struts2图片显示

struts2图片显示即是文件下载

一、配置struts.xml

        struts.xml中配置stream结果类型，并配置contentType、inputName、contentDisposition、bufferSize参数即可

 <action name="readImgAction" class="com.bk.eserver.web.action.ImgAction" method="readImg" >
     <result type="stream">
         <param name="contentType">application/octet-stream</param>
         <param name="inputName">inputStream</param>
          <param name="contentDisposition">attachment;filename=${fileName}</param>
         <param name="bufferSize">4096</param>
     </result>
 </action>

二、ImgAction

 public class ImgAction extends WebSupport {
     private InputStream inputStream;

     /**
      * 读取图片
      *
      * @return
      */
     public String readImg() {
         try {
             inputStream = new FileInputStream(new File("D:\\meinv.jpg"));
         } catch (FileNotFoundException e) {
             e.printStackTrace();
         }
         return SUCCESS;
     }

     public InputStream getInputStream() {
         return inputStream;
     }

     public void setInputStream(InputStream inputStream) {
         this.inputStream = inputStream;
     }

 }

三、要显示图片的JSP

 <img  src="admin/readImgAction.do">

恩，页面上将显示如下：
