我目前正在处理来自spring文档的spring hello示例。因为他们正在连接嵌入式数据库，而我正在尝试配置mysql数据库。 来自git https://github.com/spring-guides/gs-batch-processing.git
的样本请指导我一步。
将jdbc-driver添加到pom.xml

这是数据库配置文件

</beans>
我在这里遗漏了什么？但仍然连接到嵌入式hsql db。见下文，

试试这个。我使用以下属性连接到Mysql。我可以看到你使用的那些属性可能适用于postgresql。
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/spring" />
<property name="username" value="root" />
<property name="password" value="" />
</bean>
如果不起作用，请告诉我。
