黄舟 · Answer

this represents the instance object of the current class. The current class is hosted by Spring. Spring creates the instance object of the class through the reflection mechanism, so we do not need to explicitly use the key value new to create the instance object of the class

Beans in spring are singletons by default, so this refers to the controller object

高洛峰 · Answer
