Add prefix or suffix to the GET,PUT,POST,DELETE mappings in controller at method level using custom annotation - Spring REST Controller

I am trying to add a prefix or suffix in the controller at the method level on top of GET, POST, PUT, DELETE mappings.
Controller class
#RestController
#RequestMapping("/something")
public class SomeController {
#PutMapping("/some/path/")
public ResponseEntity<ApiResponse<String>> someMethod() {
....
}
...
}
So, basically, the above request URL should be something like : http://localhost:8080/something/some/path/
Now, I just want to add some prefix or suffix whatever is feasible to the request URL which will be something like : http://localhost:8080/something/read/some/path/ or http://localhost:8080/something/some/path/read/ the extra "/read" which needs to be added to the request URL as a prefix or suffix. I can do this directly by adding this to the PutMapping value, but I want to decorate it somewhat using annotation like #Read
So, the updated Controller class will be like
#RestController
#RequestMapping("/something")
public class SomeController {
#Read
#PutMapping("/some/path/")
public ResponseEntity<ApiResponse<String>> someMethod() {
....
}
...
}
and the same way updated request URL will be like : http://localhost:8080/something/read/some/path/
I am unable to find a better way to do this. Till now I have only achieved adding a class-level prefix using custom annotation.
Can anyone please help with the above requirement.?
Thank you !!
I am also curious to know whether is achievable or not even?

Using such way of path extension make your code less understandable. (maybe you should read more about RESTful API) But spring can do almost everything you want.
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.servlet.WebMvcRegistrations;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.lang.reflect.Method;
import java.util.stream.Stream;
#SpringBootApplication
public class DemoApplication {
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.METHOD)
public #interface Read {
}
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.METHOD)
public #interface Write {
}
#Bean
public WebMvcRegistrations webMvcRegistrations() {
return new WebMvcRegistrations() {
#Override
public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
return new RequestMappingHandlerMapping() {
#Override
protected RequestMappingInfo getMappingForMethod(Method method, Class<?> handlerType) {
RequestMappingInfo defaultRequestMappingInfo = super.getMappingForMethod(method, handlerType);
if (defaultRequestMappingInfo == null) {
return null;
}
String pathSuffix;
if (method.isAnnotationPresent(Read.class)) {
pathSuffix = "read";
} else if (method.isAnnotationPresent(Write.class)) {
pathSuffix = "write";
} else {
return defaultRequestMappingInfo;
}
//extend path by mutating configured request mapping info
RequestMappingInfo.Builder mutateBuilder = defaultRequestMappingInfo.mutate();
mutateBuilder.paths(
defaultRequestMappingInfo.getPatternValues().stream()
.map(path -> path + "/" + pathSuffix)
.toArray(String[]::new)
);
return mutateBuilder.build();
}
};
}
};
}
#RestController
#RequestMapping("/books")
public static class BooksController {
#Read
#GetMapping("/{id}")
public String readBook(#PathVariable("id") String bookId) {
return bookId;
}
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
Extension point is here, you can change path like you want.
Example:
request: http://localhost:8080/books/asd
response: 404
output:
2022-06-27 10:49:48.671 DEBUG 8300 --- [nio-8080-exec-2] com.example.demo.DemoApplication$1$1 : Mapped to org.springframework.boot.autoconfigure.web.servlet.error.BasicErrorController#errorHtml(HttpServletRequest, HttpServletResponse)
request: http://localhost:8080/books/asd/read
response: asd

Please attach request from e.g. the developers' tools with HTTP verb that you are using and exact response from that request. I am concerned about #GetMapping - why it is in curly braces?
About post mapping, maybe you should describe consumes and produces part of mapping?
E.g.
#PostMapping(path = "/members", consumes = "application/json", produces = "application/json")
I have never used #PostMapping annotation without those parts.
UPDATE:
After removal of unnecessary component scan in Main class change controller as follow:
#RestController
public class ControllerRest {
#Autowired
private MessagesRepository msgRepo;
RestTemplate restTemplate;
#GetMapping({ "/StatusData" })
public List<Messages> index() {
return this.msgRepo.findAll();
}
#PostMapping(path = {"/postdata"})
public ResponseEntity<Messages> createBody(#RequestBody Map<String, String> body) {
Messages msgDao = new Messages();
msgDao.setTemplate((String) body.get("template"));
msgDao.setParameters((String) body.get("parameters"));
msgDao.setHsm((String) body.get("hsm"));
msgDao.setTo((String) body.get("to"));
return new ResponseEntity<Messages>(this.msgRepo.save(this.HttpStatus.OK);
}
}

Add a context path to your application.properties file or application.yml, whichever you are using.
server.servlet.contextPath=/springbootapi
Hit your endpoint: The endpoint for your POST method will be:
http://localhost:{PORT}/springbootapi/postdata
Why dont you statically supply your port. I think the port should be something like:
server.port=8080

I don't understand why you using #RequestBody with "Map<String,String>".
Try this code :
#Autowired
private MessagesRepository msgRepo;
#PostMapping("/postdata")
public ResponseEntity<Object> createBody(#RequestBody Message message) {
Message saveMessage= msgRepo.save(message);
URI location = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}")
.buildAndExpand(saveMessage.getId()).toUri();
return ResponseEntity.created(location).build();
}

The problem is that you are using wrong annotation i.e #component.
Remove this annotation and use #Entity.
This is your code.
After executing this code check the logs, you will see no sql create query is fired by hibernate.
package com.example.demo.hibernateDemoEntity;
import javax.persistence.*;
import org.springframework.stereotype.Component;
#Component
#Table
public class Bookmodel {
#Id
private int id;
#Column
private String name;
#Column
private String isbn;
#Column
private String author;
#Column
private String pages;
}

Now you can see sql create query is fired by hibernate.

You are "using" Spring Boot and the first thing you do is try very hard not to use Spring Boot.
Instead of doing all the configuration by yourself let Spring Boot do the heavy lifting for you.
In your application.properties set the proper dialect and use the correct properties (see this section of the Spring Boot Reference Guide for a full list of properties).
# Database
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/bookdetails
spring.datasource.username=postgres
spring.datasource.password=admin
# Hibernate
spring.jpa.database=org.hibernate.dialect.PostgreSQL94Dialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create
And remove your custom configuration (i.e. the AppConfig and SettingConfig) that breaks the auto configuration of Spring Boot.

I don't see any column definition in your POJO, how do you expect hibernate to know what type of column to create by simply give a Java type such as String? For my MySQL database I would define POJO like this
#Component
#Table(name = "Book")
public class Bookmodel {
#Size(max = 32)
#Id
#Column(columnDefinition = "varchar(128)", nullable = false, unique = true)
private String id;
#Column(columnDefinition = "varchar(128)", nullable = false)
private String name;
...
}
