spring get方法 中文(UTF

问题：

前端用Get方法进行如下请求：

在浏览器中输入：http://localhost:8080/dmaList/ExportBySQL?sql=&names=分区级别&size=10&currentpage=1

后端方法接收代码如下：

    @RequestMapping(value="/ExportSQL",produces = "text/plain;charset=UTF-8")

    @ResponseBody

    public Boolean  ExportMonitorStationInfoBySQL(HttpServletRequest request,HttpServletResponse response,@RequestParam(value="sql") String sql,@RequestParam(value="size") int size,@RequestParam(value="names") String names,@RequestParam(value="currentpage") int currentPage)

    {

        try {

            names = new String(names.getBytes("ISO-8859-1"),"UTF-8");

        } catch (UnsupportedEncodingException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        int offset=(currentPage-1)*size;

        int totalCount=dmaServcie.getDmaCountByAdvance(sql);

        List<WLCS_DMAExt>data= dmaServcie.getDmaByPageByAdvance(sql, size, offset);

        Page<WLCS_DMAExt> result=new Page<WLCS_DMAExt>(currentPage, size, totalCount, data);

        return dmaServcie.ExportMonitorStationInfo(response, names, data);

    }

结果参数names乱码，如下图所示。

解决办法：

使用names = new String(names.getBytes("ISO-8859-1"),"UTF-8");

上面的代码已经把解决办法写出来了，转换后的结果如下图所示:

PS：

项目中使用了如下方法(在web.xml中添加)解决乱码问题，结果不行：

  <filter>

    <filter-name>encodingFilter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <async-supported>true</async-supported>

    <init-param>

      <param-name>encoding</param-name>

      <param-value>UTF-8</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>encodingFilter</filter-name>

    <url-pattern>/</url-pattern>

  </filter-mapping>

  <filter>
