java传参乱码，总结

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>
