在使Springboot自動(dòng)生成的項(xiàng)目框架時(shí)如果選擇了數(shù)據(jù)源，比如選擇了mysql，生成項(xiàng)目之后，啟動(dòng)會(huì)報(bào)一下異常：

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

導(dǎo)致此問題的原因?yàn)?，springboot生成的項(xiàng)目啟動(dòng)時(shí)會(huì)自動(dòng)注入數(shù)據(jù)源。而此時(shí)在配置文件中并沒有配置數(shù)據(jù)源信息，因此會(huì)拋出異常。

（1）如果暫時(shí)不需要數(shù)據(jù)源，可將pom文件中的mysql和mybatis（或其他數(shù)據(jù)源框架）注釋掉，即可正常啟動(dòng)。

（2）在@SpringBootApplication中排除其注入

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

（3）提供數(shù)據(jù)源的配置或其他數(shù)據(jù)源配置，此處提供默認(rèn)配置示例，在application.properties文件中添加以下配置項(xiàng)：

# 主數(shù)據(jù)源，默認(rèn)的#spring.datasource.type=com.zaxxer.hikari.HikariDataSourcespring.datasource.driverClassName=com.mysql.jdbc.Driverspring.datasource.url=jdbc:mysql://localhost:3306/testspring.datasource.username=rootspring.datasource.password=rootspringboot啟動(dòng)提示缺少數(shù)據(jù)源

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently

因?yàn)閟pring boot只要你在pom中引入了mybatis-spring-boot-starter 他就會(huì)默認(rèn)需要加載數(shù)據(jù)庫相關(guān)的配置

可以加上

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
