具体实施方式
如图1所示，是本发明多点同步存储的文件下载异常处理系统10较佳实施例的架构图。在本实施例中，所述的文件下载异常处理系统10安装并运行于应用服务器1中，该应用服务器1通过网络4连接有至少一台终端设备2和多台文件服务器3，包括第一文件服务器3a和第二文件服务器3b。所述的终端设备2包括，但不仅限于，个人计算机、笔记本电脑、个人数字处理装置（PDA）以及移动通信装置。该终端设备2将用户输入的文件下载请求通过网络4发送到应用服务器1请求从文件服务器3下载用户所需的文件，每一台文件服务器3存储有多种文件资料可供终端设备2下载。
在本实施例中，所述的应用服务器1还包括存储设备11、处理器12以及显示设备13。其中，存储设备11存储有文件存储配置表，其包括文件名称、文件服务器3的编号信息、以及文件存在状态信息。参考图3所示，是一种文件存储配置表的示意图。在本实施例中，假设某一文件的文件名称为“34ced40f2b614a1SZ06”，其同步存储在四个不同地区的文件服务器3中。例如，编号“KS”表示放置在昆山的文件服务器3，编号“SZ”表示放置在深圳的文件服务器3，编号“TW”表示放置在台北的文件服务器3，以及编号“US”表示放置在美国的文件服务器3。其中，文件存在状态“0”表示用户所需的文件没有存在文件服务器3中，文件存在状态“1”表示用户所需的文件存在文件服务器3中。
在本实施例中，所述的文件下载异常处理系统10包括第一下载模块101、第二下载模块102以及异常处理模块103。本发明所称之模块是指一种能够被应用服务器1的处理器12所执行并且能够完成固定功能的一系列计算机程序指令段，其存储于应用服务器1的存储设备11中。
所述的第一下载模块101用于从终端设备2接收用户输入的文件下载请求，该文件下载请求包括终端设备2的IP地址以及文件名称等信息。该第一下载模块101还用于根据终端设备2的IP地址查找与该终端设备2最近的第一文件服务器3a，根据文件名称从该第一文件服务器3a中下载用户所需的文件，以及判断终端设备2是否从第一文件服务器3a成功下载到用户所需的文件。在本实施例中，第一下载模块101通过检查存储在第一文件服务器3a中文件的完整性来判断终端设备2是否从第一文件服务器3a成功下载到文件。当终端设备2从第一文件服务器3a成功下载到用户所需的文件时，第一下载模块101将该文件上传到终端设备2中。
所述的第二下载模块102用于当终端设备2从第一文件服务器3a中没有成功下载到用户所需的文件时，从文件存储配置表中查找存储有该文件的所有远端的文件服务器3。在本实施例中，第二下载模块102根据文件存储配置表中的文件存在状态信息来查找存储有该文件的远端文件服务器3。参考图3所示的文件存储配置表，若文件存在状态为“1”，则表明编号为“KS”和编号为“TW”的远端文件服务器3存在用户所需的文件。若文件存在状态为“0”，则表明编号为“SZ”和编号为“US”的远端文件服务器3不存在用户所需的文件。
所述的第二下载模块102还用于选择其中之一个远端文件服务器3作为下载该文件的第二文件服务器3b，根据文件名称从该第二文件服务器3b中下载用户所需的文件，以及判断终端设备2是否从第二文件服务器3b成功下载到用户所需的文件。在本实施例中，第二下载模块102首先将最初保存有该文件的远端文件服务器3作为第二文件服务器3b。如果最初保存有用户所需文件的远端文件服务器中的文件已损坏，则通过服务轮询方式来选择其它远端文件服务器3作为第二文件服务器3b。第二下载模块102通过检查存储在第二文件服务器3b中文件的完整性来判断终端设备2是否从第二文件服务器3b成功下载到文件。当终端设备2从第二文件服务器3b成功下载到用户所需的文件时，第二下载模块102将该文件上传到终端设备2中。
所述的异常处理模块103用于当终端设备2从第二文件服务器3b成功下载到用户所需的文件时，将第二文件服务器3b中的文件同步存储到第一文件服务器3a中，以便自动修复第一文件服务器3a中的错误文件。该异常处理模块103还用于当终端设备2从第一文件服务器3a或第二文件服务器3b没有成功下载到用户所需的文件时，记录文件下载失败信息并将该文件下载失败信息显示在显示设备13上，提供给管理员分析文件下载失败的原因。
如图2所示，是本发明多点同步存储的文件下载异常处理方法较佳实施例的流程图。在本实施例中，本发明所述的方法能够当终端设备2从近端的文件服务器3下载文件失败后，根据文件存储配置表和服务轮询方式来选择远端的文件服务器3请求下载用户所需的文件，并且可以实现各文件服务器3中错误文件的自动修复功能。
步骤S21，第一下载模块101从终端设备2接收用户输入的文件下载请求，该文件下载请求包括终端设备2的IP地址以及文件名称等信息。步骤S22，第一下载模块101根据终端设备2的IP地址查找与该终端设备2最近的第一文件服务器3a。本实施例中，第一下载模块101通过终端设备2的IP地址与每一个文件服务器3的IP地址来确定最近的第一文件服务器3a。
步骤S23，第一下载模块101根据文件名称从第一文件服务器3a中下载用户所需的文件。步骤S24，第一下载模块101判断终端设备2是否从第一文件服务器3a成功下载到用户所需的文件。若从第一文件服务器3a没有成功下载到用户所需的文件，则执行步骤S25；若终端设备2从第一文件服务器3a成功下载到用户所需的文件，第一下载模块101则将下载到的文件上传到终端设备2中，并流程结束。
步骤S25，第二下载模块102从文件存储配置表中查找存储有用户所需文件的远端的所有文件服务器3。在本实施例中，第二下载模块102根据文件存储配置表中的文件存在状态信息来查找存储有文件的远端文件服务器3。参考图3所示的文件存储配置表，第二下载模块102找出文件存在状态为“1”的远端文件服务器3，例如，编号为“KS”和编号为“TW”的两台远端文件服务器3。
步骤S26，第二下载模块102选择其中之一个远端文件服务器3作为下载该文件的第二文件服务器3b。在本实施例中，第二下载模块102首先将最初上传了该文件的远端文件服务器3作为第二文件服务器3b。如果最初保存有用户所需文件的远端文件服务器中的文件已损坏，则通过服务轮询方式来选择其它远端文件服务器3作为第二文件服务器3b。
步骤S27，第二下载模块102根据文件名称从第二文件服务器3b中下载用户所需的文件。步骤S28，第二下载模块102判断终端设备2是否从第二文件服务器3b成功下载到用户所需的文件。若终端设备2从第二文件服务器3b成功下载到用户所需的文件，则流程执行步骤S29；若从第二文件服务器3b没有成功下载到用户所需的文件，则流程执行步骤S30。
步骤S29，异常处理模块103将第二文件服务器3b中的文件同步存储到第一文件服务器3a中，以便自动修复第一文件服务器3a中的错误文件。当终端设备2从第一文件服务器3a或第二文件服务器3b没有成功下载到用户所需的文件时，步骤S30，异常处理模块103记录文件下载失败信息并将该文件下载失败信息显示在显示设备13上，提供给管理员分析文件下载失败的原因，而后流程返回到S26继续查找下一个远程文件服务器3。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照以上较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换都不应脱离本发明技术方案的精神和范围。
