谷粒商城coupon模块启动报错解决方法之一

        <dependency>
            <groupId>org.hsqldb</groupId>
            <artifactId>hsqldb</artifactId>
            <version>2.5.2</version>
            <scope>runtime</scope>
        </dependency>

 在common模块的pom.xml里添加以上依赖。

我的报错信息是：

Description: Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following:

If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.

If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

我用的是上面加粗这个方法，把nacos嵌入式数据库加到项目类路径即可
