SpringBootでバッチ処理作るときにハマったことメモ

Springbootでバッチ処理を作ろうとしたときに以下のことではまったのでメモ

1. 作成したRepositoryが読み込めない！

ネットをしらべたところ、ConfigurableApplicationContext を使うべしとあったので以下のように記述

package com;

import java.io.IOException;

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

@SpringBootApplication
public class SampleApplication {

	/**
	 * メインクラス
	 *
	 * @param args
	 */
	public static void main(String[] args) {
		try {

			ConfigurableApplicationContext context = SpringApplication.run(SampleBatchService.class, args);
			SampleBatchService service = context.getBean(SampleBatchService.class);
			service.run(args);
			context.close();

		} catch (IOException e) {
			e.printStackTrace();

		} catch (InterruptedException e) {
			// TODO 自動生成された catch ブロック
			e.printStackTrace();

		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

が、RepositoryがDIできませんとのエラーが、、、

***************************
APPLICATION FAILED TO START

Description:

Field latestRateRepository in com.SampleApplication required a bean of type 'com.repository.LatestRateRepository' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.repository.LatestRateRepository' in your configuration.

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'sampleBatchService': Unsatisfied dependency expressed through field 'latestRateRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.repository.LatestRateRepository' available: expected at least 1 bean which qualifies as autowire candidate.

３日くらい格闘したところ、mainクラスとこでConfigurableApplicationContext に指定するクラスが間違っていた。。。

ConfigurableApplicationContext context = SpringApplication.run(SampleBatchService.class, args);
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　↓
ConfigurableApplicationContext context = SpringApplication.run(SampleApplication.class, args);

ここ、自クラスを指定しないといけないんですね
