegistrationBean;
}

Answer 1

嗯，很可能是因为SpringBoot2.0系列需要释放说明中提到的Tomcat8.5。UpgradeProtocol与Tomcat8.0中不存在的HTTP2相关，所以最好的方法是在application.properties中禁用HTTP2：

server.http2.enabled=false
