Я использую следующее для конфигурации пружины 3.1:
@Configuration
@EnableTransactionManagement
public class DataConfig {
@Inject
private Environment env;
@Inject
private DataSource dataSource;
// @Bean
public SpringLiquibase liquibase() {
SpringLiquibase b = new SpringLiquibase();
b.setDataSource(dataSource);
b.setChangeLog("classpath:META-INF/db-changelog-master.xml");
b.setContexts("test, production");
return b;
}
@Bean
public EntityManagerFactory entityManagerFactory() {
LocalContainerEntityManagerFactoryBean b = new LocalContainerEntityManagerFactoryBean();
b.setDataSource(dataSource);
HibernateJpaVendorAdapter h = new HibernateJpaVendorAdapter();
h.setShowSql(env.getProperty("jpa.showSql", Boolean.class));
h.setDatabasePlatform(env.getProperty("jpa.database"));
b.setJpaVendorAdapter(h);
return (EntityManagerFactory) b;
}
@Bean
public PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor() {
PersistenceExceptionTranslationPostProcessor b = new PersistenceExceptionTranslationPostProcessor();
// b.setRepositoryAnnotationType(Service.class);
// do this to make the persistence bean post processor pick up our @Service class. Normally
// it only picks up @Repository
return b;
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager b = new JpaTransactionManager();
b.setEntityManagerFactory(entityManagerFactory());
return b;
}
/**
* Allows repositories to access RDBMS data using the JDBC API.
*/
@Bean
public JdbcTemplate jdbcTemplate() {
return new JdbcTemplate(dataSource);
}
@Bean(destroyMethod = "close")
public DataSource dataSource() {
BasicDataSource db = new BasicDataSource();
if (env != null) {
db.setDriverClassName(env.getProperty("jdbc.driverClassName"));
db.setUsername(env.getProperty("jdbc.username"));
db.setPassword(env.getProperty("jdbc.password"));
} else {
throw new RuntimeException("environment not injected");
}
return db;
}
}
проблема в том, что переменная env не вводится и всегда равна нулю.
Я ничего не сделал с настройкой среды, так как не знаю, нужна ли она или как.Я посмотрел на пример теплицы, и я не нашел ничего специально для окружающей среды.Что я должен сделать, чтобы убедиться, что env введен?

в applicationcontext.xml, он только импортировал два xmls в кеш конфигурации и cassandraтак что это может быть не важно.
