碰到struts中文问题时,JSP页面上仍然显示的是乱码,下面方法在windows的weblogic8下,和unix的weblogic8下均正确显示汉字。一起来看看吧!
以下是代码内容:
首先是JSP页面的内容,最简化的一个form
TestItem English :
TestItem Chinese :
注意,页面的字符集一定要定义成gb2312,否则显示不了正确的汉字了,代码上半部的logic:iterate 标签是 action 处理完毕后,返回给页面显示的。至于form提交的部分,由struts机制去做了,我只把 testitem_config 这个 action 的原代码给出,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”);
}
}
这个 action 并不复杂, 首先它定义了一个 properties 文件 TestItem.properties,在web服务器下的/WEB-INF/classes/resource/下面,用来记录页面上输入的内容,由于 String addValueCnWirite = new String(addValueCn.getBytes(“ISO-8859-1”)) 这个语句进行了字符转换,所以 properties 文件中记录的内容大概都是这样子的:
test.item.cn.29=\u7F1D\u9699\u5F02\u5E38
如果把程序改成记录到数据库中,也应该是这个样子,属于Unicode编码吧。
而当要把记录的内容输出到客户端时候,new String(propertyShow.getProperty(testPartKey)。getBytes(),“gb2312”)) 这个语句又把Unicode编码转换成了GB2312,所以要求JSP页面charset=gb2312,这样在windows 和 unix两个系统下都可以正常显示中文了,绝对没有问题。
