day3——关于<s:if/>和文件上传

一个小的注意点

<s:if test=‘#backyear==#yearatd‘>selected="selected"</s:if> 

<s:if test=‘%{#backmonth==-1}‘>selected="selected"</s:if>

 

文件上传(struts2)

jsp:

  <form name="myform" method="post" action="employeesAdd" enctype="multipart/form-data">

  <p><span>上传头像:</span><input type="file" class="txtinput" name="upload" /></p>

Action:

  //上传文件 
  private File upload;

  //上传文件名
  private String uploadFileName;
  //上传文件类型
  private String uploadContentType;

 

  //....getter、setter

  

  public String AddEmployee(){

    //项目路径
    String root = ServletActionContext.getServletContext().getRealPath("/");

    //文件存放目录
    String filepath = root+File.separatorChar+"upload";
  try {

    //复制文件到服务器中
    FileUtils.copyFile(upload, new File(filepath,uploadFileName));

    //访问文件的路径(File.separatorChar相当于"/")
    String imgurl = "upload"+File.separatorChar+uploadFileName;


    employee.setEpicture(imgurl);
    
  } catch (IOException e) {
    // TODO Auto-generated catch block
  e.printStackTrace();
  }
  employeesService.addEmployee(employee);
  return SUCCESS;
  }
