java - Bean 属性 'sessionFactory' 不可写或具有无效的设置方法

Question

我有 1 个错误:

bean 类 [com.aptech.mavenspringmvc.dao.StudentDAOImpl] 的无效属性“sessionFactory”:Bean 属性“sessionFactory”不可写或具有无效的 setter 方法。 setter的参数类型是否匹配getter的返回类型？

文件DAO工具

@Repository
public class StudentDAOImpl implements StudentDAO{
    @Autowired
public SessionFactory session;

文件 DAO

@Service
public class StudentServiceImpl implements StudentService{

//@Autowired
public StudentDAO studao;

public void setStudao(StudentDAO studao) {
    this.studao = studao;
}

public StudentDAO getStudao() {
    return studao;
}

文件 Controller

@Controller
public class StudentController {
// @Autowired
private StudentService stuSer;

Answer 1

@Repository
public class StudentDAOImpl implements StudentDAO{

 @Autowired
 public SessionFactory sessionFactory;
 ....

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