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);
    }
}
