Cannot find class [org.springframework.http.converter.json.Jackson2ObjMapperFactoryBean]

Question

I am working on a simple demo project and after fixing multiple erroes now i am stuck here, bean declaration couldn't find class org.springframework.http.converter.json.Jackson2ObjMapperFactoryBean .I couldn't make head or tail of the error as i see all declared properly. May be someone experienced can point out the mistake here. A detailed explanation would be nice.

i am using spring 5.3.13 java 11 tomcat 9

Error :

Answer 1

It seems there is a typo. It should be Jackson2ObjectMapperFactoryBean instead of Jackson2ObjMapperFactoryBean.
