我有一个从数据库读取并写入CSV的Spring批处理作业。批处理作业正在尝试使用我正在从中读取的数据库来保存批处理的状态。我不希望这种情况发生。我正在使用Spring 4。
经过广泛的谷歌搜索后，我尝试了两种方法，但都失败了。
方法1：
@Bean public JobLauncher jobLauncher() { SimpleJobLauncher simpleJobLauncher = new SimpleJobLauncher(); simpleJobLauncher.setJobRepository(jobRepository()); simpleJobLauncher.setTaskExecutor(taskExecutor()); return simpleJobLauncher; } @Bean public JobRepository jobRepository() { SimpleJobRepository simpleJobRepository = new SimpleJobRepository(new MapJobInstanceDao(), new MapJobExecutionDao(), new MapStepExecutionDao(), new MapExecutionContextDao()); return simpleJobRepository; } @Bean public SimpleJob simpleJob() { SimpleJob simpleJob = new SimpleJob(); simpleJob.setName("Feedback surevey job"); List<Step> steps = new ArrayList<>(1); steps.add(step1()); simpleJob.setSteps(steps); simpleJob.setJobRepository(jobRepository()); return simpleJob; } @Bean public TaskExecutor taskExecutor(){ SimpleAsyncTaskExecutor asyncTaskExecutor=new SimpleAsyncTaskExecutor("spring_batch"); asyncTaskExecutor.setConcurrencyLimit(this.threadCount); return asyncTaskExecutor; } @Bean public Step step1() { return stepBuilderFactory.get("step1").<Feedback, Feedback> chunk(chuckSize) .reader(reader()) .writer(writer()) .taskExecutor(taskExecutor()) .throttleLimit(this.threadCount).build(); }
方法二：
@Bean public Job importUserJob(JobCompletionNotificationListener listener) { return jobBuilderFactory.get("importUserJob") .incrementer(new RunIdIncrementer()).listener(listener) .flow(step1()).end().build(); } @Bean public ResourcelessTransactionManager transactionManager() { return new ResourcelessTransactionManager(); } @Bean public JobRepository jobRepository(ResourcelessTransactionManager transactionManager) throws Exception { MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(transactionManager); mapJobRepositoryFactoryBean.setTransactionManager(transactionManager); return mapJobRepositoryFactoryBean.getObject(); } @Bean public Step step1() { return stepBuilderFactory.get("step1").<Feedback, Feedback> chunk(chuckSize) .reader(reader()) .writer(writer()) .taskExecutor(taskExecutor()) .throttleLimit(this.threadCount).build(); }
application.properties中的相关部分：
spring.datasource.url=###### spring.datasource.username=************ spring.datasource.password=$$$$$$$$$$
我得到的异常如下。尽管例外不是演出停止，但我想摆脱它。

据我所知，不可能禁用元数据持久性。不必设置“适当”数据库的一种可能的解决方法是使用内存数据库来存储元数据：
pom.xml
<dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> </dependency>
但是，存在将默认Spring数据源用于Spring Batch Jobs元数据存储库的问题。这里有一个完整的解决方法，以便为其定义辅助数据源：
application.properties
################################### ### JOBS DATASOURCE PROPERTIES. ### ################################### ## URL used to connect to the jobs database. spring.secondDatasource.url=jdbc:h2:mem:jobsdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE ## Driver class used to connect to the jobs database (it will depend on datasource). spring.secondDatasource.driver-class-Name=org.h2.Driver ## User name spring.secondDatasource.username=xxx ## Password spring.secondDatasource.password=xxx ## Datasource configuration for jobs database. spring.jpa.hibernate.ddl-auto=create-drop spring.secondDatasource.initialize=true spring.secondDatasource.test-on-borrow=true spring.secondDatasource.validation-query=select 1
Spring配置（I）数据源
/** * Config class holding several datasources, one business related, other for the spring batch jobs */ @Configuration public class DataSourceConfiguration { @Bean @Qualifier("businessDataSource") @ConfigurationProperties(prefix = "spring.datasource") public DataSource primaryDataSource() { return DataSourceBuilder.create().build(); } @Bean @Primary @Qualifier("jobsDataSource") @ConfigurationProperties(prefix = "spring.secondDatasource") public DataSource secondaryDataSource() { return DataSourceBuilder.create().build(); } }
spring配置（II）-spring批处理
import org.springframework.batch.core.configuration.annotation.DefaultBatchConfigurer; // Another @Configuration class... @Autowired @Qualifier("jobsDataSource") private DataSource dataSource; @Bean public BatchConfigurer configurer() { // This is required to avoid problems when jobs datasource is into some secondary datasource. return new DefaultBatchConfigurer(dataSource); }
有了这些，Spring Batch将使用内存中的数据源，而您可以自由使用默认数据源来实现自己的目的
