Struts2 Hibernate displays multiple images on a JSP page

Recently need to traverse a JSP page above a number of pictures, usually do more is a string integer and other types of traversal, the picture is binary and the original commonly used types are very different.

Bbfseal.java

public class Bbfseal {

Private Blob content;

Private String ID;

private String name;

Private Bbfuseruser;

Private Blob imageseal;

Public Bbfseal ()

{

}

Public Bbfseal (Blob imageseal, String ID) {

Super ();

This.imageseal = Imageseal;

This.id = ID;

}

Public String GetName () {

return name;

}

public void SetName (String name) {

THIS.name = name;

}

public void SetContent (Blob content) {

this.content = content;

}

Public Blob getcontent () {

return content;

}

public void SetId (String id) {

This.id = ID;

}

Public String getId () {

return ID;

}

public void SetUser (Bbfuser user) {

This.user = user;

}

Public Bbfuser GetUser () {

return user;

}

Public Blob Getimageseal () {

return imageseal;

}

public void Setimageseal (Blob imageseal) {

This.imageseal = Imageseal;

}

}

The main code in the action

/**

* Find all the stamps according to the user ID

*/

Public String showseallist () {

HttpServletRequest request = Servletactioncontext.getrequest ();

Bbfuser user = (Bbfuser) request.getsession (). getattribute ("user");

String uid = User.getid ();

This.bbfseals = This.manage.listSeals (UID);

return "Toseallist";

}

/**

* Display photo Information

*/

Public String Showseal () {

Bbfseal seal = manage.loadseal (ID);

Instantiates a byte array stream, storing the photo bytes in the table

InputStream = new Bytearrayinputstream (blobtobinaryutils

. Blobtobinary (Seal.getimageseal ()));

Return "Success";

}
