2018-06-23 01:48:05.275 INFO 7104 — [ main] o.apache.catalina.core.StandardService : Stopping service [Tomcat]

Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug’ enabled.
2018-06-23 01:48:05.358 ERROR 7104 — [ main] o.s.b.d.LoggingFailureAnalysisReporter :

APPLICATION FAILED TO START

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).
复制代码
这是因为添加了数据库组件，所以autoconfig会去读取数据源配置，而新建的项目还没有配置数据源，所以会导致异常出现。

解决办法：

去掉数据库依赖
2.在启动类的@EnableAutoConfiguration或@SpringBootApplication中添加exclude = {DataSourceAutoConfiguration.class}，排除此类的autoconfig。启动以后就可以正常运行。

复制代码
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class BdservoApplication {
public static void main(String[] args) {
SpringApplication.run(BdservoApplication.class, args);
}
}
