No Spring WebApplicationInitializer types detected on classpath on tomcat7
提问by BAE
I am new to tomcat. I run "gradle tomcatRunWar". This web application can run locally and WebApplicationInitializerwas called. Then, I used "gradle war" to get war file. I deleted everything in /var/lib/tomcat7/webapps/. I copied myproject.war to /var/lib/tomcat7/webapps/ directory. Renamed it as ROOT.war. Re-started tomcat7. The server started to run. But I can not access my webpage on my_ip:8080/login OR my_ip:8080/myproject/login. The error is "HTTP Status 404 - /login". In the localhost.log, there is an info: “INFO: No Spring WebApplicationInitializer types detected on classpath”. I searched this problem by Google, some people had the same problems because of the lib version, jdk version. I have no idea how to debug.
我是 tomcat 的新手。我运行“gradle tomcatRunWar”。此 Web 应用程序可以在本地运行，并调用了WebApplicationInitializer。然后，我使用“gradle war”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。但是我无法通过 my_ip:8080/login 或 my_ip:8080/myproject/login 访问我的网页。错误是“HTTP 状态 404 - /login”。在 localhost.log 中，有一个信息：“ INFO: No Spring WebApplicationInitializer types detection on classpath”。我用谷歌搜索了这个问题，因为lib版本，jdk版本，有人遇到了同样的问题。我不知道如何调试。

My WebAppInitializer.java is:

public class WebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext)

ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
"SpringDispatcher", new DispatcherServlet(appContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
UPDATE
更新
I used web.xml instead of WebApplicationInitializer. Now it works.
我使用 web.xml 而不是 WebApplicationInitializer。现在它起作用了。

The problem is about your access directory, you need to verify what is your CATALINA_HOME environment variable, the log is clear "directory don't exists".
问题在于您的访问目录，您需要验证您的 CATALINA_HOME 环境变量是什么，日志明确“目录不存在”。
Can't to access from the execution location.
无法从执行位置访问。
SOLUTION: 1. First, try to start tomcat alone without using Gradle. 2. Deploy any hello world web application in your tomcat 3. Try to use Gradle Step by step 4. To learn more about Gradle look at here: http://examples.javacodegeeks.com/core-java/gradle/gradle-hello-world-tutorial/
解决方案： 1. 首先，尝试不使用Gradle 单独启动tomcat。2. 在您的 tomcat 中部署任何 hello world Web 应用程序 3. 尝试使用 Gradle 一步一步 4. 要了解有关 Gradle 的更多信息，请查看此处：http: //examples.javacodegeeks.com/core-java/gradle/gradle-hello -世界教程/
