Hibernate Jakarta Data Spring Integration

数据访问层解决方案 - Hibernate Data Repository 与 Spring 框架的集成

Hibernate Data Repositories特性

• 安全 编译时检查，避免运行时错误
• HQL - 比JPQL更简洁强大，Record投影无需new关键字
• 方法参数派生查询 - 比基于方法名的查询更简洁
• 动态查询DSL - 使用Hibernate 7.x的全新Restriction DSL实现动态查询
• 无状态 - 没有级联操作，没有懒加载，没有只读事务，同步操作，没有事务后写

🚀 快速开始

1. 添加依赖,添加注解处理器

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

<dependencies>
<dependency>
    <groupId>com.github.luckygc</groupId>
    <artifactId>jakarta-data-spring</artifactId>
    <version>1.1.3</version>

</dependencies>

            </compilerArgs>

            <annotationProcessorPaths>
                <path>

                    <artifactId>lombok</artifactId>
                    <version>${lombok.version}</version>

                    <groupId>org.hibernate.orm</groupId>
                    <artifactId>hibernate-processor</artifactId>
                    <version>${hibernate.version}</version>
                </path>
            </annotationProcessorPaths>
        </configuration>
    </plugin>

</plugins>
</build>

2. 配置类

@Configuration
@EnableDataRepositories(basePackages = "com.example.repository")
public class HibernateDataConfiguration {

    @Bean
    public SessionFactory sessionFactory(DataSource dataSource) {
        SessionFactoryBean sessionFactoryBean = new SessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource);
        sessionFactoryBean.setPackagesToScan("com.example.entity");
        return sessionFactoryBean.getObject();
    }
}
