本文档描述了在启动SpringBoot应用时遇到的数据源配置错误，由于缺少数据库URL导致应用无法正常启动。解决方案包括在启动类中排除数据源自动配置或在配置文件中提供完整的数据源信息。此外，还提供了POM文件中可能引起问题的依赖项示例，并给出了排除问题的步骤。

1、Springboot启动报错信息

在使用springboot的时候创建项目的时候会出现下面的情况

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2021-05-06 18:10:59.279 ERROR 18620 --- [           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).

2021-05-06 18:10:59.288 ERROR 18620 --- [           main] o.s.test.context.TestContextManager      : Caught exception while allowing TestExecutionListener [org.springframework.test.context.web.ServletTestExecutionListener@8f2ef19] to prepare test instance [com.zkr.fieldssynchronizationprocess.FieldsSynchronizationProcessApplicationTests@6b0615ae]

java.lang.IllegalStateException: Failed to load ApplicationContext

这种情况的发生多半就是你在POM中引入了WEB、MySQL、MyBatis造成的

 <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
 <dependency>
     <groupId>mysql</groupId>
     <artifactId>mysql-connector-java</artifactId>
     <scope>runtime</scope>
 </dependency>
 <dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.4</version>
 </dependency>

1.1解决办法

1、在启动类注解上加入排除检验数据库合法校验规则（排除即可）

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

2、在application.yml中进行配置数据源信息完成校验。
