Tomcat JSP to access the mysql database:
1. Install the Tomcat and MySqlshuu to download mysql-connector-java.zip, then decompress two files, I download my mysql-connection-java-5.0.0-beta, so two files are mysql-connector-java -5.0.0-beta-bin.jar and mysql-connector-java-5.0.0-beta-bin-g.jar;
2. Copy mysql-connector-java-5.0.0-beta-bin.jar to the Apache-Tomcat / Common / Lib directory, restart Tomcat;
3, write a JSP file, such as Test.jsp:
<% @ Page Import = "java.io. *"%> <% @ page import = "java.util. *"%> <% @ page import = "java.sql. *"%> <% @ page contenttype = "text / html; charSet = GB2312"%>
dbjsp.jsp </ title> </ head> <body> <% connection con; statement stmt; resultset rs;</p>
<p>Class.Forname ("com.mysql.jdbc.driver"); //class.forname ("org.gjt.mm.mysql.driver "). NewInstance ();</p>
<p>DriverManager.registerDriver (new com.mysql.jdbc.Driver ()); String dbUrl = "jdbc: mysql: // localhost:? 3306 / BookDB userUnicode = true & characterEncoding = GB2312"; String dbUser = "user"; String dbPwd = " 123456 "; con = java.sql.driverManager.getConnection (DBURL, DBUSER, DBPWD); stmt = con.createstatement (); rs = stmt.executeQuery (" Select ID, Name, Title, Price from Books "); OUT. Println ("<Table Border Width = 400>); while (rs.next ()) {string col1 = rs.getstring (1); string col2 = rs.getstring (" name "); string col3 = rs.getstring (3); string col4 = rs.getstring (4);</p>
<p>Out.println ("<TD>" COL1 "</ TD> <TD>" COL2 "</ TD> <TD>" COL3 "</ TD> <TD>" COL4 "</ td> </ tr>");} out.println ("</ Table>"); rs.close (); stmt.close () ;con.close ();%> </ body> </ html></p>
<p>4, establish myApp in the apache-tomcat / webapps / directory, store the JSP file in myApp directory; access LocalHost: 8080 / myapp / test.jsp, information display, OK.</p></div><div class="text-center mt-3 text-grey">
