Step 1: Establish a database Create Table test_img (ID Number (4), Name Varchar (20), IMG Long Raw);
Step 2:
Add picture </ title> </ head> <body> Add picture <br> <form method = "post" action = "insertnews.jsp"> Image ID: < Input name = "id" size = "10"> <br> Select Image: <input type = "file" name = "image"> <br> <input type = "Submit" Value = "Upload" Name = "SUBMIT "size =" 25 "> <input type =" reset "value =" Clear "name =" clear "size =" 25 "> <br> </ form> </ body> </ html></p>
<p>Step 3: Insert the database (InsertImg.jsp)</p>
<p><% @ page language = "java"%> <% @ page contentType = "text / html; charSet = GB2312"%> <% @ page import = "java.util. *"%> <% @ page import = " Java.sql. * "%> <% @ Page Import =" java.text. * "%> <% @ page import =" java.io. * "%></p>
<p><% Class.forname ("Oracle.jdbc.driver.OracleDriver"); string url = "JDBC: Oracle: Thin: @lubin: 1521: b2bdb"; connection con = DRIVERMANAGER.GETCONNECTION (URL, "Demo", "Demo ");</p>
<p>// Insert the database string SQL = "INSERT INTO TEST_IMG VALUES (?,?,?)"; // Get the Value ID String ID = Request.getParameter ("ID"); // Get image of Image String KK = Request. GetParameter ("Image"); // Convert to File File FileName = New File (KK);</p>
<p>// read the length of the file and convert to a long-type long L1 = filename.length (); int L2 = (int) L1;</p>
<p>// Assign fileinputstream fis = new fileinputstream (filename) with stream format; fileInputStream (filename);</p></div><div class="text-center mt-3 text-grey">
