common-upload文件上传封装

jopen 5年前

为了更方便的让每次上传进行使用,对common-upload进行了一个简单的封装。

package com.onsafe.util.upload;    /**   * 文件屬性bean   * @author lushuifa   */  public class FileBean {   private String fileName;// 文件名   private String fileContentType;// 上传文件的数据类型   private long fileSize;// 文件的大小;单位byte   private String extName;// 文件扩展名的大小   private String fieldName;   private String filePath;   private String fileNote;//文件说明   private String newFileName;//新文件名     public String getFileName() {    return fileName;   }     public void setFileName(String fileName) {    this.fileName = fileName;   }     public String getFileContentType() {    return fileContentType;   }     public void setFileContentType(String fileContentType) {    this.fileContentType = fileContentType;   }     public long getFileSize() {    return fileSize;   }     public void setFileSize(long fileSize) {    this.fileSize = fileSize;   }     public String getExtName() {    return extName;   }     public void setExtName(String extName) {    this.extName = extName;   }     public String getFilePath() {    return filePath;   }     public void setFilePath(String filePath) {    this.filePath = filePath;   }     public String getFieldName() {    return fieldName;   }     public void setFieldName(String fieldName) {    this.fieldName = fieldName;   }     public String getFileNote() {    return fileNote;   }     public void setFileNote(String fileNote) {    this.fileNote = fileNote;   }     public String getNewFileName() {    return newFileName;   }     public void setNewFileName(String newFileName) {    this.newFileName = newFileName;   }  }
