在Spring Boot应用程序中禁用表重新创建

标签： spring hibernate postgresql jpa spring-boot

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，将重新创建所有数据库表。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（有点过滤）：

4 个答案:

答案 0 :(得分：19)

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

这应该可以为您提供所需的行为，而且编码更少。

如果类路径中有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

答案 1 :(得分：6)

如果您使用的是spring boot，则可以通过配置文件进行配置。 Hibernate拥有所有这些可能性：

  1. 验证（验证架构）
  2. 更新（如果有更改，则更新架构）
  3. 创建（创建架构）
  4. create-drop（创建架构并将其放在最后）

    5. 但是如果你不想做任何事情，春季启动增加其他机会，使用如下：

    spring:
  jpa:
    hibernate:
      ddl-auto: none

答案 2 :(得分：0)

ApplicationConfig不是@Configuration。我想这意味着Spring Boot autoconfig也将被应用。你能尝试添加吗？

答案 3 :(得分：0)

如果您使用的是内存数据库，则每次启动/停止spring boot应用程序时-除非您提到/配置spring boot以使用文件系统中的数据库，否则它将重新创建整个内容。

为以下属性更新您的@Configuration或application.properties 

spring.datasource.url=jdbc:h2:file:/Users/user_name/database_file_name

还请检查，配置中不应包含spring.datasource.initialization-mode。
