在使用spring mvc和hibernate自动装配sessionfactory bean时遇到问题 [英] Having issues autowiring a sessionfactory bean with spring mvc and hibernate
本文介绍了在使用spring mvc和hibernate自动装配sessionfactory bean时遇到问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图在我的项目中实现自动布线，但似乎我的应用程序在运行它时没有在我的application-context.xml中看到我的SessionFactory定义。
我可能错过了一些非常明显的东西，尽管我已经尝试了几个解决方案，但是发现类似的问题没有成功。
我使用Spring MVC和Hibernate。
这是我的application-context.xml。

编辑：我最终通过自动装配到接口TableEntityFetchDao中而不是实现它的类ApplicationInstanceDaoImpl来解决问题。
因此， / p>
@Autowired public ApplicationInstanceDaoImpl applicationInstanceDaoImpl;
成为这个
@Autowired public TableEntityFetchDao applicationInstanceDao;
这似乎解决了我的问题。
@Resource（name =mySessionFactory）
public void setMySessionFactory（SessionFactory mySessionFactory）{
this.mySessionFactory = mySessionFactory;
使用：
@Autowired
private SessionFactory mySessionFactory;
编辑
<
不知道为什么method不起作用，但我猜测父母 TableEntityFetchDao 类具有会话工厂的setter，然后 ApplicationInstanceDaoImpl - 子类重写它，并由于某种原因弹出不喜欢它，如果 TableEntityFetchDao @Resource 与 @Autowired 具有相同的用途，所以set c将被注入，区别在于 @Resource 允许指定注入的bean的名称， @Autowire 允许您标记bean不需要。
获得 @Resource 我会尝试从父类中移除setter方法。无论哪种方式，它没有意义，因为它没有被使用。还有sessionFactory字段。这也可以被删除。然后，类只包含抽象方法，可以作为一个接口。另外，我会用 @Service 注释来注释 TableEntityFetchDao ，以便更好地理解它是一个服务层类。
I am trying to implement auto-wiring into my project, but it seems that my application isn't seeing my SessionFactory definition in my application-context.xml when I am running it.
I'm probably missing something really obvious, though I've tried several solutions from posts having similar issues with no success.
I am using Spring MVC and Hibernate.
Here is my application-context.xml.

Edit: I ended up fixing my problem by autowiring into the interface TableEntityFetchDao rather than the class that was implementing it, ApplicationInstanceDaoImpl.
So, this
@Autowired public ApplicationInstanceDaoImpl applicationInstanceDaoImpl;
Became this
@Autowired public TableEntityFetchDao applicationInstanceDao;
And that seemed to fix my problem.
解决方案 Instead of:
@Resource(name = "mySessionFactory")
public void setMySessionFactory(SessionFactory mySessionFactory){
this.mySessionFactory = mySessionFactory;
}
Use:
@Autowired
private SessionFactory mySessionFactory;
EDIT
As of the bellow comment:
Not sure why method is not working but my guess is that the parent TableEntityFetchDao class has the setter of session factory, then ApplicationInstanceDaoImpl - child class overrides it and spring for some reason does not like it, if TableEntityFetchDao would be an interface, setter would be injected, as @Resource serves the same purpose as @Autowired difference is that @Resource allows to specify the name of the bean which is injected, and @Autowire allows you mark the bean as not required.
To get @Resource working I would try to remove setter method from the parent class. Either way it makes no sense of having it there as it is not used. Also sessionFactory field. This can be removed as well. Then class contains only abstract methods and can be made an interface. Also I would annotate TableEntityFetchDao with @Service annotation for better understanding that it is a service-layer class.
