Fonzie ORM framework in the Java library usage guidelines
The FONZIE ORM framework is a tool for operating object relationship mapping in the Java library.It helps developers to easily map the Java object with the database table to simplify the process of data persistence.This article will introduce the guidelines of the Fonzie ORM framework in the Java class library.
Using the Fonzie ORM framework can make developers focus more on the implementation of business logic without paying too much attention to the details of the database operation.The following will guide you how to use the Fonzie ORM framework in the Java project.
The first step is the dependence of introducing the Fonzie ORM framework in the project.You can add the following dependent configuration to the pom.xml file of the project:
<dependency>
<groupId>com.fonzie</groupId>
<artifactId>fonzie-orm</artifactId>
<version>1.0.0</version>
</dependency>
Next, you need to create a physical class and map it to the database table.Suppose we have a physical class called User, corresponding to the User table in the database, the structure is as follows:
@Entity
@Table(name = "user")
public class User {
@Id
@Column(name = "id")
private Long id;
@Column(name = "username")
private String username;
@Column(name = "password")
private String password;
// omit the getter and setter method
}
You need to configure the database connection information.You can add the following configuration in the project configuration file (such as Application.properties): the following configuration:
properties
fonzie.orm.datasource.url=jdbc:mysql://localhost:3306/mydb
fonzie.orm.datasource.username=root
fonzie.orm.datasource.password=root
fonzie.orm.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
Finally, you can use the Fonzie ORM framework in business logic for database operations.For example, you can create a new User object through the following code and save it into the database:
User user = new User();
user.setUsername("test");
user.setPassword("123456");
FonzieEntityManager entityManager = FonzieEntityManagerFactory.createEntityManager();
entityManager.getTransaction().begin();
entityManager.persist(user);
entityManager.getTransaction().commit();
entityManager.close();
Through the above steps, you can use the Fonzie ORM framework in the Java library for an object relationship mapping operation.I hope this article will help you.
