剩余URL路徑未映射（Spring Boot）

Question

考慮以下問題，

引導應用程序java類：

package com.abb;

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

@SpringBootApplication(scanBasePackages = {"com.abb.repositories"})
public class ServerApplication {

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

CrudRepository接口（它只是在這里添加，因為我覺得程序包可能會導致此問題）：

package com.abb.repositories;

import org.springframework.data.repository.CrudRepository;
import com.abb.entities.XYZ;

public interface XYZRepository extends CrudRepository<XYZ, Long> { }

控制器Java類對於其余API：

package com.abb.controller;

import org.springframework.beans.factory.annotation.Autowired; 
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.ResponseBody; 
import org.springframework.web.bind.annotation.RestController;
import com.abb.repositories.XYZRepository;

@RestController 
@RequestMapping("/abc") 
public class ABCController {

     @Autowired
     private XYZRepository xyzRepository;

     @RequestMapping(value = "/test", method = RequestMethod.POST)
     public @ResponseBody String test(@RequestBody int iValue) {
          return "done" + iValue; 
     }
}

問題是您將Spring Boot掃描儀限制為僅掃描存儲庫軟件包。 不會掃描其他軟件包。 這意味着它不會選擇“ com.abb.controllers”包中的控制器。

刪除scanBasePackages屬性，替換該值，或添加要掃描的每個單獨的程序包。

我建議這樣做：

@SpringBootApplication

或這個：

@SpringBootApplication(scanBasePackages = {"com.abb"})
