java.lang.IllegalArgumentException：无法注册名为'dispatcher'的servlet . 检查是否有另一个以相同名称注册的servlet

My initializer class

public class HomeServlet extends 
AbstractAnnotationConfigDispatcherServletInitializer{

@Override
protected Class<?>[] getRootConfigClasses() {

    return null;
}

@Override
protected Class<?>[] getServletConfigClasses() {

    return new Class<?>[]{SpringContextConfig1.class};
}

@Override
protected String[] getServletMappings() {

    return new String[] {"/home"};
}

}

Configuration Class

@ComponentScan(basePackages={"spittr.controllers"})
@Configuration
@EnableWebMvc
public class SpringContextConfig1 extends WebMvcConfigurerAdapter{

@Bean
public ViewResolver getViewResolver(){
    InternalResourceViewResolver ivr=new InternalResourceViewResolver();
    ivr.setPrefix("/WEB-INF/jsp/");
    ivr.setSuffix(".jsp");
    ivr.setExposeContextBeansAsAttributes(true);
    return ivr;
}

}

Controller

@Controller
public class HomeController {


@RequestMapping(value="/home",method=RequestMethod.GET)
public String home(){
    return "home";
}

}

这是一个非常简单的程序，我编写了测试Spring MVC的JavaConfig . 我完全按照“Spring in Action”一书中的所有步骤进行操作 .

当我运行此代码时，我收到此错误

09：41：37,854 ERROR [org.jboss.msc.service.fail]（ServerService线程池 - 72）MSC000001：无法启动服务jboss.undertow.deployment.default-server.default-host./spittr：org服务中的.jboss.msc.service.StartException.jboss.undertow.deployment.default-server.default-host . / spittr：java.lang.RuntimeException：java.lang.IllegalArgumentException：无法注册名为'dispatcher'的servlet . 检查如果有另一个以相同名称注册的servlet . at org.wildfly.extension.undertow.deployment.UndertowDeploymentService $ 1.run（UndertowDeploymentService.java:85）at java.util.concurrent.Executors $ RunnableAdapter.call（Executors.java:511）at java.util.concurrent.FutureTask . java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1142）在java.lang.Thread的java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:617）上运行（FutureTask.java:266） .run（Thread.java:745）at org.jboss.threads.JBossThread.run（JBossThread.java:320）引起：java.lang.RuntimeException：java.lang.IllegalArgumentException：无法注册名为'dispatcher'的servlet . 检查是否有另一个以相同名称注册的servlet . 在org.wildfly.extension.undertow.deployment的org.wildfly.extension.undertow.deployment.UndertowDeploymentService.startContext（UndertowDeploymentService.java:100）的io.undertow.servlet.core.DeploymentManagerImpl.deploy（DeploymentManagerImpl.java:236）中.UndertowDeploymentService $ 1.run（UndertowDeploymentService.java:82）... 6更多引起：java.lang.IllegalArgumentException：无法注册名为'dispatcher'的servlet . 如果有另一个servlet注册在同一名称下，请检查 . org.springframework.util.Assert.notNull（Assert.java:115）org.springframework.web.servlet.support.AbstractDispatcherServletInitializer.registerDispatcherServlet（AbstractDispatcherServletInitializer.java:98）org.springframework.web.servlet.support.AbstractDispatcherServletInitializer位于io.undertow的io.undertow.servlet.core.DeploymentManagerImpl $ 1.call（DeploymentManagerImpl.java:186）org.springframework.web.SpringServletContainerInitializer.onStartup（SpringServletContainerInitializer.java:169）的.onStartup（AbstractDispatcherServletInitializer.java:71） .servlet.core.DeploymentManagerImpl $ 1.call（DeploymentManagerImpl.java:171）at io.undertow.servlet.core.ServletRequestContextThreadSetupAction $ 1.call（ServletRequestContextThreadSetupAction.java:42）at io.undertow.servlet.core.ContextClassLoaderSetupAction $ 1.call（ ContextClassLoaderSetupAction.java:43）在io.undertow.servlet.api.L上的io.undertow.servlet.api.LegacyThreadSetupActionWrapper $ 1.call（LegacyThreadSetupActionWrapper.java:44） egoThreadSetupActionWrapper $ 1.call（LegacyThreadSetupActionWrapper.java:44）at io.undertow.servlet.api.LegacyThreadSetupActionWrapper $ 1.call（LegacyThreadSetupActionWrapper.java:44）at io.undertow.servlet.api.LegacyThreadSetupActionWrapper $ 1.call（LegacyThreadSetupActionWrapper.java:44 ）at io.undertow.servlet.api.LegacyThreadSetupActionWrapper $ 1.call（LegacyThreadSetupActionWrapper.java:44）at io.undertow.servlet.core.DeploymentManagerImpl.deploy（DeploymentManagerImpl.java:234）

The hightlight of the error is that “无法注册名称为'dispatcher'的servlet . 检查是否有另一个以相同名称注册的servlet . 在org.wildfly.extension.undertow.deployment.UndertowDeploymentService $ 1.run（UndertowDeploymentService.java:85）”

请帮我解决这个问题 . 我在日食上使用WildFly-10 .
