vấn đề là biến env không tiêm và luôn luôn là null.
Tôi đã không làm bất cứ điều gì về việc thiết lập môi trường kể từ khi tôi không biết nếu nó cần thiết hoặc làm thế nào để. Tôi nhìn vào ví dụ nhà kính và tôi không tìm thấy bất cứ điều gì đặc biệt cho Môi trường. Tôi nên làm gì để đảm bảo rằng env được tiêm?

trong applicationcontext.xml, nó chỉ nhập khẩu hai XMLs để bộ nhớ cache config và cassandra, vì vậy nó có thể không quan trọng.
