Question

我在春天设置了一个事务管理器时遇到如下错误，如果我不在春天使用它，一切都运转良好

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
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.local.service.DepartmentManagerImpl] is defined

    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:985)

Spring.xml如下所示

服务类如下所示

@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，那么一切正常，

请告知我可能错过的地方

Answer 1

奇怪的行为。 DepartmentManager接口应该不是问题。
只是一个猜测：问题是不是你宣布两次交易经理：

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

和

<tx:annotation-driven/>

可能会产生副作用。您可以尝试删除其中一个并保留DepartmentManager界面。

事务管理器在Spring + Hibernate配置中失败
