Struts中文問(wèn)題怎么解決
碰到struts中文問(wèn)題時(shí),JSP頁(yè)面上仍然顯示的是亂碼,下面方法在windows的weblogic8下,和unix的weblogic8下均正確顯示漢字。一起來(lái)看看吧!
以下是代碼內(nèi)容:
首先是JSP頁(yè)面的內(nèi)容,最簡(jiǎn)化的一個(gè)form
TestItem English :
TestItem Chinese :
注意,頁(yè)面的字符集一定要定義成gb2312,否則顯示不了正確的漢字了,代碼上半部的logic:iterate 標(biāo)簽是 action 處理完畢后,返回給頁(yè)面顯示的。至于form提交的部分,由struts機(jī)制去做了,我只把 testitem_config 這個(gè) action 的原代碼給出,大家就看明白了:
public class TestItemConfigAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)throws Exception {
TestItemConfigForm pcForm = (TestItemConfigForm)form;
String[] entryIndexArray = pcForm.getEntrypro();
String testPartKey;
ArrayList testPartOptionsEn = new ArrayList();
ArrayList testPartOptionsCn = new ArrayList();
ServletContext context = getServlet()。getServletContext();
String file = context.getRealPath(“/WEB-INF/classes/resource/TestItem.properties”);
PropertiesFileOperate pOperate = new PropertiesFileOperate(file);
Properties property = pOperate.getProperties();
int testpartnum = Integer.parseInt(property.getProperty(“test.item.num”));
if(pcForm.getOperateFlag() != null && !“”。equals(pcForm.getOperateFlag())) {
if(Integer.parseInt(pcForm.getOperateFlag()) == 1 &&
pcForm.getTestItemEn() != null && !“”。equals(pcForm.getTestItemEn())){
String addKeyEn = “test.item.en.” + (testpartnum + 1);
String addKeyCn = “test.item.cn.” + (testpartnum + 1);
String addValueEn = pcForm.getTestItemEn()。trim();
String addValueCn = pcForm.getTestItemCn()。trim();
String addValueCnWirite = new String(addValueCn.getBytes(“ISO-8859-1”));
pOperate.modifyProperties(“test.item.num”, (testpartnum + 1) + “”);
pOperate.addProperties(addKeyEn, addValueEn);
pOperate.addProperties(addKeyCn, addValueCnWirite);
pOperate.saveFile();
pOperate = null;
}
if(Integer.parseInt(pcForm.getOperateFlag()) == 2 &&
pcForm.getTestItemEn() != null && !“”。equals(pcForm.getTestItemEn())){
int entryIndex = Integer.parseInt(pcForm.getTestItemIndex()。trim());
String addKeyEn = “test.item.en.” + entryIndex;
String addKeyCn = “test.item.cn.” + entryIndex;
String addValueEn = pcForm.getTestItemEn()。trim();
String addValueCn = pcForm.getTestItemCn()。trim();
String addValueCnWirite = new String(addValueCn.getBytes(“ISO-8859-1”));
pOperate.modifyProperties(addKeyEn, addValueEn);
pOperate.modifyProperties(addKeyCn, addValueCnWirite);
pOperate.saveFile();
pOperate = null;
}
if(Integer.parseInt(pcForm.getOperateFlag()) == 3){
for(int i = 0; i 《 entryIndexArray.length; i++){
String indexEntry = (entryIndexArray[i]。substring(1, entryIndexArray[i]。indexOf(“,”)))。trim();
String addKeyEn = “test.item.en.” + indexEntry;
String addKeyCn = “test.item.cn.” + indexEntry;
pOperate.modifyProperties(addKeyEn, “”);
pOperate.modifyProperties(addKeyCn, “”);
}
pOperate.saveFile();
pOperate = null;
}
}
PropertiesFileOperate pOperateShow = new PropertiesFileOperate(file);
Properties propertyShow = pOperateShow.getProperties();
int testpartNumber = Integer.parseInt(propertyShow.getProperty(“test.item.num”));
ArrayList array = new ArrayList();
for(int i = 1; i 《= testpartNumber; i++){
ArrayList arr = new ArrayList();
testPartKey = “test.item.en.”+i;
if (propertyShow.getProperty(testPartKey) != null &&
!“”。equals(propertyShow.getProperty(testPartKey))){
arr.add(i+“”);
testPartOptionsEn.add(propertyShow.getProperty(testPartKey));
arr.add(propertyShow.getProperty(testPartKey));
testPartKey = “test.item.cn.”+i;
testPartOptionsCn.add(new String(propertyShow.getProperty(testPartKey)。getBytes(),“gb2312”));
arr.add(propertyShow.getProperty(testPartKey));
array.add(arr);
}
}
request.setAttribute(“box”,array);
pcForm.reset(mapping, request);
return mapping.findForward(“testitemone”);
}
}
這個(gè) action 并不復(fù)雜, 首先它定義了一個(gè) properties 文件 TestItem.properties,在web服務(wù)器下的/WEB-INF/classes/resource/下面,用來(lái)記錄頁(yè)面上輸入的內(nèi)容,由于 String addValueCnWirite = new String(addValueCn.getBytes(“ISO-8859-1”)) 這個(gè)語(yǔ)句進(jìn)行了字符轉(zhuǎn)換,所以 properties 文件中記錄的內(nèi)容大概都是這樣子的:
test.item.cn.29=\u7F1D\u9699\u5F02\u5E38
如果把程序改成記錄到數(shù)據(jù)庫(kù)中,也應(yīng)該是這個(gè)樣子,屬于Unicode編碼吧。
而當(dāng)要把記錄的內(nèi)容輸出到客戶(hù)端時(shí)候,new String(propertyShow.getProperty(testPartKey)。getBytes(),“gb2312”)) 這個(gè)語(yǔ)句又把Unicode編碼轉(zhuǎn)換成了GB2312,所以要求JSP頁(yè)面charset=gb2312,這樣在windows 和 unix兩個(gè)系統(tǒng)下都可以正常顯示中文了,絕對(duì)沒(méi)有問(wèn)題。
