运行项目时，请求的资源不可用

Question

在运行我的jsf项目时需要帮助。 web.xml是：

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"

    </welcome-file-list>

    <!-- JSF mapping -->

您必须使用这些依赖项：

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>javax.servlet.jsp-api</artifactId>
        <version>2.3.1</version>
        <scope>provided</scope>
    </dependency>

使用以下web.xml配置

  <servlet>
    <servlet-name>myServlet</servlet-name>
    <servlet-
 class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ApplicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>encoding-filter</filter-name>
    <filter-
 class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
   <filter-name>encoding-filter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
