从这个问题开始。

How to servlet println(); tag <c:forEach>

我试图通过javaservlet中的println来使代言模式成为可能。

我已经可以修复它，但是我发现所有泰语节目都像???????。我尝试通过使用来修复 response.setContentType（“ text / html; charset = UTF-8”）和response.setCharacterEncoding（“ UTF-8”）或者我尝试使用jsp进行修复。但这不起作用。

这是我的引导程序模式代码

您可以看到我的员工引导程序表上没有泰语的问题，但是引导模式有泰语的问题。

Answer 1

我发现此问题来自我的Servlet代码中的 PrintWriter pw = response.getWriter（）; 。但是我不知道为什么。

viewServlet.java

@WebServlet(urlPatterns = { "/view" })
public class viewSerlvet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    public viewSerlvet() {
        super();
    }

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        HttpSession session = request.getSession();

        // Check User has logged on
            userAccount loginedUser = myUtils.getLoginedUser(session);

        // Not logged in
        if (loginedUser == null) {
            // Redirect to login page.
            response.sendRedirect(request.getContextPath() + "/login");
            return;
        }
        // Store info to the request attribute before forwarding.
        request.setAttribute("user", loginedUser);

        String errorString = null;

        Connection conn = myUtils.getStoredConnection(request);
        String typeQuerystring = request.getParameter("type");
        String definitionIDQuerystring = request.getParameter("definitionid");
        PrintWriter pw = response.getWriter();
        if (definitionIDQuerystring == null) {
            switch (typeQuerystring)
            {
            case "employees":
                List<provinces> provincesList = null;
                try {
                    provincesList = dbUtils.queryProvinces(conn);
                } catch (SQLException e) {
                    e.printStackTrace();
                    errorString = e.getMessage();
                }
                request.setAttribute("provincesList", provincesList);
                break;
            case "customers":
                break;
            case "suppilers":
                break;
            case "stocklocation":
                break;
            case "categories":
                break;
            case "items":
                break;
            case "profile":
                break;
            default:
                response.getWriter().print("Invalid Parameter!");
                }
            }
            else {
                switch (typeQuerystring)
                {
                case "employees":
                    break;
                case "customers":
                    break;
                case "suppilers":
                    break;
                case "stocklocation":
                    break;
                case "categories":
                    break;
                case "items":
                    break;
                case "profile":
                    break;
                default:
                    response.getWriter().print("Invalid Parameter!");
                }
            }

        // Store info in request attribute, before forward to views
        request.setAttribute("errorString", errorString);

        // Forward to /WEB-INF/views/productListView.jsp
        RequestDispatcher dispatcher = request.getServletContext()
                .getRequestDispatcher("/WEB-INF/views/viewView.jsp");
        //        .getRequestDispatcher("/WEB-INF/test.jsp");
        dispatcher.forward(request, response);
    }

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

}
