![]() ![]() Apart from the standard connection properties, it is worth mentioning the dialect property which allows us to specify the name of the SQL dialect for the database. Hibernate has many configuration properties. Jdbc:mysql://localhost:3306/test?serverTimezone=UTC Let's go ahead and define the Person class: = "Person")Īnother essential aspect is to create the Hibernate resource file, typically named, where we'll define configuration information: Hibernate requires that an entity class must be created for each table. In this page you will see all items in database, and you can click on the link Edit and Delete to update and remove items.In this section, we'll see how to use Hibernate to manage a JDBC connection to our database.įirst, we need to add the hibernate-coreMaven dependency: The page will redirect to the list pages, as shown below: For the first time, the list is empty because there isn’t any information contained there yet:Ĭlick on the hyperlink Add New Stuff to begin adding a new stuff:Įnter stuff information (Name, Description, Quantity and Location) and click Save. You can type the following url in the web browser to access the Personal Stuff Management Systems Application: In the pop-up dialog choose Tomcat and then click finish Right click on project -> Run As -> Run On Server Let’s look at the code first:Īfter we have completed the project code we need to deploy and test the application to check that it works. Now, we can implement a Java Servlet that acts as a page controller to handle all requests from the client. ![]() The following is code of the JSP file under the WebContentdirectory in the project:Ĭreate a file StuffForm.jsp in folder jspĬreate a file StuffList.jsp in folder jsp Here’s the source code of the DAOStuff class:Ĭreate folders for css (in which to save all css/style files) and jsp (in which to save all jsp files) in WebContent folder :Ĭreate a page with JSP for displaying all information from the database. We now need to implement a DAO (Data Access Object) class that provides CRUD (Create, Read, Update, Delete) operations for the table stuff in the database. ![]() Create new interface class to implement DAO Interface.Create a datasource properties file in folder resources:.Then we can create a Java class named Stuff.java to model a stuff entity in the database with the following code: Then add the following dependencies to the pom.xml file: In the Maven POM dialog, fill Group ID, Artifact ID and Description as shown below: In Eclipse IDE, click File > New > Other and Maven Project. Let’s get started with the application, following the instructions below step by step:Įxecute the following MySQL script to create a database named “ psmsdb” and a table named ” stuff” (of course, you can named your own database and table): MySQL Community Server and MySQL Workbench (GUI Tool).Eclipse IDE for Java EE Developers (one of the newer versions is recommended).The following tools can be used for the development: Java Servlets and Java Server Pages (JSP).In this article we will create applications for personal records management with the following technologies: Updates the content of the table based on the specified primary key for a record.Ĭreate Application with CRUD Implementation Reads the table records based on the primary key within the input parameter. This is a form view to create a new record in the database ![]() CRUD operations can use forms or an interface view to retrieve and return data from a database. CRUD is an acronym for CREATE, READ, UPDATE and DELETE which are basic functions of persistent storage. ![]()
