Question

大家好我使用jasperreporter作为报告库，使用spring mvc作为控制器，我把这两个用这个

@Bean
 JasperReportsViewResolver getJasperReportsViewResolver() {
  JasperReportsViewResolver resolver = new JasperReportsViewResolver();
  resolver.setPrefix("classpath:/jasperreports/");
  resolver.setSuffix(".jasper");
  resolver.setReportDataKey("datasource");
  resolver.setViewNames("rpt_*");
  resolver.setViewClass(JasperReportsMultiFormatView.class);
  resolver.setOrder(0);
  return resolver;
}  

@Bean
public InternalResourceViewResolver getInternalResourceViewResolver() {
  InternalResourceViewResolver resolver = new InternalResourceViewResolver();
  resolver.setPrefix("/WEB-INF/views/");
  resolver.setSuffix(".jsp");
  resolver.setOrder(1);
  return resolver;
}
@RequestMapping(value = "helloReport4", method = RequestMethod.GET)
public ModelAndView getRpt4(ModelMap modelMap, ModelAndView modelAndView) {
  modelMap.put("datasource", getWidgets());
  modelMap.put("format", "pdf");
  modelAndView = new ModelAndView("rpt_HelloWorld", modelMap);
  return modelAndView;
}

以上是配置和控制器然后我把编译的xxxx.jasper放到webapp目录的某个地方但是当tomcat运行几个小时，大约十个或更多时，当通过浏览器请求jasper视图时，它会产生错误，如[ java.io.FileNotFoundException：无法加载xxxx.html.jasper的资源 ]，在我的路径中，放一些xxxx.jasper 文件，但我只将记者格式设置为 pdf ，有人可以告诉我它！〜

springmvc格式的jasperreporter视图错过了错误
