org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyController':

提问by Zouhair Kasmi

I am doing spring + hibernate application. When I run the application on tomcat server I am getting some exceptions.

我正在做 spring + hibernate 应用程序。当我在 tomcat 服务器上运行应用程序时，出现了一些异常。

Copied from the stacktrace:

从堆栈跟踪复制：

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

BeanInstantiationException：无法实例化 bean 类 [com.gestEtu.project.model.dao.CompteDAOHib]：未找到默认构造函数；嵌套异常是 java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHibhas a constructor with a SessionFactoryargument. By adding the @Autowiredannotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactoryin your case, and provide it as a constructor argument, e.g.

默认情况下，Spring 将尝试通过调用默认（无参数）构造函数来实例化 bean。您的情况的问题是 的实现CompteDAOHib具有带SessionFactory参数的构造函数。通过向@Autowired构造函数添加注释，Spring 将尝试SessionFactory在您的情况下找到匹配类型的 bean ，并将其作为构造函数参数提供，例如

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}

回答by Sajan Chandran

Exception clearly indicates the problem.

异常清楚地表明了问题。

CompteDAOHib: No default constructor found

CompteDAOHib: No default constructor found

For spring to instantiate your bean, you need to provide a empty constructor for your class CompteDAOHib.

为了让 spring 实例化你的 bean，你需要为你的 class 提供一个空的构造函数CompteDAOHib。

回答by geddamsatish

Change from @Controller to @Service to CompteController and add @Service annotation to CompteDAOHib. Let me know if you still face this issue.

将@Controller 更改为@Service 更改为CompteController，并在CompteDAOHib 中添加@Service 注释。如果您仍然面临这个问题，请告诉我。

If nothing happens even if you added all the annotation needed, try to add this dependency to your pom.xml, I just faced the same problem and resolved it by adding this one here:

如果即使您添加了所有需要的注释也没有任何反应，请尝试将此依赖项添加到您的pom.xml.
