SpringBoot 1.2.1 MongoRepository

Question

ich das Problem bin unten:

AnacDetailManager.java:

package com.almundo.anac.core; 

import com.almundo.anac.domain.ANACDelay; 
import com.almundo.anac.core.ANACDelayRepository; 
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service; 

@Service 
public class ANACDetailManager { 

    @Autowired

     return anacDelay; 
    } 
} 

AnacServiceController.java:

package com.almundo.anac.service.controller;

import com.almundo.anac.domain.ANACDelay; 

@Controller 
//@RequestMapping("anacservice") 
//@ComponentScan("com.almundo.anac.core") 
@EnableMongoRepositories("com.almundo.anac.core") 
public class AnacServiceController { 

    @Autowired 
    final ANACDetailManager _manager; 

    @Autowired 
    public AnacServiceController(ANACDetailManager manager) { 
     this._manager = manager; 
    } 

    @ResponseBody 
    @RequestMapping(value = "{flightNumber}/{airCia}/{origin}/{destination}", method = RequestMethod.GET) 
    public ResponseEntity<ANACDelay> getAnacDelay(@PathVariable String flightNumber, @PathVariable String airCia, 
      @PathVariable String origin, @PathVariable String destination) { 

     ANACDelay anacDelay = _manager.FindDelay(flightNumber, airCia, origin, destination); 

     return new ResponseEntity<ANACDelay>(anacDelay, HttpStatus.OK); 
    } 

} 

Nur um zu erklären, ich baue eine Rest-API, die mein Repository aufrufen wird, um Daten aus der Datenbank zu lesen.

Vielen Dank im Voraus!

EDIT:

das Problem lösen. Ich habe in der AppInitializer.java setzen @EnableMongoRepository:

package com.almundo.anac.service; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories; 

@SpringBootApplication 
@ComponentScan({"com.almundo.anac.core", "com.almundo.anac.service"}) 
@EnableMongoRepositories("com.almundo.anac.core") 
public class AppInitializer{ 

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

} 

Answer 1

Sieht aus wie Sie die Repository-Schnittstelle für Ihre Domain sind vermisst.

public interface YourRepository extends MongoRepository<ANACDelay, String> {} 

und dieses Repository in den Manager autowired.

Answer 2

Sie benötigen eine Schnittstelle innerhalb des Pakets com.almundo.anac.core

package com.almundo.anac.core; 

public interface ANACDelayRepository extends MongoRepository<ANACDelay, String> { 

} 

Dann sollten ANACDetailManager so sein zu erstellen:

@Service 
public class ANACDetailManager { 

    @Autowired 
    public ANACDelayRepository _repository; 

    public ANACDelay FindDelay(String flightNumber, String airCia, String origin, String destination) { 
     String key = airCia + flightNumber + origin + destination; 
     ANACDelay anacDelay = _repository.findOne(key); 

     return anacDelay; 
    } 
}
