如何使用Spring Boot/MySQL/Hibernat重新啓動數據庫

我使用Spring Boot，Hibernate，Spring Security工具創建了一個小型Web應用程序，現在我想在瀏覽器中測試它。我猜想一切都很好，但有一個我自己無法解決的小問題。我希望我的DataBase在與populatorDB.sql斷開/連接後自動填充它，以不再次創建/刪除我的數據。這意味着，當我在數據庫中添加/刪除新數據時，在瀏覽器中進行測試時，我將它們放在數據庫中，而不是斷開/連接，並且在數據庫中沒有新數據，只有使用populatorDB.sql的我的標準集。如何使用Spring Boot/MySQL/Hibernat重新啓動數據庫

PopulatorDB.sql

DELETE FROM lardi.user_roles; 
DELETE FROM lardi.contacts; 
DELETE FROM lardi.users; 

INSERT INTO lardi.users 
(login,password,full_name) VALUES 
    ('Bill', '112233', 'user'), 
    ('John', '112233', 'user'), 
    ('Mark', '112233', 'user'); 

INSERT INTO lardi.user_roles 
(role,user_id) VALUES 
    ('ROLE_USER',1), 
    ('ROLE_USER',2), 
    ('ROLE_USER',3); 

INSERT INTO lardi.contacts 
(first_name, last_name, patronymic, mobile_phone_number, home_phone_number, address, email, user_id) VALUES 
    ('Ivan','Ivanov','Ivanovych','+380(66)1234567','','USA','[email protected]', 1), 
    ('Petro','Petrov','Petrovych','+380(66)9876543','+380(44)1122334','USA','[email protected]', 1), 
    ('Sydor','Sydorov','Sydorovych','+380(99)1234567','','USA','[email protected]', 1),

DB配置：

@Configuration 
@EnableTransactionManagement 
public class JPAConfig { 

    @Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
     LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean(); 
     em.setDataSource(dataSource()); 
     em.setPackagesToScan("com.model"); 

     JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
     em.setJpaVendorAdapter(vendorAdapter); 
     em.setJpaProperties(additionalProperties()); 

     return em; 
    } 

    private Properties additionalProperties() { 
     Properties properties = new Properties(); 
     properties.setProperty("hibernate.hbm2ddl.auto", "update"); 
     properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect"); 
     return properties; 
    } 

    @Bean 
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf){ 
     JpaTransactionManager transactionManager = new JpaTransactionManager(); 
     transactionManager.setEntityManagerFactory(emf); 

     return transactionManager; 
    } 

    @Bean 
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){ 
     return new PersistenceExceptionTranslationPostProcessor(); 
    } 

    @Bean 
    public DataSource dataSource(){ 
     DriverManagerDataSource dataSource = new DriverManagerDataSource(); 
     dataSource.setDriverClassName("com.mysql.jdbc.Driver"); 
     dataSource.setUrl("jdbc:mysql://localhost:3306/lardi?useSSL=false"); 
     dataSource.setUsername("root"); 
     dataSource.setPassword("2940063"); 
     return dataSource; 
    } 

    @Bean(name = "messageSource") 
    public ReloadableResourceBundleMessageSource messageSource(){ 
     ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource(); 
     messageSource.setBasename("classpath:validation"); 
     messageSource.setDefaultEncoding("UTF-8"); 
     return messageSource; 
    } 

    @Bean 
    public DataSourceInitializer dataSourceInitializer(DataSource dataSource){ 
     DataSourceInitializer dataSourceInitializer = new DataSourceInitializer(); 
     dataSourceInitializer.setDataSource(dataSource); 
     ResourceDatabasePopulator databasePopulator = new ResourceDatabasePopulator(); 
     databasePopulator.addScript(new ClassPathResource("populatorDB.sql")); 
     dataSourceInitializer.setDatabasePopulator(databasePopulator); 
     dataSourceInitializer.setEnabled(true); 
     return dataSourceInitializer; 
    } 

    @Bean 
    public static PropertyPlaceholderConfigurer placeHolderConfigurer(){ 
     final PropertyPlaceholderConfigurer props = new PropertyPlaceholderConfigurer(); 
     props.setSystemPropertiesMode(PropertyPlaceholderConfigurer.SYSTEM_PROPERTIES_MODE_OVERRIDE); 
     return props; 
    } 
}

在此先感謝。

您可以將schema.sql和data.sql放入src/main/resources中，並使用默認的JDBC Initializer。

但我在Spring Boot應用程序中沒有'profile（「populatedb」）''。我想在連接之前每次在populatorDB.sql的幫助下自動重啓數據庫。 –

通過連接/斷開你的意思是當用戶登錄和註銷？ –

不，我的意思是在Tomcat中運行應用程序。 –

去掉「更新」屬性，並與

properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");

的hibernate.ddl的自動屬性將創建表進行更換（根據你申報的實體註釋爲@Entity），當應用程序結束時，它將放棄它。
