9/26/2023 0 Comments Tutorial crud java netbeans mysqlThe listBook object will be passed from a servlet which we will create later.On running, this page looks something like this: As you can see, on this page we have two hyperlinks at the top menu for creating a new book ( Add New Book) and showing all books ( List All Books). In this JSP page, we use JSTL to display records of the table book from database. The following is code of the BookList.jsppage under the WebContentdirectory in the project: Writing Book Listing JSP PageNext, create a JSP page for displaying all books from the database. Delete: deleteBook(Book) - this removes an existing row in the database based on the primary key value (ID).įor detailed instructions on CRUD operations with JDBC, see JDBC Tutorial: SQL Insert, Select, Update, and Delete Examples.Update: updateBook(Book)- this updates an existing row in the database.Read: listAllBooks() - this retrieves all rows and getBook(id)- returns a specific row based on the primary key value (ID).Create: insertBook(Book)- this inserts a new row into the table book.And the following methods are for CRUD operations: Public Book(int id, String title, String author, float price) As you can see, the JDBC connection information is injected to this class via its constructor. * This is a model class represents a book entity Writing Model ClassNext, create a Java class named Book.java to model a book entity in the database with the following code: package As you can see, the dependencies here are for Servlet, JSP, JSTL and MySQL connector Java (a JDBC driver for MySQL).And remember to create a Java package for the project, here we use the package name. Then add the following dependencies to the pom.xml file: Then convert this project to a Maven project by right click on the project, select Configure > Convert to Maven Project, as shown below: You need to enter information to create Maven POM file, such as group ID, artifact ID, etc. Name the project as Bookstore: Remember to choose Target runtime as Apache Tomcat v8.0 and Dynamic web module version as 3.1 (this is the Java servlet version).Click Finish. Creating Eclipse Project with MavenIn Eclipse IDE, click File > New > Dynamic Web Project to create a new Java dynamic web project. ) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=latin1The table book has structure like this: You can use either MySQL Command Line Client or MySQL Workbench tool to create the database.Ģ. `book_id` int(11) NOT NULL AUTO_INCREMENT, Execute the following MySQL script to create a database named Bookstore and a table named Book: CREATE DATABASE 'Bookstore' Creating MySQL DatabaseFor simplicity, we have only one table. We use Eclipse IDE with Maven to develop the project. Java Servlets and Java Server Pages (JSP).The web application in this tutorial uses the JSF. The application looks something like this: You will learn to how to build this application using the following technologies: The combination of the four have become known as CRUD (an albeit non-flattering but easy to remember acronym). In this Java tutorial, we’re going to help you understand the process of coding a basic Java web application that manages a collection of books with the basic feature: list, insert, update, delete (or CURD operations - Create, Update, Read and Delete).
