我有一个 Spring 批处理作业，它从数据库读取数据并将其写入 CSV。批处理作业正在尝试使用我正在读取的数据库来保存批处理的状态。我不希望这种事发生。我使用的是 spring 4。
经过广泛的谷歌搜索，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 2:
@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=$$$$$$$$$$
我引用了以下帖子
- https://dzone.com/articles/spring-batch-hello-world-1 Spring-Batch without persisting metadata to database?
- Spring Batch - How to prevent batch from storing transactions in DB
- Spring Boot Batch ResourcelessTransactionManager DataSourceProperties$DataSourceBeanCreationException
我得到的异常如下。虽然这个异常(exception)并不是一个阻碍，但我想摆脱它。

最佳答案
据我所知，禁用元数据持久性是不可能的。无需设置“正确”数据库的一个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，使用 Spring Batch 作业元数据存储库的默认 Spring 数据源存在问题。这里有一个完整的解决方法，可以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(一)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(二)-Spring批量
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);
}
有了这一切，Spring Batch 将使用内存数据源，而您可以出于自己的目的自由使用默认数据源
