第一次用spring boot ，踩了一天的坑，记录一个
Description:
Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-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).
我的报错修改了两个地方，第一是在启动类的@EnableAutoConfiguration或@SpringBootApplication中添加exclude= {DataSourceAutoConfiguration.class}
第二要在pom.xml里的plugins添加
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
