由於我不需要數據庫，啟動springboot報錯：
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).
刪掉pom里全部相關數據庫的jar，也exclude相關DataSource的class，都不能解決，報錯依舊。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 不需要調用數據源解決方法 -->
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>
</dependencies>
注意：參考了以下網址方法，但並不能解決問題。
