java GET POST提交乱码问题

1.整体思想，编码方式统一(采用utf-8)
2页面显示中文乱码

<%page pageEncoding="utf-8"%>

３传递中文参数乱码

修改server.xml(解决get方式)

<Connector port="8080" protocol="HTTP/1.1" maxThreads="150" connectionTimeout="20000"

  redirectPort="8443" URIEncoding="UTF-8"/>

编写过滤器(Filter)(解决post方式)

package servlets;   

import java.io.IOException;  

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 EncodingFilter implements Filter {  
  public void init(FilterConfig config) throws ServletException {  
  }  

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

  public void destroy() {  
  }  
}
 

在web.xml注册

<filter>  
  <filter-name>EncodingFilter</filter-name>  
  <filter-class>servlets.EncodingFilter</filter-class>  
  </filter>  
  <filter-mapping>  
  <filter-name>EncodingFilter</filter-name>  
  <url-pattern>*.do</url-pattern>  
  </filter-mapping>
