在一次新建项目时,启动后报出错误
Consider the following:
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).
研究了一会之后发现,根本原因是我在pom中添加了mybaits,但我的配置文件中又没写数据源,没有配置数据库。
解决方案:
一.pom中把mybaits注释后,刷新pom,可以正常启动
<!-- <dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.2.2</version>
</dependency>-->
二.在yml或properties这类配置文件中,添加数据库datasource参数
spring:
datasource:
# 驱动名称
driver-class-name: com.mysql.cj.jdbc.Driver
# 数据库地址
url: jdbc:mysql://127.0.0.1:3306/demo
# 用户名
username: root
# 密码
password: 123456
三.启动类上添加 exclude={DataSourceAutoConfiguration.class}
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
