SpringBoot啟動報錯Failed to determine a suitable driver class怎么辦

小編給大家分享一下SpringBoot啟動報錯Failed to determine a suitable driver class怎么辦，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！

SpringBoot啟動報錯如下

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2019-05-06 21:27:18.275 ERROR 10968 --- [ 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).

Process finished with exit code 1

把這個依賴注釋掉就好了

原因

應用沒有使用到DataSource，但是在pom.xml里引入了mybatis-spring-boot-starter

問題解決辦法

有兩種：

把mybatis-spring-boot-starter的依賴去掉，這樣就不會觸發spring boot相關的代碼

把spring boot自動初始化DataSource相關的代碼禁止掉

禁止的辦法有兩種：

在啟動類的@SpringBootApplication加上

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

在application.properties里配置：

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
