问题描述:
***************************
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 classAction: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
问题分析及解决方案 问题原因:
Mybatis没有找到合适的加载类,其实是大部分spring - datasource -
url没有加载成功,分析原因如下所示.DataSourceAutoConfiguration会自动加载.
没有配置spring - datasource - url 属性.
spring - datasource - url 配置的地址格式有问题.
配置 spring - datasource - url的文件没有加载.
在网上给出了几种解决方案:
方案一 (解决原因1)
排除此类的autoconfig。启动以后就可以正常运行。
@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
很完美没有在报错了:
方案二 (解决原因2)
在application.properties/或者application.yml文件中没有添加数据库配置信息.
spring:datasource:url: jdbc:mysql://localhost:3306/sys?useUnicode=true&characterEncoding=UTF-8&useSSL=falseusername: rootpassword: 123driver-class-name: com.mysql.jdbc.Driver
以上都能解决的问题,我在网络上找的,这两种的话会常用点,所以写上来了。
