Java Spring Boot和Spring批处理仅创建Jar并运行特定作业

Question

mvn clean package

这是我目前为止根据所有的网上建议所尝试的。

batchConfiguration.java

@Configuration
@EnableBatchProcessing
public class BatchConfiguration {

    private static final Logger logger = LoggerFactory.getLogger(BatchConfiguration.class);

    @Autowired
    public JobBuilderFactory jobBuilderFactory;

    @Autowired
    public StepBuilderFactory stepBuilderFactory;

    @Autowired
    public FileDTO fileDTO;


    @Bean
    public Job fetchJob(Step step) {
        return jobBuilderFactory
                .get("My Job")
                .incrementer(new RunIdIncrementer())
                .flow(step)
                .end()
                .build();
    }

    @Bean
    public Step getData() {
        return stepBuilderFactory
                .get("get data")
                .<FileDTO, FileDTO>chunk(1)
                .reader(FileReader())
                .processor(new FileProcessor())
                .writer(new FileWriter())
                .build();
    }
}

应用程序.属性

spring.datasource.url=jdbc:postgresql://dbhost:1000/db
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.platform=postgresql
spring.batch.job.names=

java -jar target\mytest-0.0.1-SNAPSHOT.jar --spring.batch.job.names=fetchJob

Answer 1

我只是试图在这里建立一个Jar，不想实际运行任何作业。

您不需要添加空属性spring.batch.job.names=，而是需要为此设置属性spring.batch.job.enabled=false。

它根本不会启动作业。

java -jar target\mytest-0.0.1-SNAPSHOT.jar --spring.batch.job.names=fetchJob
