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; } } [2].上传工具类
