Let the editor lead you to study and learn this article "what is the difference between @ Component and @ Bean in spring-boot".

1. @ Component is used on a class

@ Component public class Student {private String name = "lkm"; public String getName () {return name;} public void setName (String name) {this.name = name;}}

2. @ Bean needs to be used in the configuration class, that is, the class needs to be annotated with @ Configuration

@ Configurationpublic class WebSocketConfig {@ Bean public Student student () {return new Student ();}}

If you want to assemble components from a third-party library into your application, there is no way to add @ Component annotations to its classes, so you can't use automated assembly solutions, but we can use @ Bean.
