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
