ftp实现图片上传，文件也类似

本来用得是easyui得控件 点击按钮实现选择图片得 ，但是老板非得要双击图片框实现上传代码。。。。做个简单得记录

前端代码：

首先，<form>表单要加上 enctype="multipart/form-data"  才能实现上传文件

然后这是

<div data-options="prompt:'图片展示'" id="img" style="text-algin:center;height:150px;width:205px;vertical-align:middle;border:1px solid #95B8E7;border-radius:5px" >
    <img id="urlImg" width="205px" height="150px" ondblclick="fileSelect();">
</div>

下面是双击事件，  下面得是图片预览 ，上篇随笔介绍过了

function fileSelect() {
            document.getElementById("fileToUpload").click(); 
        }
        
        $("#fileToUpload").change(function(){
            $("#urlImg").attr("src",URL.createObjectURL($(this)[0].files[0]));
        });

接下来的后端代码

数据库加了个url的字段，用来存储图片名称，名称是随机生成的

Action层：

//添加
    public void insertSpecificMCodeInformation() {
            
            SpecificMCodeInformation specificMCodeInformation = new SpecificMCodeInformation();
            
            //mCodeInformation.setTypeID(parentID+typeID);
            //specificMCodeInformation.setTypeID(typeID);
            specificMCodeInformation.setParentID(parentID);
            specificMCodeInformation.setIllustration(illustration);
            specificMCodeInformation.setTypeName(typeName);
            specificMCodeInformation.setEntryUnit(entryUnit);
            specificMCodeInformation.setAlias(alias);
            specificMCodeInformation.setAlias1(alias1);
            specificMCodeInformation.setAlias2(alias2);
            specificMCodeInformation.setEntryPerson(entryPerson);
            specificMCodeInformation.setEntryDate(DateStringUtil.DateToStr(new Date()));
            specificMCodeInformation.setNorms(norms);
            specificMCodeInformation.setModel(model);
            specificMCodeInformation.setUrl(url);
            if( fileToUpload != null ) {
                // 统一调用一个上传方法，方便后期维护
                String img = specificMCodeInformationService.saveContImg(fileToUpload, fileToUploadFileName, typeID);
                specificMCodeInformation.setUrl(img);
                System.out.println("IMGGGGGGGGGGGGGGGGG"+specificMCodeInformation.getUrl());
            }
            
            specificMCodeInformationService.insertSpecificMCodeInformation(specificMCodeInformation);
            writeJson(specificMCodeInformation);
        }
    

DAO层：

    public int insertSpecificMCodeInformation(@Param("specificMCodeInformation")SpecificMCodeInformation specificMCodeInformation);

Service层：

    public void insertSpecificMCodeInformation(SpecificMCodeInformation specificMCodeInformation);
    public String saveContImg( File upload, String uploadFileName, String typeID );

实现层：

@Override
    public void insertSpecificMCodeInformation(SpecificMCodeInformation specificMCodeInformation) {
        // TODO Auto-generated method stub
        try {
            System.out.println(createTypeID(specificMCodeInformation.getParentID()));
            System.out.println("alias:"+specificMCodeInformation.getAlias());
            System.out.println("norms:"+specificMCodeInformation.getNorms());
            System.out.println("model:"+specificMCodeInformation.getModel());
            System.out.println("entryUnit:"+specificMCodeInformation.getEntryUnit());
            specificMCodeInformation.setTypeID(createTypeID(specificMCodeInformation.getParentID()));
            System.out.println("typeID"+specificMCodeInformation.getTypeID());
            System.out.println("url"+specificMCodeInformation.getUrl());
            specificInformationMapper.insertSpecificMCodeInformation(specificMCodeInformation);
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
        
    }

这个用来生成文件名：

@Override
    public String saveContImg(File fileToUpload, String fileToUploadFileName, String typeID) {
        String saveFileName = "";
        FTPUtil f = new FTPUtil();
        try {
            String ip = ReadProperty.getValue( "common.properties", "ftp.url" );
            String username = ReadProperty.getValue( "common.properties", "ftp.username" );
            String password = ReadProperty.getValue( "common.properties", "ftp.password" );
            String port = ReadProperty.getValue( "common.properties", "ftp.port" );
            int iPort = Integer.valueOf( port );
            f.initClient( ip, iPort, username, password );
            InputStream in = new FileInputStream( fileToUpload );
            System.out.println("INNNN"+in);
            String path = ReadProperty.getValue( "common.properties", "ftp.materiel" ) + typeID + "\\";
            System.out.println("PATHHHHH"+path);
            saveFileName = GUID.getGUID() + fileToUploadFileName.substring( fileToUploadFileName.lastIndexOf( "." ) );
            System.out.println("FILENameEEEEE"+saveFileName);
            f.upLoadFile( path, saveFileName, in );
        } catch( Exception e ) {
            e.printStackTrace();
        } finally {
            f.closeConnection();
        }
        return saveFileName;
    
    }

实体层不写了
