Question

当我从Eclipse启动Tomcat 8.5.28时，才会出现此问题。我无法访问我的webapp。 http://localhost:8080/asteriskManagerV3返回404 HTTP错误： 404 error

这是我的配置：

在server.xml中（来自Tomcat）

<Context docBase="asteriskManagerV3" path="/asteriskManagerV3" reloadable="true" source="org.eclipse.jst.jee.server:asteriskManagerV3"/></Host>

web.xml中的

（来自Tomcat）

 <!-- The mapping for the default servlet -->
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
  <servlet-mapping>
        <servlet-name>MaServlet</servlet-name>
        <url-pattern>/actions</url-pattern>
    </servlet-mapping>

web.xml中的

（来自我的项目）

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
  </welcome-file-list>
  <servlet>
    <description></description>
    <display-name>MaServlet</display-name>
    <servlet-name>MaServlet</servlet-name>
    <servlet-class>MaServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>MaServlet</servlet-name>
    <url-pattern>/actions</url-pattern>
  </servlet-mapping>
</web-app>

正如您在此图片中看到的那样 my app is running at /asteriskManagerV3 (at least I think so)

Anf最后，看着日志，我无法确定我的应用程序的部署位置：
