我在尝试通过浏览器访问我的应用时遇到了很多错误。错误是：

  

无法自动装配方法：public void   com.ProjectOne.Util.CustomHibernateDaoSupport.anyMethodName（org.hibernate.SessionFactory实例）;   嵌套异常是   org.springframework.beans.factory.NoSuchBeanDefinitionException：没有   找到类型[org.hibernate.SessionFactory]的限定bean   依赖性：预计至少为1

帐户模型

@Entity
@Table(name = "account")
public class Account {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "first_name")
    private String firstName;

    @Column(name = "last_name")
    private String lastName;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

}

的AccountService 

package com.ProjectOne.Account.Service;

import com.ProjectOne.Account.Model.Account;

public interface accountService {

    public Account retrieveAccount(Long id);
}

accountServiceImpl 

@Service("accountService")
public class accountServiceImpl implements accountService {

    @Autowired
    private accountDAO accountDAO;

    @Override
    public Account retrieveAccount(Long id) {
        return accountDAO.retrieveAccount(id);
    }
}

accountDAO 

package com.ProjectOne.Account.DAO;

import com.ProjectOne.Account.Model.Account;


public interface accountDAO {

    public Account retrieveAccount(Long id);
}

accountDAOImpl 

@Repository("accountDAO")

    public Account retrieveAccount(Long id) {

        return null;
    }

}

CustomDaoHibernateSupport 

public abstract class CustomHibernateDaoSupport extends HibernateDaoSupport
{    
    @Autowired
    public void anyMethodName(SessionFactory sessionFactory)
    {
        setSessionFactory(sessionFactory);
    }

当您尝试将引用（在您的情况SessionFactory）中自动装配到多个相同类型的bean时，通常会发生这种情况。因此，请尝试按如下方式更改方法：

@Autowired
public void anyMethodName(@Qualifier("sessionFactory")SessionFactory sessionFactory){
    setSessionFactory(sessionFactory);
}
