Tôi đang sử dụng Spring MVC 3.1.0M2 và cố gắng di chuyển các cấu hình của mình sang các hạt java. Nhưng tôi gặp phải lỗi sau:Mùa xuân 3.1: DataSource không được tự động chuyển sang lớp @Configuration

tôi cũ pect rằng bean dataSource
sẽ được tạo sau khi nhập datasource.xml
nhưng tôi luôn gặp phải lỗi này.
TIA
Có lẽ cái gì là sai với hồ sơ? Bạn đã thử chạy nó mà không có chúng? – axtavt
@axtavt khi tôi xóa hồ sơ và chỉ để lại 'dataSource' với' jdbc: embedded-database' Tôi gặp lỗi tương tự. –
