為了將程式運行在JDK1.6的環境
做了Spring Boot降版2.1.4->1.2.1
程式完全沒動只有改POM.XML而已
pom.xml:

<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
<!-- 		<version>2.1.4.RELEASE</version> -->
			<version>1.2.1.RELEASE</version> 
		<relativePath /> <!-- lookup parent from repository -->
	</parent>

@ComponentScan
@SpringBootApplication
@EnableBatchProcessing
@EnableScheduling
@EnableRetry
public  class BatchApplication {
  @Autowired
  JobLauncher jobLauncher;
	@Value("${batch.runOnce}")
  boolean runOnce;
  @Autowired
  Job processJob;
	public static void main(String[] args) {
		SpringApplication.run(BatchApplication.class, args);
	}
// @Scheduled(cron = "${cron.expression}")  
  @Scheduled(fixedDelayString = "${fixedDelayString.expression}")
	public void perform() throws Exception {
      JobParameters jobParameters = new JobParametersBuilder()
      		.addLong("time", System.currentTimeMillis())
              .toJobParameters();
      jobLauncher.run(processJob, jobParameters);
		if(runOnce) {
			System.exit(0);
		}
  }
}

降版前原本的程式可以正常WORK
但降了版本出現這樣的EXCEPTION:
Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.springframework.batch.core.launch.JobLauncher com.foya.BatchApplication.jobLauncher;
詳細如下

是什麼原因呢?
