mybatis+postgresql+jpa搭建项目
使用RestTemplate调用API
1.报错：
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled. 2020-12-28 22:55:14.693 ERROR 5072 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter : *************************** APPLICATION FAILED TO START *************************** 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).
2.问题代码
3，解决方法，
方案1：在启动类的注解加上exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class}
方案2：在pom文件中加入database的包
4.原因：
spring boot默认会加载
org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
类，DataSourceAutoConfiguration类使用了@Configuration注解向spring注入了dataSource bean。因为工程中没有关于dataSource相关的配置信息，当spring创建dataSource bean因缺少相关的信息就会报错
