Rest URL路径未映射(Spring Boot)

spring-restcontroller spring-boot spring java

Mayur · 技术社区 · 7 年前

考虑一下,接下来的课程针对我的问题,

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(它只是添加到这里,因为我觉得包可能会导致此问题):

package com.abb.repositories;

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

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

rest API的控制器Java类:

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; 
     }
}

问题是您将spring boots scanner限制为仅扫描存储库包。不会扫描其他包裹。这意味着它不会拾取“com.abb.controllers”包中的控制器。

删除scanBasePackages属性,替换该值,或添加要扫描的每个包。

@SpringBootApplication

或者:

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