Spring Config Setting

Set Properties. And Use @Value Annotation

[1] Add @PropertySource Annotation at RootApplicationConfig.class

@Configuration
@PropertySource(value = "classpath:properties/default.properties")
public class RootApplicationConfig {
}

[2] Add default.properties file at resources directory

[3] If you user @Value Annotation. Add below code in RootApplicationConfig.class

@Bean
public PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
	return new PropertySourcesPlaceholderConfigurer();
}

Set @Transactional

[1] Add PlatformTransactionManager Implement class. So I add DataSourceTransactionManager class bean create.

@Bean
public DataSourceTransactionManager dataSourceTransactionManager() {
	return new DataSourceTransactionManager(dataSource);
}

[2] Add @EnableTransactionManagement Annotation at java config class. ( If you use xml, you add 'tx:anntoation-driven') [Link] Docs

@Configuration
@EnableTransactionManagement()
public class JdbcTemplateConfig {
	...
}

[3] Add @Transactional Annotation. Now I implement only repository so I add this repoistory Class.

@Repository
public class BoardRepositoryImpl implements BoardRepository {
	...
	@Override
	@Transactional(readOnly = true, propagation = Propagation.REQUIRED, isolation = Isolation.SERIALIZABLE)
	public Board insert(Board board) {
		...
	}
}
