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>

注意：参考了以下网址方法，但并不能解决问题。
