Deadly simple, right? As with Spring Data JPA, you don't have to write any DAO code.
SPRING MVC ANNOTATIONS CODE
Protected Customer(String name, String email, String address) You see, this is almost the code we need for the data access layer. Import class Customer = GenerationType.IDENTITY) Code Model ClassCreate the domain class Customer to map with the table customer in the database as following: package Note that the persistence unit name SalesDB will be used in the configuration code.Ĥ.
SPRING MVC ANNOTATIONS DRIVER
Create a new directory named META-INF in the source folder to put the persistence.xml file as follows: And write XML code for the persistence.xml file like this: Īs you can see, we specify database connection properties such as URL, user, password and JDBC driver class. Create JPA Configuration FileSince JPA is used, we need to specify database connection properties in the persistence.xml file instead of file. You can see the complete code of the pom.xml file in the sample project attached along this tutorial.Create two Java packages under the source folder: To let the application work with MySQL database, we need to have the dependecy for MySQL JDBC driver:
We use Hibernate as a provider of JPA, so add the following dependency: To use Spring Data JPA, we need to specify the following dependencies: Annotation based Configuration in spring. Specify the following dependency for the core of Spring framework: The Autowired annotation provides control over where and how autowiring can be done.This annotations can be done on setter method,contructor or property.We will see each in detail with example. Declare properties for the version of Spring and Hibernate frameworks: Artifact Id: CustomerManagerMake sure that the JRE version for the project is Java 8 or newer.Next, open the Maven's project file pom.xml to configure the dependencies for the project. Create Project in EclipseCreate a Dynamic Web Project in Eclipse, and convert it to Maven project: right-click on the project, select Configure > Convert to Maven Project.
You can execute the following MySQL script to create the database schema and table: CREATE DATABASE `sales` The table customer has 4 fields: id, name, email and address: The sample application will manage data in a table named customer which is in the schema named sales. Code Search Customer FeatureLet's start with the database first.
SPRING MVC ANNOTATIONS HOW TO
In this Java Spring tutorial, you will learn how to configure a Spring MVC application to work with Spring Data JPA by developing a sample web application that manages information about customers.By completing this tutorial, you will be able to create a Java web application powered by SpringMVC-Spring Data JPA that looks like this: The software programs and technologies used in this tutorial are: Java 8, Apache Tomcat 9, MySQL Server 5.7, Eclipse IDE 4.7 (Oxygen), Spring framework 5.1, Hibernate framework 5.4, Spring Data JPA 2.1.5 and Servlet 3.1.Here's the table of content:ġ3.
