首先需要修改服务器Tomcat的编码，打开config目录下的server.xml文件，在
然后再写个过滤器，就万事OK了！
写一个JAVA类
package com.company.filter;
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;
/**
* 编码过滤器实体类
* @author Administrator
*
*/
public class EncodingFilter implements Filter {
private FilterConfig config;
private String encoding="utf-8";
public void destroy() {
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding(encoding);//过滤请求的编码
chain.doFilter(request, response);//继续过滤
response.setContentType("text/html;charset=utf-8");//过滤响应的编码
}
public void init(FilterConfig config) throws ServletException {
this.config=config;
String s=config.getInitParameter("encoding");//获取初始化参数数，
if(s!=null){
this.encoding=s;
}
}
}
再在项目的web.xml中配置：
