org.springframework.beans.factory.BeanCurrentlyInCreationException: Lỗi khi tạo bean với tên 'sessionFactory'

Question

Tôi đang sử dụng spring và hibernate để cấu hình với db mysql. đang

tập tin we.xml của tôi đã sau:

<?xml version="1.0" encoding="UTF-8"?>

Tôi đã bao gồm lib thích hợp. Bây giờ tại thời điểm chạy dự án, tôi nhận được lỗi sau:

Có thể có bất kỳ giải pháp nào, tại sao hạt sessionFactory của tôi bị lỗi?

Cảm ơn trước ...

Answer 1

mùa xuân là nói cho bạn biết chính xác vấn đề là gì, bạn chỉ cần phải đọc các bản ghi và lỗi lồng nhau thông điệp:

Không thể giải quyết tham chiếu đến đậu 'sessionfactory' trong khi thiết lập thuộc tính bean 'sessionFactory'; lồng nhau ngoại lệ là org.springframework.beans.factory.BeanCurrentlyInCreationException: Lỗi tạo đậu với tên 'sessionfactory': FactoryBean mà hiện đang trong tạo trở null từ getObject

Một chút Google tìm kiếm gợi ý rằng lỗi này thông báo thường là kết quả của a circular dependency và cũng dẫn đến việc xóa a mailing list post that recommendsdefault-autowire="detect" từ phần tử <beans> của bạn.
