從restcontroller運行一個簡單的spring批處理

[英]run a simple spring batch from restcontroller

 原文  2017-01-27 14:42:02  3   1    java/ spring/ spring-mvc/ spring-batch

問題描述

當我運行spring boot應用程序時，該批處理無需實例化JobLauncher即可完美運行，我認為是由於@EnableBatchProcessing批注，但是當我輸入特定的URL來通過實例化JobLauncher並從中啟動初始作業在restController中啟動同一批處理時它失敗的上下文，這是代碼： 

@RestController
@Import(BatchConfiguration.class)
@EnableBatchProcessing
public class BatchController {
    @Autowired
    JobLauncher jobLauncher;
    @RequestMapping("/run")
    public void runBatch() {
        System.out.println("starting the job..........");
        ApplicationContext context = new AnnotationConfigApplicationContext(
                "src/main/resources/batchjob.xml");
        Job job = (Job) context.getBean("job");
        try {
            JobParameters jobParameters = new JobParametersBuilder().addLong(
                    "time", System.currentTimeMillis()).toJobParameters();
            jobLauncher.run(job, jobParameters);
        } catch (JobExecutionAlreadyRunningException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JobRestartException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JobInstanceAlreadyCompleteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (JobParametersInvalidException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("finishing the job..........");
    }
}

===> BatchConfiguration.class： 

@Configuration
@ImportResource("classpath:batchjob.xml")
@EnableBatchProcessing
public class BatchConfiguration {

    @Bean
    public Job job(JobBuilderFactory jobBuilderFactory, Step step1) {
        return jobBuilderFactory.get("job").incrementer(new RunIdIncrementer())
                .flow(step1).end().build();
    }

    @Bean
    public Step step1(StepBuilderFactory stepBuilderFactory) {
        return stepBuilderFactory.get("step1").<Person, Person> chunk(10)
                .reader(new PersonItemReader())
                .processor(new PersonItemProcessor())
                .writer(new PersonItemWriter()).build();
    }
}

===> batchjob.xml： 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                </batch:chunk>
            </batch:tasklet>
        </batch:step>

    </batch:job>

    <bean id="itemReader" class="com.example.chunk.PersonItemReader"></bean>
    <bean id="itemProcessor"
        class="com.example.chunk.PersonItemProcessor">
    </bean>
    <bean id="itemWriter" class="com.example.chunk.PersonItemWriter"></bean>


</beans>

===> BatchConfigApplication： 

@SpringBootApplication
public class BatchConfigApplication {

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

在此處輸入圖片說明

===>這是錯誤：

代替 ： 

 @ImportResource("classpath:batchjob.xml")  
 public class BatchConfiguration {
 ....
 }

嘗試這個： 

@ImportResource({
  "classpath:WEB-INF/spring/batchjob.xml",
  "classpath:WEB-INF/spring/applicationContext.xml"
})
public class BatchConfiguration {
 ....
}
