本人小白，用maven调用servlet出现500异常，求大神告诉我怎么解决？

使用maven调用servlet报错如下：
严重: Allocate exception for servlet myServlet
java.lang.ClassNotFoundException: com.web.servlet.myServlet

pom.xml中配置：

<dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>servlet-api</artifactId>
      <version>2.5</version>
      <scope>provided</scope>
    </dependency>

    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jsp-api</artifactId>
      <version>2.0</version>
      <scope>provided</scope>
    </dependency>
  </dependencies>

web.xml中配置：

    <servlet>
        <servlet-name>myServlet</servlet-name>
        <servlet-class>com.web.servlet.myServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>myServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

servlet中代码：

public class myServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws javax.servlet.ServletException, IOException {
        this.doGet(request,response);
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws javax.servlet.ServletException, IOException {
        request.getRequestDispatcher("/hello.jsp").forward(request,response);
    }

找到错误原因了：
因为没有把java文件放在main目录下导致找不到Servlet文件
