java - 如何使用 Spring 测试框架测试非 Spring 控制器

Question

任何人都可以为我提供一些有关如何执行此操作的指导或代码示例吗？

主页控制器.java

public class HomePageController extends HttpServlet {

    private static final Logger log = Logger.getLogger(HomePageController.class);

    @Override
    public void init(ServletConfig config) throws ServletException {
        super.init(config);
    }

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        processRequest(request, response);
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        processRequest(request, response);
    }

    protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        log.debug("Into the HomePageController...");
        showPage(request, response, HOME_PAGE_URL);
    }

    private void showPage(HttpServletRequest request, HttpServletResponse response, String viewName) throws ServletException, IOException {
        log.debug("Displaying " + viewName + " page now...");
        String url = TEMPLATE_PAGE_URL + "?gotoPage=" + viewName;
        //forward the request to the page
        request.getServletContext().getRequestDispatcher(url).forward(request, response);
    }

}
