# 初めに

　筆者は下記書籍をもとにSpring Batchの学習を進めていましたが、情報が古く、最新のSpring Batch 5(以下V5)には対応していませんでした。V5でこの書籍の学習を進めるうえで、抑えておくべきV4とV5の相違点を共有したいと思います。また新しくV5を学習する人の手助けになれば幸いです。

# JobBuilderFactoryとStepBuildFactoryの非推奨

　JobBuilderFactoryとStepBuildFactoryは非推奨になっており、V5の構成で動作させるとエラーが発生します。
試しに期待動作として「HelloWorld」とログ出力するプログラムを実行してみると

```java:BatchConfig.java
@Configuration
@EnableBatchProcessing
public class BatchConfig {

    /** JobBuilderのFactoryクラス */
    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    /** StepBuilderのFactoryクラス */
    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    /** Helloworldをログ出力するTasklet */
    @Autowired
    private Tasklet helloTasklet;

    /** TaskletのStepを生成 */
    @Bean
    Step taskletStep1() {
        return stepBuilderFactory.get("HelloTaskletStep1") // Builderの取得
            .tasklet(helloTasklet) // Taskletのセット
            .build(); // Stepの生成
    }

    /** Jobを生成 */
    @Bean
    Job taskletJob() throws Exception {
        return jobBuilderFactory.get("HelloWorldTaskletJob") // Builderの取得
            .incrementer(new RunIdIncrementer()) // IDのインクリメント
            .start(taskletStep1()) // 最初のStep
            .build(); // Jobの生成
    }
}

```

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

Description:

Field jobBuilderFactory in com.example.demo.config.BatchConfig required a bean of type 'org.springframework.batch.core.configuration.annotation.JobBuilderFactory' 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 'org.springframework.batch.core.configuration.annotation.JobBuilderFactory' in your configuration.


```

もうBeanとしてクラスが管理されていないため、エラーになっています。
次に公式リファレンス通りにJobBuilderとStepBuilderに置き換えて動作させてみます。

```java:BatchConfig.java
@Configuration
@EnableBatchProcessing
public class BatchConfig {


  /** HelloTasklet */
  @Autowired
  private Tasklet helloTasklet;

  /** TaskletのStepを生成 */
  @Bean
  Step taskletStep1(JobRepository jobRepository, PlatformTransactionManager transactionManager) {
    return new StepBuilder("HelloTaskletStep1", jobRepository) // Builderの生成
        .tasklet(helloTasklet, transactionManager) // Taskletのセット
        .build(); // Stepの生成
  }

  /** Jobを生成 */
  @Bean
  Job taskletJob(JobRepository jobRepository, PlatformTransactionManager transactionManager)
      throws Exception {
    return new JobBuilder("HelloWorldTaskletJob", jobRepository) // Builderの生成
        .incrementer(new RunIdIncrementer()) // IDのインクリメント
        .start(taskletStep1(jobRepository, transactionManager)) // 最初のStep
        .build(); // Jobの生成
  }
}
```

しかし、公式通りの単純な置き換えを行っても期待動作はせずにプログラムは終了しています。気になるログとしては下記が挙げられます。
```shell:ログ出力
Bean 'jobRegistry' of type [org.springframework.batch.core.configuration.support.MapJobRegistry] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying). Is this bean getting eagerly injected/applied to a currently created BeanPostProcessor [jobRegistryBeanPostProcessor]? Check the corresponding BeanPostProcessor declaration and its dependencies/advisors. If this bean does not have to be post-processed, declare it with ROLE_INFRASTRUCTURE.
```
jobRegistryの設定が上手くいっていないようです。
ここで下記公式の「Updated code for Batch 5 and Boot 3」のコードを確認してみると、
https://github.com/spring-guides/gs-batch-processing/commit/ed2604bfa5b8140e0b98e0c1bd8f307e85ce2979#diff-c61a8fde67d30987ddfc8ee91fa6d180fb0f22d631a7205068bfaa7e74ac36c3L28

EnableBatchProcessingアノテーションが外されています。よって@EnableBatchProcessingを外して実行してみると

Stepが実行され、期待動作通り「Hello World」がログに出力されています。
@EnableBatchProcessingが悪さをしていたようです。
確かに下記「Spring Boot 3.0 Migration Guide」によると@EnableBatchProcessingは非推奨となっています。

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#enablebatchprocessing-is-now-discouraged

バッチの実行状況を管理するメタテーブルを初期化していた@EnableBatchProcessingですが、V5からはそれが自動的に構成されるようになり、余計に@EnableBatchProcessingをつけると挙動が変化するようです。詳しくは下記記事が参考になります。

# 番外

　Spring解体新書(バッチ編)の書籍では、application.ymlでプロパティを設定していますが、プロパティ名が誤っています。正しくは下記の通りです。これはapplication.propertiesの場合でも同様です。

```diff:application.yml
spring:
  batch:
    job:
- names: 
+ name: 
```


# 最後に

SpringBatch 5に関して、あまり情報が落ちていないので調査には苦労しました。
公式リファレンスで矛盾している内容があるので困りものですね。
実際、私は@EnableBatchProcessingの非推奨に関してギブアップしてしまい、上司のFさんに助けを求めたところ、解決していただきました。Fさんありがとうございました！
今後も業務を通して、SpringBatch 5の有益な情報が見つかったら共有しようと思います。
最後までお読みいただきありがとうございました。
