Disable table recreation in Spring Boot application - spring

Question

I'm trying to build a simple web application using Spring Boot. When I restart the application all database tables are recreated. I tried setting hibernate.hbm2ddl.auto to update or validate but that doesn't help.
This is my configuration:
#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);
}
}
Using --debug I get this (somewhat filtered):

Answer 1

Your configuration isn't a #Configuration class.
Next to that I suggest that you use the power of Spring Boot. Which means I would suggest removing everything but the DataSource configuration and simply add an application.properties file with the following properties
spring.jpa.database=POSTGRESQL
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update
This should give you the desired behavior, with less coding.
You could even remove the datasource if you have either commons-dbcp or tomcat-pool in your classpath and adding the following properties
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost/mydatabase
spring.datasource.username=myusername
spring.datasource.password=mypassword

Answer 2

If you are using spring boot, you could do it by configuration over the config file. Hibernate has all this possibilities:
validate (validate the schema)
update (update the schema if are changes)
create (create the schema)
create-drop (create the schema and drop it at the end)
but if you want don't do anything, spring boot add other chance, use as follow:
spring:
jpa:
hibernate:
ddl-auto: none

Answer 3

Your ApplicationConfig is not #Configuration. I imagine that means the Spring Boot autoconfig will also be applied. Can you try adding that?

Answer 4

If you are using a in-memory database then every time you start/stop spring boot application - it will recreate the whole thing unless you mention/configure spring boot to use the database from file system.
update your #Configuration or application.properties for below property
spring.datasource.url=jdbc:h2:file:/Users/user_name/database_file_name
Also check, you should not have spring.datasource.initialization-mode in config.
