java - Spring boot spring.batch.job.enabled=false 无法识别

Question

我在运行 jar 文件时在 application.properties 和 -Dspring.batch.job.enabled=false 中尝试了 spring.batch.job.enabled=false。

但是 @EnableBatchProcessing 在应用程序启动时自动开始运行批处理作业。我如何调试这种情况？

TestConfiguration.class

@Configuration
@EnableBatchProcessing
public class TestConfiguration {...}

主应用程序

@ComponentScan("com.demo")
@EnableAutoConfiguration
public class MainApplication {
public static void main(String[] args) throws BeansException, JobExecutionAlreadyRunningException, JobInstanceAlreadyCompleteException, JobParametersInvalidException, InterruptedException, JobRestartException {

ConfigurableApplicationContext ctx = SpringApplication.run(TestConfiguration.class, args);
...}

pom.xml我将依赖项用作 spring boot 而不是父项

<dependencyManagement>
    <dependencies>
        <!-- Import dependecy for spring boot from here-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>1.2.4.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>

我能够知道发生了什么，我正在使用自定义读取器/处理器/写入器。当 springboot 应用程序启动时，它实际上会尝试对该自定义 beans bean 进行依赖注入(inject)，我已经在其中编写了一些应用程序逻辑。

例子

** TestConfiguration.class**

    @Configuration
    @EnableBatchProcessing
    public class TestConfiguration {

        @Bean
        @Conditional(Employee.class)
        public ItemWriter<Employee> writer_employee(DataSource dataSource) throws IOException {
            FlatFileItemWriter<Employee> writer = new FlatFileItemWriter<Employee>();
            writer.setResource(new FileSystemResource(FinanceReportUtil.createFile("Employee.csv")));
            writer.setHeaderCallback(new FlatFileHeaderCallback() {
                @Override
                    public void writeHeader(Writer writer) throws IOException {
                    writer.write("id, name");
                 }
             });
            DelimitedLineAggregator<Employee> delLineAgg = new DelimitedLineAggregator<Employee>();
            delLineAgg.setDelimiter(",");
            BeanWrapperFieldExtractor<Employee> fieldExtractor = new BeanWrapperFieldExtractor<Employee>();
            fieldExtractor.setNames(new String[]{"id", "name"});
            delLineAgg.setFieldExtractor(fieldExtractor);
            writer.setLineAggregator(delLineAgg);
            return writer;
        }

        @Bean
        @Conditional(Manager.class)
        public ItemWriter<Person> writer_manager(DataSource dataSource) throws IOException {

            // Does the same logic as employee
        }

        // Also has job and step etc.
    }

即使使用 spring.batch.job.enabled=false，它也会创建文件，为了克服这个问题，我创建了自定义逻辑来注入(inject)或不注入(inject) bean，如下所示

application.properties

# all, manager, employee
person=manager

ManagerCondition.class

public class ManagerCondition implements Condition {

@Override
public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
    String person= context.getEnvironment().getProperty("person");
    return person.equals("manager");

}
