web项目引用html5 video标签实现视频播放的坑

项目框架：SpringMVC

最近项目中用到视频播放，打算采用html5 的video标签实现网页视频播放，考虑到兼容性与样式又采用了jquery的video.js插件，使用过程中视频播放都没问题，但是在视频播放的时候运行容器（jetty、tomcat）都会报IO异常：

tomcat：

jetty：下报的是IO异常下的EofException；

百度了下知道EofException是内部类BlockDataInputStream.的方法peekByte抛出的异常，意思就是到达了文件的末尾，程序却没有正常结束读取文件内容。

结合前台查看视频文件的加载方式（分段流加载），而错误总是出现在刷新页面或者来回点击进度条的时候，所以猜测是客户端关闭导致流的输出未正常结束而导致的错误，问了下架构师说可能跟服务器有关系，暂时无法解决，但是日志老是打出那么一大堆错误也很蛋疼，于是我就改写了框架的总体异常过滤器将异常过滤掉：

public class NdrcGlobalHandlerExceptionResolver extends
DefaultHandlerExceptionResolver {

private static final Logger logger = LoggerFactory.getLogger(NdrcGlobalHandlerExceptionResolver.class);

@Override
protected ModelAndView doResolveException(HttpServletRequest request,
HttpServletResponse response, Object handler, Exception ex) {
if(!(ex instanceof IOException)){
logger.error(ex.getMessage(), ex);}
//错误编码
String errorCode = "";
//错误信息
String errorMsg = ex.getMessage();
//EofException则忽略
if(ex instanceof IOException){
Map<String, Object> model = new HashMap<String, Object>();
model.put("ex", ex);
return new ModelAndView();
}
//判断是否框架异常
if (ex instanceof GenericException) {
GenericException be = (GenericException) ex;
errorCode = be.getErrorCode();
errorMsg = be.getMessage();
}
//Ajax请求处理
if (WebUtils.isAjax(request)) {
try {
response.setContentType("application/json");
response.setStatus(HttpStatus.SC_INTERNAL_SERVER_ERROR);
AjaxResult result = AjaxResult.error(errorCode, errorMsg);
//转成json格式
ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(result);

PrintWriter pw = response.getWriter();
pw.write(json);
pw.close();
} catch (Exception e) {
logger.error(errorMsg, e);
}
return null;
} else {
// 跳转到异常页面
Map<String, Object> model = new HashMap<String, Object>();
model.put("ex", ex);
return new ModelAndView("error", model);
}
}
}

并在spring配置文件里面将处理类重新指定：

<!-- 异常视图处理 -->
<bean id="exceptionResolver"
class="com.icinfo.ndrc.support.NdrcGlobalHandlerExceptionResolver">
<!-- 设置日志输出级别，不定义则默认不输出警告等错误日志信息 -->
<property name="warnLogCategory" value="WARN"></property>
</bean>
