  • SpringBoot启动报错Failed to determine a suitable driver class

    SpringBoot启动报错如下

    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
    


    把这个依赖注释掉就好了

    原因

    应用没有使用到DataSource,但是在pom.xml里引入了mybatis-spring-boot-starter

    问题解决办法
    有两种:
    把mybatis-spring-boot-starter的依赖去掉,这样就不会触发spring boot相关的代码
    把spring boot自动初始化DataSource相关的代码禁止掉

    禁止的办法有两种:

    在启动类的@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
