prefix: SS is understood as Spring Framework and Spring MVC rather than Struts .
SSM , SSH compared to Spring Boot , where is the old?
these two abbreviations are not two sets of frameworks, they are two schemes with Spring as the core.
if we make the following settings:
Spring Framework : CPU, persistence layer: hard disk, Spring MVC : nuclear display (why nuclear display? Because this thing is included in Spring Framework in the official definition)
then SSM and SSH are just two assembly machines, while Spring Boot is a laptop with external solid state when paired with Spring Data JPA .
Can you say that the assembly machine is very old? Where is it after the update of the version number?so it's not a matter of old or new technology at all, but you need to figure out what these things are. What you need to learn is Spring Framrwork and Hibernate / MyBatis . You don't understand this, and you look confused when you open the cover of Spring Boot > which is encapsulated and integrated.
for example, I don't want to use @ Controller + @ ResponseBody + handler method (this concept is mentioned by Spring MVC ). I want to define my own routing mechanism so that I can access my performance statistics, log tracking, permission control, etc., but at the same time, I don't want to do url parsing (such as / {a} / b ), that is, I want to reuse the implementation of Spring . How do you do that?
talk about my ssm and ssh
ssm: Spring + Spring MVC + Mybatis
ssm: Spring + Structs + Hibernate
what do you think springboot is?
