我正在尝试运行一个Spring Batch应用程序，该应用程序从SQL Server DB中读取数据并写入csv文件。下面是SQL Server DB的DatabaseConfiguration文件：-

@Configuration
@EnableTransactionmanagement
@EnableJpaRepositories(
        basePackages = {"com.sample.repository"},entityManagerFactoryRef = "sampleEntityManagerFactory",transactionmanagerRef = "transManager"
)
public class Compensationconfiguration
{
    @Primary
    @Bean(name="cmpnDS")
    @ConfigurationProperties(prefix = "sample.datasource.compensation")
    public DataSource sampleDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Primary
    @Bean(name = "sampleEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean sampleEntityManagerFactory(EntityManagerFactoryBuilder builder,@Qualifier("cmpnDS") DataSource dataSource) {
        return builder
                .dataSource(dataSource)
                .packages("com.opencodez.entity")
                .build();
    }

    @Primary
    @Bean(name = "transManager")
    public PlatformTransactionmanager hrprdTransactionmanager(@Qualifier("sampleEntityManagerFactory")
                                                                      EntityManagerFactory entityManagerFactoryBean) {
        return new JpaTransactionmanager(entityManagerFactoryBean);
    }
}

以下是pom文件中的摘录：-

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.1.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<version>0.0.1-snAPSHOT</version>
<packaging>jar</packaging>

<description>Demo project for Spring Boot</description>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

    <maven-jar-plugin.version>2.6</maven-jar-plugin.version>

</properties>
<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <scope>runtime</scope>
</dependency>

以及属性文件中的以下内容：-

spring:
  datasource:
    url: jdbc:h2:mem:testdb
    username: sa
    password:
    driver-class-name: org.h2.Driver

当我尝试启动应用程序时，无法启动并显示以下错误：-

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'h2Console' defined in class path resource [org/springframework/boot/autoconfigure/h2/H2ConsoleAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.web.servlet.ServletRegistrationBean]: Factory method 'h2Console' threw exception; nested exception is java.lang.IllegalArgumentException: dataSource or dataSourceclassname or jdbcUrl is required.

此应用程序读取SQL Server数据库以处理记录。弹簧批处理在内存DB H2Database中使用。这是多数据源方案吗？我没有对H2的数据源配置进行任何编码，因为它应该是自动配置的。我在pom中包含了所有必需的依赖项-sprign-batch-core，devtools，h2数据库，jpa等。
