其余 URL 路径未映射（Spring 启动）

Question

考虑一下，按照 classes 解决我的问题，

启动应用程序javaclass：

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（它只是添加在这里，因为我觉得包可能会导致这个问题）：

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 Class 休息 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; 
     }
}

Answer 1

问题是您限制 spring 启动扫描器只扫描存储库包。不会扫描其他包裹。这意味着它不会拾取你的控制器，它们在 "com.abb.controllers" 包中。

删除 scanBasePackages 属性，替换值，或添加您要扫描的每个包。

我推荐这个：

@SpringBootApplication

或者这样：

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