Spring boot to jsp page implementation

I am learning Spring boot and have searched a lot about the implementation method of Spring boot jumping to jsp page. I will record 1 below for your reference. I hope this article has been helpful to you.

@ Controller annotations

1. Configuration in ES13en. properties file

#  configuration jsp The default location of the file is: src/main/webapp
spring.mvc.view.prefix=/pages/
#  configuration jsp File suffix 
spring.mvc.view.suffix=.jsp

2. Configuration in Controller file

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
@Controller
public class UserController {

  @RequestMapping(value = "/index",method = RequestMethod.GET)
  public String toIndex(){
    return "index";
  }
}

3. Start the method [main] in project ES24en. Java]

4. Visit url, access to jsp page: http: / / localhost: 8080 / index

@ RestController annotations

1. Configuration in ES42en. properties file

#  configuration jsp The default location of the file is: src/main/webapp
spring.mvc.view.prefix=/pages/
#  configuration jsp File suffix 
spring.mvc.view.suffix=.jsp

2. Configuration in RestController file

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
@RestController
public class UserController {

  @RequestMapping(value = "/index",method = RequestMethod.GET)
  public String toIndex(){
    ModelAndView mv = new ModelAndView("index");     
 return mv;  
  }
}

3. Start the method [main] in project ES53en. java]

4. Visit url, access to jsp page: http: / / localhost: 8080 / index

. Note: application properties in spring. mvc. view. prefix and spring mvc. view. prefix attributes in spring - boot old version and new version is not 1:
In the old version:

spring.view.prefix=/pages/ 
spring.view.suffix=.jsp

In the new version:

spring.mvc.view.prefix=/pages/
spring.mvc.view.suffix=.jsp
