问题描述

我正在使用Spring Boot JPA，WEB和MYSQL创建我的Web应用程序.它总是说"sessionFactory或hibernateTemplate是必需的".我该如何解决?

I'm creating my web app by using spring boot JPA, WEB and MYSQL. It always says that "sessionFactory or hibernateTemplate is required". How can I fix it?

我已经尝试过的东西:

  1. 已删除本地Maven存储库中处于休眠状态的核心的路径

  1. Deleted path where hibernate core on in local maven repo

将spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext放入application.properties

Put spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext in application.properties

将@Autowired private SessionFactory sessionFactory;放入HibernateDaoSupport扩展

Put @Autowired private SessionFactory sessionFactory; in HibernateDaoSupport extends

创建了EntityManageConfig和SessionConfig文件

EntityManageConfig.java: 

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "entityManageFactoryPrimary",
        transactionManagerRef = "transactionManagerPrimary",
        basePackages = {"com.coolspen.rjb.dao"}
)
public class EntityManageConfig {

    @Autowired
    @Qualifier("myDataSource")
    private DataSource myDataSource;

    @Primary
    @Bean(name = "entityManagerPrimary")
    public EntityManager entityManager(EntityManagerFactoryBuilder builder){
        return entityManageFactory(builder).getObject().createEntityManager();
    }   

    @Primary
    @Bean(name = "entityManageFactoryPrimary")
    public LocalContainerEntityManagerFactoryBean entityManageFactory(EntityManagerFactoryBuilder builder){
        LocalContainerEntityManagerFactoryBean entityManagerFactory =  builder.dataSource(myDataSource)
                .packages("com.coolspen.rjb.model").build();
        Properties jpaProperties = new Properties();
        jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        jpaProperties.put("hibernate.physical_naming_strategy", "org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy");
        jpaProperties.put("hibernate.connection.charSet", "utf-8");
        jpaProperties.put("hibernate.show_sql", "false");
        jpaProperties.put("hibernate.current_session_context_class", "org.springframework.orm.hibernate5.SpringSessionContext");
        entityManagerFactory.setJpaProperties(jpaProperties);
        return entityManagerFactory;
    }

    @Primary
    @Bean(name = "transactionManagerPrimary")
    public PlatformTransactionManager transactionManager(EntityManagerFactoryBuilder builder) {
        return new JpaTransactionManager(entityManageFactory(builder).getObject());
    }   

}

SessionConfig.java: 

@Configuration
public class SessionConfig {    
@Autowired
    @Qualifier("myDataSource")
    private DataSource myDataSource;

    @Bean
    public HibernateTransactionManager getTransationManager() {
        return new HibernateTransactionManager(getSessionFactory());
    }

    @Bean
    public SessionFactory getSessionFactory() {
        LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(myDataSource);
        builder.scanPackages("com.coolspen.rjb.dao");
        Properties hibernateProperties = new Properties();
        hibernateProperties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
        builder.addProperties(hibernateProperties);
        return builder.buildSessionFactory();
    }
}

DepartmentDao.java 

@SuppressWarnings(value = "all")
@Repository
public class DepartmentDao extends BaseHibernateDao<Department,java.lang.Integer>{

    public Class getEntityClass() {
        return Department.class;
    }

    public Page<Department> findPage(DepartmentQuery query) {

        StringBuilder hqlSb = new StringBuilder("SELECT t FROM  Department t WHERE 1=1 ");
        if(isNotEmpty(query.getDepartmentid())) {
            hqlSb.append(" AND  t.departmentid = :departmentid ");
        }
        if(isNotEmpty(query.getDepartmentName())) {
            hqlSb.append(" AND  t.departmentName = :departmentName ");
        }
        if(isNotEmpty(query.getRemark())) {
            hqlSb.append(" AND  t.remark = :remark ");
        }
        if(isNotEmpty(query.getCreatedateBegin())) {
            hqlSb.append(" AND  t.createdate >= :createdateBegin ");
        }
        if(isNotEmpty(query.getCreatedateEnd())) {
            hqlSb.append(" AND t.createdate <= :createdateEnd ");
        }
        if(isNotEmpty(query.getCreator())) {
            hqlSb.append(" AND  t.creator = :creator ");
        }
        if(isNotEmpty(query.getModifier())) {
            hqlSb.append(" AND  t.modifier = :modifier ");
        }
        if(isNotEmpty(query.getModifydateBegin())) {
            hqlSb.append(" AND  t.modifydate >= :modifydateBegin ");
        }
        if(isNotEmpty(query.getModifydateEnd())) {
            hqlSb.append(" AND t.modifydate <= :modifydateEnd ");
        }
        if(isNotEmpty(query.getIsAvaliable())) {
            hqlSb.append(" AND  t.isAvaliable = :isAvaliable ");
        }
        if(isNotEmpty(query.getIsDeleted())) {
            hqlSb.append(" AND  t.isDeleted = :isDeleted ");
            }
        System.out.println("finished1");
        return pageQuery(hqlSb.toString(),query);
    }

推荐答案

该异常是由于HibernateDaoSupport中的HibernateTemplate为空.您必须调用HibernateDaoSupport#setSessionFactory(sessionFactory)来初始化HibernateTemplate.

The exception is due to the HibernateTemplate inside HibernateDaoSupport is being null. You have to call HibernateDaoSupport#setSessionFactory(sessionFactory) to initialise that HibernateTemplate.

使用构造函数注入sessionFactory，然后调用此setter初始化HibernateTemplate:

Use constructor to inject sessionFactory and then call this setter to initialise HibernateTemplate:

public abstract class BaseHibernateDao<E, PK extends Serializable>
    extends HibernateDaoSupport implements EntityDao<E, PK> {

     @Autowired
     public BaseHibernateDao(SessionFactory sessionFactory){
        super.setSessionFactory(sessionFactory);
     }
 }

您的实际DAO课:

@Repository
public class DepartmentDao extends BaseHibernateDao<Department,java.lang.Integer>{

    public DepartmentDao(SessionFactory sessionFactory) {
          super(sessionFactory);
     }
}
