java将文件上载到服务器端会在控制台上生成错误“拒绝访问”

11 月，2 周 Questions & Answers 1257

我的服务器端是一个JSP应用程序，它托管在AppacheTomcat7（eclipse中的插件）上。我的客户方是：-

if(("GET").equalsIgnoreCase(request.getMethod())&&("Create Reimbursement").equalsIgnoreCase(request.getParameter("Create Reimbursement"))){ 
//crresult = lmktweb.createReimbursement(Integer.parseInt(request.getParameter("ID")), request.getParameter("EmpdID"), request.getParameter("DateCreated"), request.getParameter("Amount"),request.getParameter("Vendor"),request.getParameter("picpath"));
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.80.125:8080/UploadFileServerSide/UploadHandler.jsp");
MultipartEntity entity = new MultipartEntity();
System.out.println(request.getParameter("fname"));
if(request.getParameter("fname")!=""){
    File file = new File(request.getParameter("fname"));
    entity.addPart("data", new FileBody(file));
    httppost.setEntity(entity);    
    HttpResponse resp = httpclient.execute(httppost);
}

我的服务器端是：-

try {
                        String itemName = item.getName();
                        String fpath = "";
                        //item.
                        File root=File.listRoots()[0];
                        String extPath;
                        if(crdate!=""){
                            extPath = rei.HandlePathWithDate(crdate,getServletContext().getRealPath("images"));
                            fpath = extPath+"\\"+ppath;
                            fpath = extPath.replaceAll("/", "\\");
                        }   
                        else{

                            extPath= getServletContext().getRealPath("/");
                            fpath = extPath.concat("\\"+itemName);                              
                            fpath = extPath.replaceAll("/", "\\");                          

                        }
                        System.out.println("Saving as: " +fpath);
                        File f = new File(fpath);

                        f.setWritable(true);
                        f.setReadable(true);
                        item.write(f);

                    } catch (Exception e) {
                        e.printStackTrace();
                        response.setHeader("Error", e.getMessage());                            
                    }

但在给定路径上写入文件时会产生以下错误：-

Saving as: D:\Z-Main\Projects\Android Projects.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\UploadFileServerSide\ java.io.FileNotFoundException: D:\Z-Main\Projects\Android Projects.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\UploadFileServerSide (Access is denied) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.(Unknown Source) at java.io.FileOutputStream.(Unknown Source) at org.apache.commons.fileupload.disk.DiskFileItem.write(DiskFileItem.java:426) at org.apache.jsp.UploadHandler_jsp._jspService(UploadHandler_jsp.java:154) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:722) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:432) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334) 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.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:225) 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:999) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:565) at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1812) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

问题在哪里。我目前正在使用Tomcat Eclipse插件，这个错误出现在控制台上。我在安卓应用程序中调用相同的代码，它运行良好。请提供有用的详细信息。我试着编辑catalina。位于eclipse服务器插件文件夹中的策略文件，并添加了以下行：-

grant codeBase " file:${catalina.base}/webapps/UploadFileServerSide/-" {
  ermission java.io.FilePermission "${tomcat.home}/-","read,write"; };

并从eclipse重新启动服务器，期望得到不同的结果，但到目前为止运气不佳。我在哪里迷路了

有 Java 编程相关的问题?
