Spring Boot spring.batch.job.enabled = false无法识别 [英] Spring boot spring.batch.job.enabled=false not able to recognize
问题描述
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
.
I tried spring.batch.job.enabled=false
in application.properties and -Dspring.batch.job.enabled=false
when running the jar file.
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?
However @EnableBatchProcessing
automatically start running the batch jobs on application start. How i can debug such scenario?
TestConfiguration.class
@Configuration
@EnableBatchProcessing
public class TestConfiguration {...}
MainApplication
@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 我使用依赖项作为Spring Boot而不是父项
pom.xml I am using dependency as spring boot and not as parent
<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>
推荐答案
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,实际上尝试在我编写了一些应用程序逻辑的地方对此自定义bean进行依赖项注入.
I was able to know whats going on, I am using custom reader/processor/writer. When springboot application starts it actually try to do dependency injection of this custom beans beans where I have written some application logic.
示例
** TestConfiguration.class **
** 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,它也将创建文件,为了克服这一点,我创建了自定义逻辑来注入或不注入bean,如下所示:
It will create the file even with spring.batch.job.enabled=false, to overcome this I have created custom logic to inject the beans or not as below
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");
}
