这是我的web.xml文件:

<?xml version = '1.0' encoding = 'GBK'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns  /javaee/web-app_2_5.xsd"
     version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">

</web-app>

Servlet的:

public class OrganizationLoadServlet extends HttpServlet {
    private static Logger log = Logger.getLogger(OrganizationLoadServlet.class);

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

        Organization[] orgs = (Organization[])session.getAttribute(WorklistappConstants.SESS_ATTR_PREFS_ORGANIZATIONS);

        if (orgs == null) {
            orgs = getFilteredOrgs(request);
            session.setAttribute(WorklistappConstants.SESS_ATTR_PREFS_ORGANIZATIONS, orgs);
        }

        log.info("Before: " + response.getCharacterEncoding());//Here I am getting "iso-8859-1"
        StringBuffer sb = new StringBuffer();
        String dislayName = null;
        for (int i = 0; i < orgs.length; i++) {
            Organization org = orgs[i];
            dislayName = org.getOrgDisplayName();

            sb.append("<ITEMS>");
            sb.append("<LABEL><![CDATA[" + dislayName + "]]></LABEL>");
            sb.append("<VALUE><![CDATA[" + org.getOrgId() + "]]></VALUE>");
            sb.append("</ITEMS>");
        }

        response.setContentType("text/xml");
        response.setHeader("Cache-Control", "no-cache");
        response.getWriter().write("<?xml version=\"1.0\" encoding=\"iso-8859-1\"?><ITEM>" + sb.toString() + "</ITEM>");
        log.info("After: " + response.getCharacterEncoding());//Here I am getting "iso-8859-1"

    }

    public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        this.doGet(request, response);
    }

    private Organization[] getFilteredOrgs(HttpServletRequest request) {
    //code
    return orgs;

    }

    private Organization[] filterOrganizationsByUserOrgs(Organization[] orgs, List<Long> userOrgIdList) {
        //code

        return filteredOrgs;
    }

    private List<Long> getUserOrgIdList(String userId) throws Exception {
    //code

        return userOrgIdList;
    }

    private String getUserID(HttpServletRequest request) throws IOException {

    //code
        return wfCtx.getUser();
    }

}

请参阅Servlet类中的注释.如果我将iso-8859-1更改为utf-8,那么我无法访问该应用程序.

为什么会出现这个问题?

试试这个

>添加汉字后,以UTF-8编码保存JSP,而不是将其保存在ISO-8859-1中
>尝试添加此行
<%@ page contentType =“text / html; charset = UTF-8”%>在你的JSP标题

希望能帮助到你.
