Primefaces 解决上传中文乱码问题

在使用primefaces的组件p:fileUpload进行文件上传的时候，如果上传文件名是中文的，上传到服务器看到的文件名就会使乱码，具体解决办法如下：

1、写一个过滤类：

package com.li;

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 CharacterEncodingFilter implements Filter{

    public void destroy() {
       
    }

 public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);
    }

 public void init(FilterConfig filterConfig) throws ServletException {    
    }
}

 

2、在web.xml中配置过滤器：

<!--解决上传乱码问题-->
    <filter>
        <filter-name>Character Encoding Filter</filter-name>
        <filter-class>com.li.CharacterEncodingFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>Character Encoding Filter</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>
   
    <filter>
        <filter-name>PrimeFaces FileUpload Filter</filter-name>
        <filter-class>
   org.primefaces.webapp.filter.FileUploadFilter
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>PrimeFaces FileUpload Filter</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>

 

注：这里需要注意顺序问题。
