【Java Web】【1】传统form表单上传file文件，struts后台接受

1.搭建简单的struts2框架

 --->src的下struts.xml

 --->根目录下struts.xml

--->jar包导入

--->web.xml配置

  TestForm
  
    
    struts2  
    org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter  
    
	
		struts2
		/*
	
  
  
    index.html
    index.htm
    index.jsp
    default.html
    default.htm
    default.jsp
  

2.前台页面：Hellow.jsp

3.action配置

package com.test.action;

import java.io.File;

import com.opensymphony.xwork2.ActionSupport;

public class formAction extends ActionSupport {

	private static final long serialVersionUID = -2757669937510150666L;
	
	private File file;

	public File getFile() {
		return file;
	}

	public void setFile(File file) {
		this.file = file;
	}

	private String fileContentType;
	
	private String fileFileName;
	
	public String getFileContentType() {
		return fileContentType;
	}

	public void setFileContentType(String fileContentType) {
		this.fileContentType = fileContentType;
	}

	public String getFileFileName() {
		return fileFileName;
	}

	public void setFileFileName(String fileFileName) {
		this.fileFileName = fileFileName;
	}

	private String number;

	public String getNumber() {
		return number;
	}

	public void setNumber(String number) {
		this.number = number;
	}
	
	public void testNumber(){
		System.out.println(number.toString());
	}
	
	public void testFile(){
		System.out.println(this.getFileFileName());
		System.out.println(file.getName());
	}
	

}

4.项目目录

PS:表单为file类型的时候，上传到后端，必须要有3个参数，参数在

标签下中的name值一致，对应在action中是private File ？；private  String  ?ContentType ; private String ?FileName ;
