I'm having an application here based on Spring MVC. My workmate (btw he's not here) configured it programmatically and everything seems to work, except for the TransactionManager. I have never configured a Spring web application like this and I have no clue what to do and also can not find any documentation about how to configure a webapplication like this.
I'll just show you the 'AppInitializer' and the 'EntityManagerConfig'.
AppInitializer:
public class AppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext context;
ServletRegistration.Dynamic dispatcherServletRegistration;
FilterRegistration.Dynamic encodingFilterRegistration, compressionFilterRegistration;
Set<SessionTrackingMode> sessionTrackingModes = new HashSet<SessionTrackingMode>();
sessionTrackingModes.add(SessionTrackingMode.SSL);
context = new AnnotationConfigWebApplicationContext();
context.setServletContext(servletContext);
context.scan("de.devbliss.doc");
servletContext.addListener(new ContextLoaderListener(context));
servletContext.addListener(new Log4jConfigListener());
dispatcherServletRegistration = servletContext.addServlet("main", new DispatcherServlet(context));
dispatcherServletRegistration.setLoadOnStartup(1);
dispatcherServletRegistration.addMapping("/*");
encodingFilterRegistration = servletContext.addFilter("encodingFilter", CharacterEncodingFilter.class);
encodingFilterRegistration.setInitParameter("encoding", "UTF-8");
encodingFilterRegistration.setInitParameter("forceEncoding", "true");
encodingFilterRegistration.addMappingForUrlPatterns(null, false, "/*");
compressionFilterRegistration = servletContext.addFilter("compressionFilter", GzipFilter.class);
compressionFilterRegistration.addMappingForUrlPatterns(null, false, "/*");
compressionFilterRegistration = servletContext.addFilter("springSecurityFilterChain",
DelegatingFilterProxy.class);
compressionFilterRegistration.addMappingForUrlPatterns(null, false, "/*");
servletContext.setSessionTrackingModes(sessionTrackingModes);
}
}
EntityManagerConfig:
@Configuration
@PropertySource("classpath:/db.properties")
public class EntityManagerConfig {
@Bean
public DataSource dataSource(Environment env) {
BasicDataSource ds = new BasicDataSource();
ds.setUrl(env.getProperty("url", "localhost"));
ds.setUsername(env.getProperty("user", "blissdoc"));
ds.setPassword(env.getProperty("password", "s3cret"));
return ds;
}
@Bean
@Inject
public LocalSessionFactoryBean sessionFactory(DataSource dataSource) {
LocalSessionFactoryBean factory = new LocalSessionFactoryBean();
factory.setDataSource(dataSource);
return factory;
}
@Bean
public HibernateTransactionManager transactionManager(
SessionFactory sessionFactory) {
HibernateTransactionManager tm = new HibernateTransactionManager(
sessionFactory);
return tm;
}
@SuppressWarnings("unchecked")
@Bean
@Inject
public LocalContainerEntityManagerFactoryBean entityManager(
DataSource dataSource, AbstractEnvironment env) {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
HibernateJpaDialect jpaDialect = new HibernateJpaDialect();
org.springframework.core.env.PropertySource<?> source;
Iterator<org.springframework.core.env.PropertySource<?>> sources;
// jpaVendorAdapter.setDatabase(Database.MYSQL);
jpaVendorAdapter.setGenerateDdl(true);
jpaVendorAdapter.setShowSql(true);
Properties jpaProperties = new Properties();
sources = env.getPropertySources().iterator();
while (sources.hasNext()) {
source = sources.next();
if (source.getSource() instanceof Map) {
for (Map.Entry<String, String> property : ((Map<String, String>) source
.getSource()).entrySet()) {
jpaProperties.put(property.getKey(), property.getValue());
}
}
}
em.setJpaProperties(jpaProperties);
em.setDataSource(dataSource);
em.setPersistenceUnitName("blissdoc-unit");
em.setPackagesToScan("de.devbliss.doc.model");
em.setJpaDialect(jpaDialect);
em.setJpaVendorAdapter(jpaVendorAdapter);
return em;
}
// @Bean
// @Inject
// public JpaTransactionManager jpaTransactionManager(
// EntityManagerFactory entityManagerFactory) {
// JpaTransactionManager tm = new JpaTransactionManager(
// entityManagerFactory);
// return tm;
// }
@Bean
@Inject
public JpaRepositoryFactory jpaRepositoryFactory(
EntityManagerFactory entityManagerFactory) {
JpaRepositoryFactory factory = new JpaRepositoryFactory(
entityManagerFactory.createEntityManager());
return factory;
}
@Bean
@Inject
public UserRepository userRepository(
JpaRepositoryFactory jpaRepositoryFactory) {
return jpaRepositoryFactory.getRepository(UserRepository.class);
}
@Bean
@Inject
public ProjectRepository projectRepository(
JpaRepositoryFactory jpaRepositoryFactory) {
return jpaRepositoryFactory.getRepository(ProjectRepository.class);
}
}
--- Update PersistenceJPAConfig (former EntityManagerConfig):
@Configuration
@EnableTransactionManagement
@PropertySource("classpath:/db.properties")
public class PersistenceJPAConfig {
@Inject
private Environment env;
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() {
LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
factoryBean.setDataSource(dataSource());
factoryBean.setPackagesToScan(new String[] { "de.devbliss.doc" });
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter() {
{
// JPA properties
}
};
factoryBean.setJpaVendorAdapter(vendorAdapter);
return factoryBean;
}
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl(env.getProperty("url", "localhost"));
dataSource.setUsername(env.getProperty("user", "blissdoc"));
dataSource.setPassword(env.getProperty("password", "s3cret"));
return dataSource;
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactoryBean()
.getObject());
return transactionManager;
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
@Configuration
-specific counterparts of custom XML elements such as <tx:annotation-driven>
are @Enable...
annotations.
In order to enable support for @Transactional
you need to annotate your @Configuration
class with @EnableTransactionManagement
:
@Configuration
@PropertySource("classpath:/db.properties")
@EnableTransactionManagement
public class EntityManagerConfig { ... }
See also:
@EnableTransactionManagement
Have you tried to extend from TransactionManagementConfigurer
?
@Configuration
@EnableTransactionManagement
@PropertySource("classpath:/db.properties")
public class EntityManagerConfig implements TransactionManagementConfigurer {
...
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return transactionManager();
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager(entityManagerFactory());
transactionManager.setDataSource(dataSource);
transactionManager.setJpaDialect(new HibernateJpaDialect());
return transactionManager;
}
...
}
And seems like you are using Spring Data JPA, so I recommend you to use also @EnableJpaRepositories("com.your.repositories.package")
to automatically configure your Spring Data Repositories.
Hope this helps :)
