My Web Application Initialize :
public class WebAppInit extends AbstractAnnotationConfigDispatcherServletInitializer {
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[]{MyRootApplicationContext.class};
}
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[]{MyDispServ.class};
}
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
I am using Root Application Context for configure Jpa configure:
@Configuration
@EnableTransactionManagement
@PropertySource("classpath:conn.properties")
@ComponentScan(basePackages = "az.mrbee.daos")
public class MyRootApplicationContext {
@Autowired
Environment env;
@Bean
public DataSource dataSource(){
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("db.driverClass"));
dataSource.setUrl(env.getProperty("db.url"));
dataSource.setUsername(env.getProperty("db.username"));
dataSource.setPassword(env.getProperty("db.password"));
return dataSource;
}
@Bean
public JpaVendorAdapter jpaVendorAdapter(){
HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
jpaVendorAdapter.setShowSql(true);
jpaVendorAdapter.setDatabase(Database.MYSQL);
return jpaVendorAdapter;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(){
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource());
emf.setJpaVendorAdapter(jpaVendorAdapter());
emf.setPackagesToScan("az.mrbee.entities");
return emf;
}
@Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory){
return new JpaTransactionManager(entityManagerFactory);
}
@Bean
public BeanPostProcessor persistenceTranslator(){
return new PersistenceExceptionTranslationPostProcessor();
}
}
Entity Class:
@Entity
@Table(name = "yoxla")
@XmlRootElement
public class Yoxla implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private int ID;
@Column(name = "ad")
private String ad;
@Column(name = "val")
private double val;
public int getID() {
return ID;
}
public void setID(int ID) {
this.ID = ID;
}
public String getAd() {
return ad;
}
public void setAd(String ad) {
this.ad = ad;
}
public double getVal() {
return val;
}
public void setVal(double val) {
this.val = val;
}
}
After configure first time I used @Repository class directly in @Controller but I got Transaction error. After that used this one:
public interface UseJpaDAO {
public Yoxla insertData(Yoxla y);
}
@Repository
@Transactional
public class UseJpaDAOImpl implements UseJpaDAO{
@PersistenceContext
private EntityManager em;
@Transactional
public Yoxla insertData(Yoxla y) {
em.persist(y);
return y;
}
}
public interface UseJpaService {
Yoxla inserDataYoxla();
}
@Service
public class UseJpaServiceImpl implements UseJpaService {
@Autowired
private UseJpaDAO jpaDAO;
public Yoxla inserDataYoxla() {
Yoxla y = new Yoxla();
y.setAd("sdsda");
y.setVal(1212);
jpaDAO.insertData(y);
return y;
}
}
That is all. After all of that when I try to use this service in Controller I get exception
@Controller
@RequestMapping(value = "/use")
public class UseJpaController {
@Autowired
UseJpaService useJpaService;
@RequestMapping(value = "/insert")
public @ResponseBody String useInsertData(){
useJpaService.inserDataYoxla();
return "Everything is okay";
}
}
Solution:
jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
