关于JSP 、 Servlet中文乱码问题， 方法差不多试完了 还是不行- -！

Question

JSP页面1：

list=(List)request.getAttribute("operatorlist"); %>

用户名	密码	等级	操作
			修改用户   删除用户
	添加用户

xxxxxxxxxxxxxxx xxxxxxxxxxxxxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxx
GetOneUserServlet:
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
//response.setCharacterEncoding("utf-8");
OperatorService operatorService=new OperatorService();
System.out.println(request.getParameter("name"));
Operator operator=operatorService.findOne(request.getParameter("name"));
//request.getSession().putValue("updateoperator", operator);
//request.getSession().setAttribute("updateoperator", operator);
if (operator==null) {
System.out.println("operator==null");
}else {
System.out.println("XXXXXXXXXXXXXXXXXXXXXXXXXXX");
}
request.setAttribute("updateoperator", operator);
request.getRequestDispatcher("updateOperator.jsp").forward(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

doGet(request, response);

}如果修改的是JSP页面1中name为中文的记录在这里面的到的是乱码
xxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxx
JSP页面2：

用  户名：
密    码：
	取消

xxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
这个页面有时也会出现乱码- -！

Answer 1

1. JSP 页面需要包含编码只定:
   <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
   如果是html页面, 需要添加metadate:
   

2. 确保文件保存的格式是UTF-8 编码:
   Eclipse 右键属性能看到

下来时GET和POST提交:
1. GET 提交需要配置tomcat/config/server.xml中的connector:
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"/>

1. POST 提交: 需要添加一个Encoding的Filter: [code="java"]

public class EncodingFilter implements Filter {

protected String encoding = "UTF-8";


public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {        

    request.setCharacterEncoding(encoding);
    response.setCharacterEncoding(encoding);

    chain.doFilter(request, response);    
}

public void init(FilterConfig filterConfig) throws ServletException {       
    this.encoding = filterConfig.getInitParameter("encoding");   
}

public void destroy() {
    encoding = null;
}

}
[/code]

Web.xml配置:

[code="xml"]

SetCharacterEncoding
cn.com.dayang.common.web.EncodingFilter

encoding
UTF-8



SetCharacterEncoding
*

[/code]

关于Eclipse输出乱码:
Win系统可能存在这个问题, 检查一下eclipse的console输出是不是采用的GBK编码.
