Spring RedirectView 传值乱码解决

使用的是spring的注解

public ModelAndView toOtherDO(){

// public static final String Constants.NO_PERVIEW = "您没有权限访问";

return new ModelAndView(new RedirectView("toErrorPage.do?errInfo="+Constants.NO_PERVIEW));
}


要重定向到的.do如下:

@RequestMapping("/toErrorPage.do")
public ModelAndView toErrorPage(String errInfo){

try{
logger.debug("errInfo="+errInfo);

return new ModelAndView("error","error",errInfo);

}catch(Exception ex){
ex.printStackTrace();
return new ModelAndView("error","error","转码错误");
}
}

logger.debug出来的errInfo是乱码.


下面是解决方法:

自定义一个编码过滤器

package com.common.core;

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;
import javax.servlet.http.HttpServlet;

public class EncodingFilter extends HttpServlet implements Filter {

/**
*
*/
private static final long serialVersionUID = 9091617359805368168L;

protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;

public void destroy() {
this.encoding = null;
this.filterConfig = null;
}

public void setEncoding(String encoding) {
this.encoding = encoding;
}

@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub

if (ignore || (request.getCharacterEncoding() == null)) {
String encoding = selectEncoding(request);
if (encoding != null)
request.setCharacterEncoding(encoding);
response.setCharacterEncoding(encoding);
}
chain.doFilter(request, response);
}

@Override
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub

this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");

String value = filterConfig.getInitParameter("ignore");
if (value == null)
this.ignore = true;
else if (value.equalsIgnoreCase("true"))
this.ignore = true;
else
this.ignore = false;
}

//设计编码方式
public String selectEncoding(ServletRequest request) {
return (this.encoding);
}
}


web.xml
