当我试图在我的 JSP 页面中显示中文字符时，它会显示垃圾字符。
我做错了什么？
我已在顶部的 JSP 中包含以下行，即使现在，问题也没有得到解决：

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"

小服务程序：
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。如果我更改iso-8859-1为utf-8，那么我将无法访问该应用程序。
为什么会出现这个问题？
