关于tomcat乱码问题的解决

关于tomcat乱码问题的解决

(一) 更改 C:\Tomcat\conf\server.xml，指定浏览器的编码格式为“简体中文”：

　　方法是找到 server.xml 中的

<Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" URIEncoding='GBK' />


　　

这时地址栏中就可传递中文了，对于tomcat5.0 不加 URIEncoding='GBK' 是不能传递中文的，有中文传递时只能变成乱码。

(二)如servlet不能正常显示汉字 则加入
public class ThreeParams extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html; charset=gb2312");
...
}
}
作用是把页面的内容定义为中文字集gb2312.

(三)如果从数据库中抽取的数据是乱码需要加过滤器

实现如下：
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.UnavailableException;


public class SetCharacterEncodingFilter implements Filter {


public void destroy() {
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)throws IOException, ServletException {

request.setCharacterEncoding("gb2312");

// 传递控制到下一个过滤器
chain.doFilter(request, response);
}

public void init(FilterConfig filterConfig) throws ServletException {
}
}
配置web.xml
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>SetCharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

(四)字符的转换，如在读取文件内容，数据库内容出现乱码时，可由以下办法解决。


public class toGB2312
{
public toGB2312()
{
//
}
public String Gb2312(String uniC){
String gb2312Str = "";
if(uniC == null){
uniC = "";
}
try{
byte[] tep = uniC.getBytes("ISO8859_1");
gb2312Str = new String(tep,"GB2312");
}
catch(Exception ex){
}
return gb2312Str;
}

public String UniC(String gb2312Str){
String unicoStr = "";
if(gb2312Str == null){
gb2312Str = "";
}
try{
byte[] yte = gb2312Str.getBytes("GB2312");
unicoStr = new String(yte,"ISO8859_1");
}catch(Exception ex){
}
return unicoStr;
}
}
你也可以在直接的转换，首先你将获取的字符串用ISO-8859-1进行编码，然后将这个编码存放到一个字节数组中，然后将这个数组转化成字符串对象就可以了，例如：
String str=request.getParameter(“girl”);
Byte B[]=str.getBytes(“ISO-8859-1”);
Str=new String(B);
通过上述转换的话，提交的任何信息都能正确的显示。

clientAccessCheck: proxy request denied in accel_only mode

Squid Cache: Version 2.5

Looks like the client is trying to use you as a proxy, either directly or indirectly via another proxy..
However, HTTP/1.1 requires HTTP servers to accept such request. Turn "httpd_accel_with_proxy on".
You should also make sure your access control rules is set correcly to only allow access to your servers if you haven't already.. Not the cause to your problem, but may be a cause to other problems later if not done..
