1.下载reportng源码

     git clone  https://github.com/dwdyer/reportng.git

2.修改AbstractReporter.java

把原来的注释掉，改成如下的   

  package org.uncommons.reportng;

     ...

     import java.io.OutputStream;

     ...

     protected void generateFile(File file,

                                String templateName,

                                VelocityContext context) throws Exception

    {

        //Writer writer = new BufferedWriter(new FileWriter(file));

        //encoding to utf-8

        OutputStream out = new FileOutputStream(file);

        Writer writer = new BufferedWriter(new OutputStreamWriter(out,"utf-8"));

        try

        {

            Velocity.mergeTemplate(classpathPrefix + templateName,

                                   ENCODING,

                                   context,

                                   writer);

            writer.flush();

        }

        finally

        {

            writer.close();

        }

    }

3、把整个reportng文件导入到eclipse中

4、在eclipse中导出为jar文件（取名为reportng-1.1.4）

5、找到原来的maven仓库下的reportng1.1.4，替换掉

6、重新基于套件运行，查看网页报告，无中文乱码了
