Java中怎么對(duì)接遠(yuǎn)程文件

Java中怎么對(duì)接遠(yuǎn)程文件，相信很多沒有經(jīng)驗(yàn)的人對(duì)此束手無策，為此本文總結(jié)了問題出現(xiàn)的原因和解決方法，通過這篇文章希望你能解決這個(gè)問題。

1、配置文件：copyRemoteFile.properties

#  src/dao.properties    #      這里保存的都是鍵值對(duì)信息    #  interface name(no packgage) = implementation class  # 注意：    #A：【路徑符號(hào)】【必須】是【/】【如：D:/home/publish】    #B：【鍵key=值value】對(duì)【后面】【絕不允許有空格】【如：REMOTE_HOST_IP=172.77.9.77】   # REMOTE_HOST_IP  遠(yuǎn)程機(jī)器IP    # LOGIN_ACCOUNT   遠(yuǎn)程機(jī)器登錄名    # LOGIN_PASSWORD  遠(yuǎn)程機(jī)器登錄密碼    # SHARE_DOC_NAME  遠(yuǎn)程機(jī)器共享文件夾名（設(shè)置共享后必須授予讀寫權(quán)限）   # sourcePath      本地路徑    # targetPath      目標(biāo)路徑（真實(shí)路徑=共享文件夾路徑+目標(biāo)路徑）   REMOTE_HOST_IP=172.77.9.77   LOGIN_ACCOUNT=77   LOGIN_PASSWORD=77   SHARE_DOC_NAME=vfs_home    sourcePath=D:/home/publish   targetPath=publish

2、導(dǎo)入jar包：jcifs-1.3.16.jar

3、讀取配置文件中key對(duì)應(yīng)的value類：RemoteConfigUtil.java

package com.remote;       import java.io.IOException;   import java.util.Properties;       /**    * 讀取配置文件中key對(duì)應(yīng)的value    * @author JunjieQin    */ public class RemoteConfigUtil {       private String REMOTE_HOST_IP;       private String LOGIN_ACCOUNT;       private String LOGIN_PASSWORD;       private String SHARE_DOC_NAME;       private String sourcePath;       private String targetPath;           //無參構(gòu)造方法       public RemoteConfigUtil() {           try {               // 讀取配置文件               Properties prop = new Properties();               prop.load(this.getClass().getClassLoader().getResourceAsStream("copyRemoteFile.properties"));               // 根據(jù) key 獲取 value               REMOTE_HOST_IP = prop.getProperty("REMOTE_HOST_IP");               LOGIN_ACCOUNT = prop.getProperty("LOGIN_ACCOUNT");               LOGIN_PASSWORD = prop.getProperty("LOGIN_PASSWORD");               SHARE_DOC_NAME = prop.getProperty("SHARE_DOC_NAME");               sourcePath = prop.getProperty("sourcePath");               targetPath = prop.getProperty("targetPath");           } catch (IOException e) {               e.printStackTrace();           }       }       public String getLOGIN_ACCOUNT() {           return LOGIN_ACCOUNT;       }           public void setLOGIN_ACCOUNT(String login_account) {           LOGIN_ACCOUNT = login_account;       }           public String getLOGIN_PASSWORD() {           return LOGIN_PASSWORD;       }           public void setLOGIN_PASSWORD(String login_password) {           LOGIN_PASSWORD = login_password;       }           public String getREMOTE_HOST_IP() {           return REMOTE_HOST_IP;       }           public void setREMOTE_HOST_IP(String remote_host_ip) {           REMOTE_HOST_IP = remote_host_ip;       }           public String getSHARE_DOC_NAME() {           return SHARE_DOC_NAME;       }           public void setSHARE_DOC_NAME(String share_doc_name) {           SHARE_DOC_NAME = share_doc_name;       }           public String getSourcePath() {           return sourcePath;       }           public void setSourcePath(String sourcePath) {           this.sourcePath = sourcePath;       }           public String getTargetPath() {           return targetPath;       }           public void setTargetPath(String targetPath) {           this.targetPath = targetPath;       }   }

4、操作遠(yuǎn)程共享文件夾類： RemoteFileUtil.java
