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？
我已经尝试过的东西：
已删除本地Maven存储库中处于休眠状态的核心的路径
将spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext放入application.properties
将@Autowired
private SessionFactory sessionFactory;中的HibernateDaoSupport放入
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);
}
}
BaseHibernateDao.java
@SuppressWarnings(value = "all")
public abstract class BaseHibernateDao<E, PK extends Serializable>
extends
HibernateDaoSupport implements EntityDao<E, PK> {
/**

protected Log log = LogFactory.getLog(getClass());

@Autowired

答案 0 :(得分：0)
该异常是由于HibernateTemplate中的HibernateDaoSupport为空。您必须调用HibernateDaoSupport#setSessionFactory(sessionFactory)来初始化HibernateTemplate。
使用构造函数注入sessionFactory，然后调用此setter初始化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类：
@Repository
public class DepartmentDao extends BaseHibernateDao<Department,java.lang.Integer>{
public DepartmentDao(SessionFactory sessionFactory) {
super(sessionFactory);
}
}
