开源OA开发教程（O2OA）：Ftp文件上传方法使用说明_JAVA_编程开发_程序员俱乐部

FTP上传功能因不是平台自带功能，所以需要进行额外的java开发。当把jar包打包后，需要放入到O2目录：o2server\custom\jars。

重启服务器后生效！

一、自定义包DocumentManager.java

class="cm-s-default">package com.z.custom;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.io.IOUtils;
import org.apache.commons.lang3.StringUtils;
import org.apache.commons.vfs2.FileObject;
import org.apache.commons.vfs2.FileSystemException;
import org.apache.commons.vfs2.FileSystemManager;
import org.apache.commons.vfs2.VFS;
public class DocumentManager {
    private static HttpServletRequest request;
    private static FileSystemManager fsManager = null;
    static {
        try {
            fsManager = VFS.getManager();
        } catch (FileSystemException e) {
            System.out.println(e.getMessage());
        }
    }
    public static byte[] readFileToByte(String filePath, String encoding) throws IOException {
        if (StringUtils.isEmpty(filePath)) {
            throw new IOException("File '" + filePath + "' is empty.");
        }
        FileObject fileObj = null;
        InputStream in = null;
        try {
            fileObj = fsManager.resolveFile(filePath);
            if (fileObj.exists()) {
                if (org.apache.commons.vfs2.FileType.FOLDER.equals(fileObj.getType())) {
                    throw new IOException("File '" + filePath + "' exists but is a directory");
                } else {
                    in = fileObj.getContent().getInputStream();
                    return IOUtils.toByteArray(in);
                }
            } else {
                throw new FileNotFoundException("File '" + filePath + "' does not exist");
            }
        } catch (FileSystemException e) {
            throw new IOException("File '" + filePath + "' resolveFile fail.");
        } finally {
            in.close();
            IOUtils.closeQuietly(in);
            if (fileObj != null) {
                fileObj.close();
            }
        }
    }
    public static void writeByteToFile(String filePath, byte[] fileByte, String encoding) throws IOException {
        if (StringUtils.isEmpty(filePath)) {
            throw new IOException("File '" + filePath + "' is empty.");
        }
        FileObject fileObj = null;
        OutputStream out = null;
        filePath = new String(filePath.getBytes("UTF-8"),"ISO-8859-1");
        try {
            fileObj = fsManager.resolveFile(filePath);
            if (!fileObj.exists()) {
                fileObj.createFile();
            } else {
                if (org.apache.commons.vfs2.FileType.FOLDER.equals(fileObj.getType())) {
                    throw new IOException("Write fail. File '" + filePath + "' exists but is a directory");
                }
            }
            out = fileObj.getContent().getOutputStream();
            IOUtils.write(fileByte, out);
        } catch (FileSystemException e) {
            throw new IOException("File '" + filePath + "' resolveFile fail.");
        } finally {
            out.flush();
            out.close();
            IOUtils.closeQuietly(out);
            if (fileObj != null) {
                fileObj.close();
            }
        }
    }
}

二、服务管理平台创建接口编写上传ftp接口代码

1、打开服务管理平台

2、创建接口写上相关代码

/*
* resources.getEntityManagerContainer() // 实体管理容器.
* resources.getContext() //上下文根.
* resources.getOrganization() //组织访问接口.
* requestText //请求内容.
* request //请求对象.
*/
try{
    var result = {
    }
    //FTP信息配置
    var FTPhost = "172.16.92.23"; //FTP服务器IP
    var FTPport = 21;   //FTP服务器端口
    var FTPuserName = "wwx";    //FTP服务器登录用户名
    var FTPpassword = "wwx";    //FTP服务器登录密码
    var FTPpath = "upload";     //存放文件的目录       
    var filePath = "D:\\测试.docx"; //需上传的文件
    var documentManager = Java.type('com.z.custom.DocumentManager'); //实例化java类
    strpath = "ftp://"+FTPuserName+":"+FTPpassword+"@"+FTPhost+"/"+FTPpath+"/测试.docx";
    //调用方法进行上传
    documentManager.writeByteToFile(strpath, documentManager.readFileToByte(filePath,"utf-8"), "utf-8");
    result.state = "NMT0001";
    result.message = "成功";
}catch(e){
    e.printStackTrace();
    result.state = "NMT0002";
    result.message = "失败";
    result.data = e.name + ": " + e.message
}
//JSON.stringify(result);
this.response.setBody(result,"application/json");
