Question

我正在尝试在springboot和springdata应用程序中设置SQL语句的休眠记录。

我在application.properties文件中设置以下属性：

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type=TRACE

但是不知何故它们没有被拾起，也没有SQL日志出现。也尝试过设置spring.jpa.show-sql属性，但似乎不起作用。

Answer 1

使用记录器就足够了

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE

或者，使用spring.jpa属性，您可以像这样使用它们：

spring.jpa.show-sql = true

另外，为了美化或漂亮地打印SQL，我们可以添加：

spring.jpa.properties.hibernate.format_sql=true

Answer 2

在声明实体管理器bean的地方，添加以下属性。

spring.jpa.show-sql = true
spring.jpa.properties.hibernate.format_sql=true

或在Java批注中

@Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPackagesToScan(HIBERNATE_ENTITIES);
        log.info("Created entity manager successfully");
        JpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();

        //Properties to show SQL format of tables on deploy
        Properties jpaProperties = new Properties();
        jpaProperties.put("hibernate.show_sql", true); // Mark as true to log hibernate queries
        jpaProperties.put("hibernate.format_sql", true); // Mark as true to log hibernate queries
        entityManagerFactoryBean.setJpaProperties(jpaProperties);

        entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        return entityManagerFactoryBean;
    }

编辑：由于您没有使用实体管理器，因此可以直接在配置中执行

    private SessionFactory createSessionFactory(String options) {
      Configuration configuration = new Configuration();
      configuration.setProperty("spring.jpa.properties.hibernate.format_sql", "true");
      configuration.setProperty("hibernate.show_sql", "true");


      StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
          .applySettings(configuration.getProperties());
      SessionFactory sessionFactory = `enter code here`configuration.buildSessionFactory(builder.build());
      return sessionFactory;
    }```

启用带有Spring数据的休眠日志记录？
