Spring boot 數(shù)據(jù)源未配置異常的解決
在使Springboot自動生成的項目框架時如果選擇了數(shù)據(jù)源,比如選擇了mysql,生成項目之后,啟動會報一下異常:
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).
問題分析導致此問題的原因為,springboot生成的項目啟動時會自動注入數(shù)據(jù)源。而此時在配置文件中并沒有配置數(shù)據(jù)源信息,因此會拋出異常。
解決方案(1)如果暫時不需要數(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。
(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,此處提供默認配置示例,在application.properties文件中添加以下配置項:
# 主數(shù)據(jù)源,默認的#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
正解:因為spring boot只要你在pom中引入了mybatis-spring-boot-starter 他就會默認需要加載數(shù)據(jù)庫相關的配置
可以加上
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
以上為個人經(jīng)驗,希望能給大家一個參考,也希望大家多多支持好吧啦網(wǎng)。
