我们在Tomcat 1.6环境中运行Grails 1.3.7应用程序。几天前,我们的一些Pdf报告开始给我们提供问题。大小约1MB或更小的较小报告可以正常工作,但较大的报告会给我们一个'java.net.SocketException:Broken pipe'异常。
为了生成Pdf报告,我们使用itext-2.1.0。然后,我们使用java.net.URLConnection使用户能够下载生成的文件。代码如下:
// retrives file generated using itext
def thisUrl = new File(session.getServletContext().getRealPath("/reports /${pdffilename}")).toURI().toURL();
def connection = null
def pdfInputStream = null
try {
connection = thisUrl.openConnection() //returns a java.net.UrlConnection
pdfInputStream = connection.inputStream
if (connection && pdfInputStream) {
connection.connectTimeout = 25* 60*1000;
connection.readTimeout = 25* 60*1000
response.setHeader "Content-disposition", "attachment; filename = ${pdffilename}"
response.contentType = 'pdf/pdf'
response.outputStream << pdfInputStream // This line fails for large files
} else {
redirect(action: 'failHandler')
}
} catch (e) {
log.info('Could not report, connection may have terminated')
throw e;
} finally {
response.outputStream.flush()
response.outputStream.close()
}
'response.outputStream&lt;&lt;对于较大的文件大小,pdfInputStream'失败,给出了以下异常:

检查服务器中是否有Load Balancer。这可能会导致您的连接超时
