Question

我已经按照here的说明配置了application.properties‬：

server.servlet.context-path=/test

在我的@RestController中，我有一个简单的@RequestMapping：

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

但是仍然在向http://localhost:8080/test/products发送请求时，我得到了tomcat-404响应。

完整代码：

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);
   }
}

在tomcat 9上运行，如果需要更多代码或配置，请在下面评论，谢谢。

Answer 1

任何请求都应该“知道”如何到达该控制器。我建议尝试一下：

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


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

通过这种方式，您可以向以下网址发送 GET 请求： http://localhost:8080/test/psc/products

添加@RequestMapping批注以指定此类（控制器）的路径
消除每个@RequestMapping路径值上的“ /”（只是一个修饰性建议）

Spring Boot-配置上下文路径
