我已经编写了 servlet。我想测试我的 servlet 类的功能，所以我为我的 servlet 编写了一个测试用例。但是它抛出了以下异常。

com.meterware.httpunit.HttpException: Error on HTTP request: 405 Method Not Allowed [http://localhost:8090/getPrintSettings]

这是我的 Servlet 类：

public class GetPrintSettings extends HttpServlet {

private Logger log;
DB db;
Connection connection;


public void init() throws ServletException { //initialise servlet
    log = Logger.getRootLogger();
    db = new DB();
    connection = db.connect();
    super.init();
}

public void destroy() {  //destroy servlet
    try {
        connection.close();
    } 
    catch (SQLException e) {
        log.error("AddAddress: SQL Exception: "+e.getMessage());
        e.printStackTrace();
    }
    super.destroy();
}


protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {

    int userType = Integer.parseInt(request.getParameter("user"));
    response.setContentType("application/json");        
    PrintWriter out = response.getWriter();

    //Get print settings from JavaClient
    String json = getPrintSettings();

    if(json == null) {
        out.print("{success:false, msg:'Could not send request. Please try again'}");
        out.close();
        return;
    }

    //Send the reply to the web client
    out.print(json);
    out.close();
}

}

这是我的servelt测试用例

  public class GetPrintSettingsTest extends TestCase {

       public static void main( String args[] ) {

    junit.textui.TestRunner.run(GetPrintSettingsTest.class );
   }

public void testGetForm() throws Exception {
    WebConversation web = new WebConversation();
    WebRequest  request = new GetMethodWebRequest("http://localhost:8090/getPrintSettings" );
    WebResponse response = web.getResponse(request);
    request.setParameter("user", "1");
    response = web.getResponse( request );

}

}

我用过httpunit1.7请帮帮我...

提前致谢 ：）

这是因为您已经实施doPost()并访问了GET.

它就在堆栈跟踪的第一行：“405 Method not allowed”。您正在尝试GET从仅实现/允许的 servlet POST。

您可以在您的 servlet 中使用@Override该方法，然后doGet(...)简单地将其转发给该doPost(...)方法 - 然后它就可以工作了。

干杯，
