URL中文乱码

日日日!
又出乱码了
我操
①修改Tomcat---->conf----->server.xml文件，在修改端口的标签后面加一行代码，如下：
Xml代码 复制代码

   1. <Connector port="8080" protocol="HTTP/1.1"  
   2.               connectionTimeout="20000"  
   3.               redirectPort="8443"  URIEncoding="UTF-8"/> 

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"  URIEncoding="UTF-8"/>


②编写过滤器Filter
Java代码 复制代码

   1.      
   2. import java.io.IOException; 
   3.  
   4. import javax.servlet.Filter; 
   5. import javax.servlet.FilterChain; 
   6. import javax.servlet.FilterConfig; 
   7. import javax.servlet.ServletException; 
   8. import javax.servlet.ServletRequest; 
   9. import javax.servlet.ServletResponse; 
  10.  
  11. public class CharacterEncodingFilter implements Filter ...{ 
  12.  
  13.     @Override 
  14.     public void destroy() ...{ 
  15.     } 
  16.  
  17.     @Override 
  18.     public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,ServletException   { 
  19.     request.setCharacterEncoding("utf-8"); 
  20.     chain.doFilter(request, response); 
  21.     } 
  22.  
  23.     @Override 
  24.     public void init(FilterConfig arg0) throws ServletException ...{ 
  25.     } 
  26.  
  27. } 

   
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;

public class CharacterEncodingFilter implements Filter ...{

    @Override
    public void destroy() ...{
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,ServletException   {
    request.setCharacterEncoding("utf-8");
    chain.doFilter(request, response);
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException ...{
    }

}



  利用过滤器，把requst传递的中文参数都设成“UTF-8”编码。

③修改web.xml文件

    打开项目里的web.xml文件，在前面加上如下代码：
Xml代码 复制代码

   1.     
   2. <filter> 
   3. <filter-name>characterEncoding</filter-name> 
   4. <filter-class>com.v512.example.CharacterEncodingFilter</filter-class> 
   5. </filter> 
   6. <filter-mapping> 
   7. <filter-name>characterEncoding</filter-name> 
   8. <url-pattern>/*</url-pattern> 
   9. </filter-mapping> 

   
<filter>
<filter-name>characterEncoding</filter-name>
<filter-class>com.v512.example.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>characterEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>


注意其过滤的URL为“/*”，表示当前的request请求。为了使设置生效，重起tomcat。
