我正在尝试使用 Spring Boot 构建一个简单的 Web 应用程序。当我重新启动应用程序时,所有数据库表都会重新创建。我尝试将 hibernate.hbm2ddl.auto
设置为 update
或 validate
但这没有帮助。
这是我的配置:
@ComponentScan
@EnableAutoConfiguration
@EnableHypermediaSupport
@EnableSpringDataWebSupport
public class ApplicationConfig {
@Bean
public DataSource dataSource() {
DriverManagerDataSource datasource = new DriverManagerDataSource();
datasource.setDriverClassName("org.postgresql.Driver");
datasource.setUrl("jdbc:postgresql://localhost/mydatabase");
datasource.setUsername("myusername");
datasource.setPassword("mypassword");
return datasource;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
lef.setDataSource(dataSource);
lef.setJpaVendorAdapter(jpaVendorAdapter);
lef.setPackagesToScan("my.domain.package");
Properties jpaProperties = new Properties();
jpaProperties.setProperty("hibernate.hbm2ddl.auto", "update");
lef.setJpaProperties(jpaProperties);
return lef;
}
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
hibernateJpaVendorAdapter.setShowSql(false);
hibernateJpaVendorAdapter.setGenerateDdl(true);
hibernateJpaVendorAdapter.setDatabase(Database.POSTGRESQL);
return hibernateJpaVendorAdapter;
}
@Bean
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager();
}
public static void main(String[] args) {
SpringApplication.run(ApplicationConfig.class, args);
}
}
使用 --debug 我得到了这个(有些过滤):

最佳答案
您的配置不是 @Configuration
类。
接下来,我建议您使用 Spring Boot 的强大功能。这意味着我建议删除除 DataSource
配置之外的所有内容,只需添加具有以下属性的 application.properties 文件
spring.jpa.database=POSTGRESQL
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update
这应该会为您提供所需的行为,而编码更少。
如果您的类路径中有 commons-dbcp 或 tomcat-pool 并添加以下属性,您甚至可以删除数据源
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost/mydatabase
spring.datasource.username=myusername
spring.datasource.password=mypassword
