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)

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

EncodingFilter
servlets.EncodingFilter


EncodingFilter
*.do
