报错Cannot determine embedded database driver class for database type NONE解决方法

由于我不需要数据库，启动springboot报错：

Cannot determine embedded database driver class for database type NONE
If you want an embedded database please put a supported one on the classpath.
If you have database settings to be loaded from a particular profile
you may need to active it (no profiles are currently active).

删掉pom里全部相关数据库的jar，也exclude相关DataSource的class，都不能解决，报错依旧。最后：

pom增加：

    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
    </dependency>

完整的：

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
        <!-- Cannot determine embedded database driver class for database type 
            NONE 不需要调用数据源解决方法 -->
        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
        </dependency>
    </dependencies>
