【问题描述】：
当我的 SpringbatchConfiguration 类中配置了数据源时，我能够运行我的 Springbatch 应用程序。但我不想配置数据源。所以我使用了 ResourcelessTransactionManager。请参阅下面我的配置类。有人指导我如何在不将 Datasource 配置为 Batchjob 配置的一部分的情况下启动 Jobs。
@Configuration
@EnableBatchProcessing
@EnableAutoConfiguration
//@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class SprintgBatchConfiguration {
/*@Autowired
private DBConfiguration dbConfig;*/
/*@Autowired
private DataSource dataSource;
@Autowired
private DataSourceTransactionManager transactionManager;
*/
//Tomcat relaated configuration//
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize("124MB");
factory.setMaxRequestSize("124MB");
return factory.createMultipartConfig();
}
@Bean(name="csvjob")
public Job job(JobBuilderFactory jobBuilderFactory,StepBuilderFactory stepBuilderFactory,ItemReader<List<CSVPojo>> itemReader,ItemProcessor<List<CSVPojo>,CsvWrapperPojo> itemProcessor,AmqpItemWriter<CsvWrapperPojo> itemWriter){
Step step=stepBuilderFactory.get("ETL-CSV").<List<CSVPojo>,CsvWrapperPojo>chunk(100)
.reader(itemReader)
.processor(itemProcessor)
.writer(itemWriter)
.build();
Job csvJob= jobBuilderFactory.get("ETL").incrementer(new RunIdIncrementer())
.start(step).build();
return csvJob;
}
@Bean(name="exceljob")
public Job jobExcel(JobBuilderFactory jobBuilderFactory,StepBuilderFactory stepBuilderFactory,ItemReader<List<ExcelPojo>> itemReader,ItemProcessor<List<ExcelPojo>,ExcelWrapperPojo> itemProcessor,AmqpItemWriter<ExcelWrapperPojo> itemWriter){
Step step=stepBuilderFactory.get("ETL-Excel").<List<ExcelPojo>,ExcelWrapperPojo>chunk(100)
.reader(itemReader)
.processor(itemProcessor)
.writer(itemWriter)
.build();
Job ExcelJob= jobBuilderFactory.get("ETL-Excel").incrementer(new RunIdIncrementer())
.start(step).build();
return ExcelJob;
}
/*@Override
public void setDataSource(DataSource dataSource){
System.out.println("overriden");
}*/
/*@Bean
public FlatFileItemReader<CSVPojo> fileItemReader(Resource resource){
return null;
}*/
/*@Bean(name="dataSource")
public DataSource dataSource() throws SQLException
{
//BasicDataSource dataSource = new BasicDataSource();
return dataSource;
}*/
@Bean(name="transactionManager")
public ResourcelessTransactionManager transactionManager() throws SQLException{
return new ResourcelessTransactionManager();
}
/*@Bean(name="transactionManager")
public DataSourceTransactionManager transactionManager() throws SQLException{
DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(this.dataSource());
return transactionManager;
}*/
/*@Bean
public JobRepository jobRepository() throws Exception{
JobRepositoryFactoryBean factoryBean = new JobRepositoryFactoryBean();
factoryBean.setDatabaseType("ORACLE");
factoryBean.setDataSource(dataSource);
factoryBean.setTransactionManager(transactionManager);
factoryBean.setIsolationLevelForCreate("ISOLATION_READ_UNCOMMITTED");
return factoryBean.getObject();
}*/
@Bean
public JobRepository jobRepository(ResourcelessTransactionManager transactionManager) throws Exception {
MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(transactionManager);
mapJobRepositoryFactoryBean.setTransactionManager(transactionManager);
return mapJobRepositoryFactoryBean.getObject();
}
}
但是当我运行应用程序时，我遇到了异常。
ationConfigEmbeddedWebApplicationContext ：在上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为“fileProcessController”的bean时出错：通过字段“jobLauncher”表示不满足的依赖关系；嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为 'org.springframework.batch.core.configuration.annotation.SimpleBatchConfiguration' 的 bean 时出错：通过字段 'dataSources' 表达的不满足依赖关系；嵌套异常是 org.springframework.beans.factory.BeanCreationException：在类路径资源 [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class] 中定义名称为“dataSource”的 bean 创建时出错：通过工厂方法进行 Bean 实例化失败;嵌套异常是 org.springframework.beans.BeanInstantiationException：无法实例化 [org.apache.tomcat.jdbc.pool.DataSource]：工厂方法 'dataSource' 抛出异常；嵌套异常是 org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException：无法确定数据库类型 NONE 的嵌入式数据库驱动程序类。如果您想要一个嵌入式数据库，请在类路径中放置一个受支持的数据库。如果您有要从特定配置文件加载的数据库设置，您可能需要激活它（当前没有配置文件处于活动状态）。
提前致谢！！！！
