Answer 1

:

BeanInstantiationException : 콩 클래스를 인스턴스화 할 수 없습니다 [com.gestEtu.project.model.dao.CompteDAOHib] : 없음 기본 생성자를 찾을 수 없음; 중첩 예외는 java.lang.NoSuchMethodException : com.gestEtu.project.model.dao.CompteDAOHib입니다. < 초기화하기 >() 기본적으로

, 봄은 기본 (인수 없음) 생성자를 호출하여 빈을 인스턴스화하려고합니다. 귀하의 경우 문제는 CompteDAOHib의 구현에 SessionFactory 인수가있는 생성자가 있다는 것입니다. @Autowired 주석을 생성자에 추가하면 Spring은 일치하는 유형의 bean 인 bean을 찾은 다음 생성자 인수로 제공합니다 (예 : SessionFactory).

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

Answer 2

예외는 분명히 문제가 있음을 나타냅니다. 여러분의 빈을 인스턴스화하는 봄

CompteDAOHib: No default constructor found

, 당신은 클래스 CompteDAOHib에 대한 빈 생성자를 제공해야합니다.

Answer 3

@Controller에서 @Service를 CompteController로 변경하고 을 CompteDAOHib에 @Service 주석을 추가하십시오. 이 문제가 계속되면 알려주세요. 스택 트레이스에서 복사

Answer 4

org.springframework.beans.factory.BeanCreationException : 이름을 가진 bean을 생성 오류 'MyController에'

당신이 당신의 라이브러리에 ojdbc14.jar를 추가했는지 확인하십시오.

여기서 oracle11g을 사용하고 있는데,이 경우 ojdbc14.jar이 없습니다. 내가 무엇을 할 수 있을지?

Answer 5

비슷한 오류가 발생하여 공유하고 싶습니다. 어쩌면 그것은 누군가를 도울 것입니다.

당신이 EntityManager를 얻을 수 EntityManagerFactory를 사용하려는 경우, 당신이 사용하는지 확인하십시오

<persistence-unit name="name" transaction-type="RESOURCE_LOCAL"> 

하지 : persistance.xml

청소에

<persistence-unit name="name" transaction-type="JPA"> 

을하고 프로젝트를 다시 빌드, 도움이 될 것입니다.
