使用Struts 2和Hibernate在jsp页面中显示Blob（图像）

最终，我为未来的Google员工解决了这一问题：

将此行添加到jsp，

 <img src="<s:url value="YourImageShowAction" />" border="0" width="100" height="100">

这是

ShowImageAction

import java.io.IOException;import java.io.OutputStream;import java.sql.SQLException;import javax.servlet.http.HttpServletResponse;import org.apache.struts2.ServletActionContext;import com.raysep.maxlist.domain.post.image.Image;public class ShowImageAction {  private static byte[] itemImage;  public static void execute() {      try {          Image slika = Image.fetchOne();          HttpServletResponse response =

ServletActionContext.getResponse();
response.reset();
response.setContentType(“multipart/form-data”);

          itemImage = slika.getImage().getBytes(1,(int)

slika.getImage().length());

          OutputStream out = response.getOutputStream();          out.write(itemImage);          out.flush();          out.close();      } catch (SQLException e) {          e.printStackTrace();      } catch (IOException e) {          e.printStackTrace();      }  }  public byte[] getItemImage() {      return itemImage;  }  public void setItemImage(byte[] itemImage) {      this.itemImage = itemImage;  }}
