作者:”PANDA

这篇文章主要介绍了Springboot内嵌SQLite配置使用详解,本文通过实例代码给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

版本号

MacOS Apple M1 | Jdk17 | Maven 3.8.5 | SpringBoot 2.6.9 | SQLite 3.42.0.0

pom.xml

<dependencies>
    <dependency>
            <groupId>org.xerial</groupId>
            <artifactId>sqlite-jdbc</artifactId>
            <version>3.42.0.0</version>
        </dependency>
        <dependency>
            <groupId>com.github.gwenn</groupId>
            <artifactId>sqlite-dialect</artifactId>
            <version>0.1.4</version>
        </dependency>
</dependencies>

基础配置

application.properties

# data source
spring.datasource.url=jdbc:sqlite:tutorial.db
spring.datasource.driver-class-name=org.sqlite.JDBC
# spring.datasource.journal_mode=WAL
spring.datasource.hikari.maximum-pool-size=1
spring.jpa.properties.hibernate.dialect=org.sqlite.hibernate.dialect.SQLiteDialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

Configuration

import java.util.Properties;
import javax.annotation.Resource;
import javax.sql.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
@Configuration
@EnableJpaRepositories(basePackages = "com.dipeak.diengine.backend.dao")
public class DataSourceConfig {
  @Resource private Environment environment;
  @Bean
  public DataSource dataSource() {
    final DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(environment.getProperty("spring.datasource.driver-class-name"));
    dataSource.setUrl(environment.getProperty("spring.datasource.url"));
    return dataSource;
  }
  @Bean
  public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPackagesToScan(new String[] {"com.dipeak.diengine.backend.model.entity"});
    em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
    em.setJpaProperties(additionalProperties());
    return em;
  }
  final Properties additionalProperties() {
    final Properties hibernateProperties = new Properties();
    if (environment.getProperty("spring.jpa.hibernate.ddl-auto") != null) {
      hibernateProperties.setProperty(
          "hibernate.hbm2ddl.auto", environment.getProperty("spring.jpa.hibernate.ddl-auto"));
    }
    if (environment.getProperty("spring.jpa.properties.hibernate.dialect") != null) {
      hibernateProperties.setProperty(
          "hibernate.dialect", environment.getProperty("spring.jpa.properties.hibernate.dialect"));
    }
    if (environment.getProperty("hibernate.show_sql") != null) {
      hibernateProperties.setProperty(
          "hibernate.show_sql", environment.getProperty("hibernate.show_sql"));
    }
    return hibernateProperties;
  }
}

Entity 定义

@Entity
@Table(name = "users")
public class User {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long id;
  private String name;
}

Repository 定义

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
  @Query("select u from User u where u.id <= ?1")
  Page<User> findMore(Long maxId, Pageable pageable);
  @Modifying
  @Transactional
  @Query("update User u set u.name = ?1 where u.id = ?2")
  int updateById(String name, Long id);
}

Unit Test

public class SqliteTest {
    @Resource private UserRepository userRepository;
    @Test
    public void insert() {
        User user = new User();
        user.setId(3l);
        user.setName("wang da fang");
        userRepository.save(user);
    }
}
