事务管理器在 Spring+Hibernate 配置中失败

Question

我在春季设置事务管理器时遇到如下错误， 如果我在春天不使用它，一切都很好

Aug 20, 2016 3:45:53 PM org.springframework.orm.hibernate4.HibernateTransactionManager afterPropertiesSet
INFO: Using DataSource [org.springframework.jdbc.datasource.DriverManagerDataSource@3148f668] of Hibernate SessionFactory for HibernateTransactionManager

    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:319)
    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:985)

Spring.xml 如下所示

服务类如下

@Service
    public class DepartmentManagerImpl implements DepartmentManager {

        private DepartmentDAO departmentDAO;

        @Override
        @Transactional
        public List<Department> getAllDepartments() {

            return departmentDAO.getAllDepartments();

        }

        @Autowired
        public void setDepartmentDAO(DepartmentDAO departmentDAO) {
            this.departmentDAO = departmentDAO;
        }
.....
}



@Repository
public class ImplDepartment implements DepartmentDAO {

    private SessionFactory sessionFactory;

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    @Autowired
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

public interface DepartmentDAO {

    public void addDepartment(Department department);

    public void editDepartment(Department department);

    public void deleteDepartment(Integer department);

    public Department getDepartmentById(Integer department_id);

    public List<Department> getAllDepartments();

    public void addEmployee(Department department, Employee employee);

}


public interface DepartmentManager {

    public void addDepartment(Department department);

    public void editDepartment(Department department);

    public void deleteDepartment(Integer department);

    public Department getDepartmentById(Integer department_id);

    public List<Department> getAllDepartments();

    public void addEmployee(Department department, Employee employee);

}

如果我不使用事务管理器，一切正常，

请告诉我在这里可能错过了什么

Answer 1

奇怪的行为。 DepartmentManager 接口应该不是问题。
只是猜测：问题不是你声明两次吗 事务管理器：

<tx:annotation-driven transaction-manager="transactionManager"/>

和

<tx:annotation-driven/>

也许它会产生副作用。 您可以尝试删除其中一个并保留DepartmentManager 接口。
