Question

我的项目在Jetty 6上运行得很好，但是在Jetty 7.5+上（我检查了7.5,8.1和9.0）我在Jetty启动时遇到No such servlet异常（项目部署，我猜）。

的web.xml

<servlet-mapping>
    <servlet-name>TestServlet</servlet-name>
    <url-pattern>/TestServlet</url-pattern>
</servlet-mapping>
<servlet>
    <servlet-name>TestServlet</servlet-name>
    <servlet-class>myproject.servlets.TestServlet</servlet-class>
</servlet>

TestServlet.java

public class TestServlet extends HttpServlet {
    private static final long serialVersionUID = 3992344538270432732L;

    @Override
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<body>");
        out.println("<h1>Hello Servlet Get</h1>");
        out.println("</body>");
        out.println("</html>");
    }   
}

撤销web.xml中的顺序解决了问题：

<servlet>
    <servlet-name>TestServlet</servlet-name>
    <servlet-class>myproject.servlets.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>TestServlet</servlet-name>
    <url-pattern>/TestServlet</url-pattern>
</servlet-mapping>

我猜Jetty的早期版本对servlet声明的顺序并不那么严格。

Jetty 6 - ＆gt; Jetty 7.5+给出了“没有这样的servlet”的例外
