没有从 Spring Boot 应用程序调用多个 RestController

Question

我正在尝试使用两个不同的 Rest Controller 构建 Spring Boot Rest 应用程序。 我看到 DestinationController 被调用，而 CustomerController 没有。

需要你的帮助来解决这个问题。

包结构

请找到 RestController 代码

目的地控制代码：

package com.ayan.tourismSystem.controller.rest;

import java.util.List;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.ayan.tourismSystem.entity.Destination;
import com.ayan.tourismSystem.entity.wrapper.DestinationWrapper;
import com.ayan.tourismSystem.service.DestinationService;

@RestController
@RequestMapping(value="/api/destination")
public class DestinationController {

    private static final Logger logger = LoggerFactory.getLogger(DestinationController.class);

    @Autowired
    private DestinationService destinationService;

    /**

     */
    @RequestMapping(method= RequestMethod.GET, value="/region/{region}")

    }

    /**

     */
    @RequestMapping(method= RequestMethod.GET, value="/country/{country}")

    }

    /**

     * @return Destination Id (Created)
     */
    @RequestMapping(method = RequestMethod.POST, value = "/addDestination")
    public Long addDestination(@RequestBody DestinationWrapper addDestination) {
        logger.info("Add destination Service Call Started");
        if (addDestination != null) {
            String name = addDestination.getDestination().getDestinationName();
            String country = addDestination.getDestination().getCountry();
            String region = addDestination.getDestination().getRegion();

            logger.info("Values before passing to service " + name + " " + country + " " + region);
            Destination addedDestination = this.destinationService.addDestination(name, country, region);

            Long response = addedDestination.getDestinationId();

            return response;
        }
        return null;
    }

    @RequestMapping(method = RequestMethod.PUT, value = "/updateDestination")
    public Long updateDestination(@RequestBody DestinationWrapper addDestination) {
        logger.info("Update Destination Call Started");
        if (addDestination != null) {
            Long destinationId = addDestination.getDestination().getDestinationId();
            String name = addDestination.getDestination().getDestinationName();
            String country = addDestination.getDestination().getCountry();
            String region = addDestination.getDestination().getRegion();

            logger.info("Values before passing to service " + destinationId + " " + name + " " + country + " " + region);
            Destination addedDestination = this.destinationService.updateDestination(destinationId, name, country, region);

            Long response = addedDestination.getDestinationId();

            return response;
        }
        return null;
    }

    @RequestMapping(method = RequestMethod.DELETE, value = "/deleteDestination/{destinationId}")
    public void deleteDestination(@PathVariable(value="destinationId")String destinationId) {
        logger.info("Delete Destination Call Started");

            logger.info("Values before passing to service " + destinationId);
            Long id = Long.valueOf(destinationId);
            this.destinationService.deleteDestination(id);
    }
}

            }
        }

        return null;

}

Spring 应用代码

package com.ayan.tourismSystem;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(scanBasePackages = {"com.ayan.*"})
public class TourismSystemApplication {

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

}

请建议我在这里缺少什么/做错了。

Answer 1

您在 RequestMapping 中使用了不正确的属性来定义 URL 映射

@RequestMapping(name = "/customer")

应该替换为

@RequestMapping(value = "/customer")

或者只是

@RequestMapping("/customer")

name 属性只是为映射分配一个名称，而value 指定 URL 映射

Answer 2

TLDR;您不需要添加scanBasePackages，因为spring 会根据您的主类的位置查找所有子文件夹。

说明：

Spring boot 扫描组件，从您的 @SpringBootApplication 类所在的文件夹开始，在所有子文件夹之后。

单个 @SpringBootApplication 注释可用于启用 这三个功能，即：@EnableAutoConfiguration、@ComponentScan、@Configuration。

@ComponetScan 启用 @Component 扫描包 应用程序的位置。
