網(wǎng)上處理方法一籮筐，下面說說我用過的兩種有效地解決辦法.
1.為程序編寫一個(gè)字符串處理函數(shù)，用一個(gè)靜態(tài)文件保存，在需要處理中文字符的JSP頁(yè)面中包含它，
復(fù)制代碼 代碼如下:
%!
public String codeToString(String str)
{
String s=str;
try
{
byte temp[]=s.getBytes("ISO-8859-1");
s=new String(temp);
return s;
}
catch(Exception e)
{
return s;
}
}
%>
要轉(zhuǎn)換時(shí)只需：coedeToString(request.getParameter(..));就可以了，很好用的。
2.一種普遍適用的方法，加一個(gè)過濾器，之后就可以過上一勞永逸的日子了。
復(fù)制代碼 代碼如下:
package filters;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
public class TomcatFormFilter implements Filter {
/**
* Request.java
* 對(duì) HttpServletRequestWrapper 進(jìn)行擴(kuò)充, 不影響原來的功能并能提供所
有的 HttpServletRequest
* 接口中的功能. 它可以統(tǒng)一的對(duì) Tomcat 默認(rèn)設(shè)置下的中文問題進(jìn)行解決而只
需要用新的 Request 對(duì)象替換頁(yè)面中的
* request 對(duì)象即可.
*/
class Request extends HttpServletRequestWrapper
{
public Request(HttpServletRequest request) {
super(request);
}
/**
* 轉(zhuǎn)換由表單讀取的數(shù)據(jù)的內(nèi)碼.
* 從 ISO 字符轉(zhuǎn)到 GBK.
*/
public String toChi(String input) {
try {
byte[] bytes = input.getBytes("ISO8859-1");
return new String(bytes, "GBK");
}
catch (Exception ex) {
}
return null;
}
/**
* Return the HttpServletRequest holded by this object.
*/
private HttpServletRequest getHttpServletRequest()
{
return (HttpServletRequest)super.getRequest();
}
/**
* 讀取參數(shù) -- 修正了中文問題.
*/
public String getParameter(String name)
{
return
toChi(getHttpServletRequest().getParameter(name));
}
/**
* 讀取參數(shù)列表 - 修正了中文問題.
*/
public String[] getParameterValues(String name)
{
String values[] =
getHttpServletRequest().getParameterValues(name);
if (values != null) {
for (int i = 0; i values.length; i++) {
values[i] = toChi(values[i]);
}
}
return values;
}
}
public void destroy() {
}
public void doFilter(ServletRequest request, ServletResponse
response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpreq = (HttpServletRequest)request;
if(httpreq.getMethod().equals("POST")) {
request.setCharacterEncoding("GBK");
} else {
request = new Request(httpreq);
}
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws
ServletException {
}
}
當(dāng)然要記得改下web.xml
復(fù)制代碼 代碼如下:
filter>
filter-name>TomcatFormFilter/filter-name>
filter-class>filters.TomcatFormFilter/filter-class>
/filter>
filter-mapping>
filter-name>TomcatFormFilter/filter-name>
url-pattern>/*/url-pattern>
/filter-mapping>
上面兩種方法都測(cè)試過了，比較好用，以后發(fā)現(xiàn)新的，會(huì)再更新哦~
