What is a Spring Bean

A "Spring Bean" is simply a Java object.

When Java objects are created by the Spring Container, then Spring refers to them as "Spring Beans".

Spring Beans are created from normal Java classes .... just like Java objects.

Here's a blurb from the Spring Reference Manual

Source: https://docs.spring.io/spring/docs/current/spring-framework-reference/core.html#beans-introduction

---

In the early days, there was a term called "Java Beans". Spring Beans have a similar concept but Spring Beans do not follow all of the rigorous requirements of Java Beans.

---

In summary, whenever you see "Spring Bean", just think Java object. :-)

Kinh nghiệm build môi trường

Dự án: website quản lý bán vé cho VFF liên đoàn bóng đá việt nam
Tôi đã có sẵn source và dump của database
Khi build project thì
build bằng dòng lệnh => lỗi
build bằng eclipse => có thể chạy được nhưng bất ổn định (lúc lỗi lúc không)
mvn clean
mvn install
Nếu build lỗi vài lân => xóa thư mục .m2 đi để mvn tự kéo về

pleiades: Tomcat JDK MySQL Eclipse setbox
