使用jod 3.0之后的一个新问题
@空杯子 你好,想跟你请教个问题:
之前您在这个问题回答过我。http://www.oschina.net/question/143986_87688
之后我就采用了jod3.0 因为我不想频繁的开启和关闭服务 我就把office开启服务放到了Spring容器开启启动和结束时关闭。管理一个openofficemanager 的bean 。
现在有个这样的问题:因为要解决上面这个连接的问题,只需要释放服务就可以了,所以我就做了转化失败重启服务的操作,之后的转化即使是正确的文件格式也是报错。
以下是错误信息:
严重: Servlet.service() for servlet [action] in context with path [/ewfs] threw exception [Request processing failed; nested exception is java.util.concurrent.RejectedExecutionException] with root cause java.util.concurrent.RejectedExecutionException at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:1760) at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:767) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:658) at java.util.concurrent.AbstractExecutorService.submit(AbstractExecutorService.java:78) at org.artofsolving.jodconverter.office.PooledOfficeManager.execute(PooledOfficeManager.java:71) at org.artofsolving.jodconverter.office.ProcessPoolOfficeManager.execute(ProcessPoolOfficeManager.java:78) at org.artofsolving.jodconverter.OfficeDocumentConverter.convert(OfficeDocumentConverter.java:78) at org.artofsolving.jodconverter.OfficeDocumentConverter.convert(OfficeDocumentConverter.java:69) at sl.ewfs.office.commons.DOC2PDFUtil.conventToPdf(DOC2PDFUtil.java:80) at sl.ewfs.office.commons.DOC2PDFUtil.TxtConventToPdf(DOC2PDFUtil.java:109) at sl.ewfs.office.action.FileInfoAction.ConventToSWF(FileInfoAction.java:591) at sl.ewfs.office.action.FileInfoAction.fileUpload(FileInfoAction.java:426) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.springframework.web.bind.annotation.support.HandlerMethodInvoker.invokeHandlerMethod(HandlerMethodInvoker.java:176) at org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.invokeHandlerMethod(AnnotationMethodHandlerAdapter.java:426) at org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.handle(AnnotationMethodHandlerAdapter.java:414) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:790) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:719) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644) at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:560) at javax.servlet.http.HttpServlet.service(HttpServlet.java:641) at javax.servlet.http.HttpServlet.service(HttpServlet.java:722) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:88) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:224) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:169) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:168) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:98) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:927) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:987) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:579) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:309) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619)管理的bean 我是这样写的

<bean id="openOffice" class="sl.ewfs.office.commons.OpenOfficeManager" init-method="init" destroy-method="destroy"> <!-- 转化任务超时时间为5分钟 --> <property name="taskTimeout" value="300000" /> </bean>

大哥 解决了吗,能给个意见吗
我感觉代码没什么问题;
不过“听说”jod不能同时转换多个文件,你看看是不是这个原因引起的啊;
还有,个人建议将转换的方法设计成静态方法,没必要交给Spring管理;

嗯 ,是每次都转化一个,没有这方面的资料。这样太慢了呢,想做成并发转化,同时开几个转化的端口出来试试。嗯,我多试试。谢谢你哈。
