Meta的Spring Batch dataSource

Question

大家好我配置Spring Batch时遇到问题。我有已创建的@Primary dataSource的项目，我无法更改，但我想将批处理元数据保存在单独的内存数据库中，如H2。尝试了与其他帖子不同的东西，但最终仍然在@Primary dataSource中使用了metaData。这是我的示例代码：

@Configuration
@EnableBatchProcessing
public class BatchInfrastructureConfiguration{

@Bean
public TaskScheduler taskScheduler() {
    return new ConcurrentTaskScheduler();
}

@Bean
public PlatformTransactionManager transactionManager(@Qualifier("batchDataSource") DataSource dataSource) {
    return new DataSourceTransactionManager(dataSource);
}

@Bean (name = "batchDataSource")
public DataSource dataSource() {

    EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
    EmbeddedDatabase db = builder
            .setType(EmbeddedDatabaseType.H2)
            .build();
    return db;
 }

@Bean
DefaultBatchConfigurer defaultBatchConfigurer(@Qualifier("batchDataSource") DataSource dataSource){
    return new DefaultBatchConfigurer(dataSource);
 }
}

主要数据源：

@SpringBootApplication
public class ConfigtestApplication {

public static void main(String[] args) {
    SpringApplication.run(ConfigtestApplication.class, args);
}


@Bean
@Primary
public DataSource dataSource() throws ClassNotFoundException {
    SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
    dataSource.setPassword("**");
    dataSource.setUrl("jdbc:mysql://localhost/springbatch");
    dataSource.setUsername("**");
    dataSource.setDriverClass((Class<Driver>) Class.forName("com.mysql.jdbc.Driver"));

    return dataSource;
 }

}
