Spring Boot-配置上下文路径

Question

I have configured application.properties‬ as explained here with :

server.servlet.context-path=/test

And in my @RestController I have a simple a simple @RequestMapping :

@RequestMapping(value = "/products", method = RequestMethod.GET)

But still when sending a request to http://localhost:8080/test/products I get tomcat - 404 response.

Full code:

package com.siemens;

import java.util.HashMap;
import java.util.Map;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class ProductServiceController {
   private static Map<String, Product> productRepo = new HashMap<>();
   static {
      Product honey = new Product();
      honey.setId("1");
      honey.setName("Honey");
      productRepo.put(honey.getId(), honey);

      Product almond = new Product();
      almond.setId("2");
      almond.setName("Almond");
      productRepo.put(almond.getId(), almond);
   }



   @RequestMapping(value = "/products", method = RequestMethod.GET)
   public ResponseEntity<Object> getProduct() {
      return new ResponseEntity<>(productRepo.values(), HttpStatus.OK);
   }
}

@SpringBootApplication:

@SpringBootApplication

    public static void main(String[] args) {
        SpringApplication.run(SiemensApplication.class, args);
    }
}

Running on tomcat 9, if there is more code or config needed please comment below, thank you.

Answer 1

Any request should 'know' how to get to this controller. I would suggest trying this:

@RestController
@RequestMapping("psc")
public class ProductServiceController {


    @RequestMapping(value = "products", method = RequestMethod.GET)
    public ResponseEntity<Object> getProduct() {
    return new ResponseEntity<>(productRepo.values(), HttpStatus.OK);
    }

this way you can send a GET request, to the following url: http://localhost:8080/test/psc/products

1. add the @RequestMapping annotation to specify the path to this class(controller)
2. get rid of the "/" on every @RequestMapping path value (just a cosmetic suggestion)
