Question

我正在编写一个Spring批处理应用程序，我将Oracle用作数据存储。当运行构建和spring加载时，它正在寻找hsqldb，尽管我已将ORACLE定义为databaseType。以下是日志中的错误：无法加载JDBC驱动程序类org.hsqldb.jdbcDriver

我不想使用单独的数据库来存储spring批量元数据。请告知为什么春季批量寻找hsqldb。

 <bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
    <property name="transactionManager" ref="transactionManager"/>
    <property name="dataSource" ref="paymentDataSource"/>
    <property name="databaseType" value="ORACLE" />
 </bean>

您是否已在application.properties中定义了相应的属性？

例如：

spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

Oracle JAR在pom.xml中的依赖性？

为什么春季批量寻找hsqldb
