Java 在tomcat7上的类路径上未检测到Spring WebApplicationInitializer类型

java spring tomcat

Java 在tomcat7上的类路径上未检测到Spring WebApplicationInitializer类型,java,spring,tomcat,war,build.gradle,Java,Spring,Tomcat,War,Build.gradle,我是tomcat的新手。我经营“gradle tomcatRunWar”。此web应用程序可以在本地运行，并调用了WebApplicationInitializer。然后，我用“gradlewar”来获取war文件。我删除了/var/lib/tomcat7/webapps/中的所有内容。我将myproject.war复制到/var/lib/tomcat7/webapps/目录。将其重命名为ROOT.war。重新启动tomcat7。服务器开始运行。但我无法通过我的ip:8080/登录或我的ip:8

我是tomcat的新手。我经营“gradle tomcatRunWar”。此web应用程序可以在本地运行，并调用了WebApplicationInitializer。然后，我用“gradlewar”来获取war文件。我删除了/var/lib/tomcat7/webapps/中的所有内容。我将myproject.war复制到/var/lib/tomcat7/webapps/目录。将其重命名为ROOT.war。重新启动tomcat7。服务器开始运行。但我无法通过我的ip:8080/登录或我的ip:8080/我的项目/登录访问我的网页。错误为“HTTP状态404-/login”。在localhost.log中，有一个信息：“信息：在类路径上未检测到Spring WebApplicationInitializer类型。”。我通过谷歌搜索了这个问题，一些人因为lib版本，jdk版本而有同样的问题。我不知道如何调试

在localhost.log中，有一条信息：信息：在类路径上未检测到Spring WebApplicationInitializer类型

My Application.java是：

    @Configuration
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {
      @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(Application.class);
        }

        public static void main(String[] args) throws Exception {
            SpringApplication.run(Application.class, args);
        }

}
我的WebAppInitializer.java是：

@Configuration
public class WebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext)
            throws ServletException {

        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
        appContext.register(Application.class);
        ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
                "SpringDispatcher", new DispatcherServlet(appContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }
}
更新

我使用web.xml代替WebApplicationInitializer。现在它可以工作了。

问题是关于您的访问目录，您需要验证什么是您的CATALINA_HOME环境变量，日志中清楚显示“目录不存在”

无法从执行位置访问

解决方案： 1.首先，尝试在不使用Gradle的情况下单独启动tomcat。 2.在tomcat中部署任何hello world web应用程序 3.试着一步一步地使用Gradle 4.要了解更多关于Gradle的信息，请查看以下内容：

注意。

显示整个tomcat日志。作为文本，而不是图片，我遇到了同样的问题（我碰巧使用的是Eclipse/Spring/Maven，而不是Gradle）。这里讨论了这个问题以及几种可能的解决方法（除了使用web.xml和punting之外）：我的CATALINA_主页是/usr/share/tomcat7。我的CATALINA_基本id/var/lib/tomcat7可能是一个bug：
