Spring Boot Hibernate中的java H2 DB不生成DB架构

Question

我想让我的Spring应用程序自动生成DB模式和表。。。 我读过一些问答；A指向此主题，我已将我的DB URL设置为：

H2DataSource.setUrl("jdbc:h2:mem:tmp.db;INIT=CREATE SCHEMA IF NOT EXISTS GPSTRACKER");

我对我的实体做了如下注释：

@Entity
@Table(name="tblGps", schema= "GPSTRACKER")

但是db模式仍然没有创建

这是我的日志输出。Hibernate正在尝试创建表，但找不到架构

我做错了什么？有什么建议吗

EntityManagerFactory

@Bean
    public EntityManagerFactory entityManagerFactory() {

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);
        vendorAdapter.setShowSql(true);
        vendorAdapter.setDatabasePlatform(MyAppSettings.getDbPlattform());

        HibernateJpaDialect jpd = new HibernateJpaDialect();
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();

        factory.setJpaDialect(jpd);
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan(MyAppSettings.packagesToScan);
        factory.setDataSource(MyDataSource());

        return factory.getObject();
    }

数据源

DriverManagerDataSource H2DataSource = new DriverManagerDataSource();
                H2DataSource.setDriverClassName("org.h2.Driver");
                H2DataSource.setUrl("jdbc:h2:mem:tmp.db;INIT=CREATE SCHEMA IF NOT EXISTS GPSTRACKER");

                H2DataSource.setUsername("sa");
                H2DataSource.setPassword("");

@pvgoddijn我记不清了，现在也找不到代码。但我想我需要返回LocalEntityManagerFactory，而不是EntityManagerFactory。。。或类似的东西。祝你好运也许我能在接下来的几天找到代码

创建数据源时，需要设置hbm2ddl。属性，以便在启动时创建/更新数据库

    Properties properties = new Properties();
    properties.put("hibernate.hbm2ddl.auto", "update");
    H2DataSource.setConnectionProperties(properties);

您还可以在hibernate中设置属性。cfg。xml文件

其他可能的值包括：验证|更新|创建|创建删除

有关此属性和其他属性的其他信息，请访问：http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html#configuration-optional
