Question

我必须创建批处理作业，这些作业需要根据作业参数创建一些配置Bean，因此我无法在应用程序的开头实例化它们。

我尝试遵循我发现的一些示例，但没有一个奏效。有人知道如何解决这个问题吗？

@SpringBootApplication
@EnableConfigurationProperties
@EnableBatchProcessing
public class Application {

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

作业配置：

@Configuration
@Slf4j
public class JobConfiguration {
    @Autowired
    private JobBuilderFactory jobs;

    @Autowired
    private StepBuilderFactory steps;

    /***
     * This job will create/update the resources in AWS accordingly with the
     * configuration provided.
     * 
     * @return the job
     */
    @Bean
    @Qualifier("NetworkJob")
    @Primary
    public Job createJob() {
    return jobs.get("Start Job").start(dummyTasklet()).build();
    }

    /***
     * Create a step to verify if a service role exists or to create it if not.
     * 
     * @return the step
     */
    @Bean
    @JobScope
    public Step dummyTasklet() {
    return steps.get("Dummy").tasklet((contribution, chunkContext) -> {
        log.info("And I run ... ");
        return RepeatStatus.FINISHED;
    }).build();
    }

}

和一些JobScope bean：

@Configuration
@Slf4j
public class GitConfiguration {
    @Bean
    @Qualifier("GITPath")
    @JobScope
    public String getGitTemporaryPath() {
    return "/tmp/path";
    }

    @JobScope
    @Bean
    public Git getCustomerGitRepository(@Value("#{jobParameters[customerRepository]}") String customerRepository,
        @Value("#{jobParameters[customerBranch]}") String customerBranch,
        @Value("#{jobParameters[vaultSecretPath]}") String vaultSecretPath,
        @Value("#{jobParameters[id]}") String id) {

    return Git.cloneRepository().setURI(customerRepository)
        .setDirectory(new File(getGitTemporaryPath() + id)).setBranch(customerBranch)
        .setCredentialsProvider(credentialsProvider).call();
    }

    @Bean
    @JobScope
    public PropertySourcesPlaceholderConfigurer properties(Git repository) {
       PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
       val path = repository.getRepository().getWorkTree().getAbsolutePath()
        + "file.yml";
    propertySourcesPlaceholderConfigurer.setLocation(new ClassPathResource(path));
       return propertySourcesPlaceholderConfigurer;
    }
}

我知道了。看起来我不能在同一配置文件中包含JobScoped bean和非JobScoped bean。而且，您不应该在Job bean中使用@JobScope注释。 – Hugo Dias 19小时前
