新建了一個springboot項目報一下錯誤：

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

原因是加入了mybaties依賴而沒有指定數據庫url屬性，解決方式：

1、去除mybaties依賴，即去除

<dependency>
    <groupId>org.mybatis.spring.boot</
 
groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.0.0</version>
</dependency>

2、加入數據庫相關的配置，即加上

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&zeroDateTimeBehavior
 
=convertToNull&allowMultiQueries=true&useSSL=false
    username: xxx
    password: xxx

3、在啟動類的@EnableAutoConfiguration或@SpringBootApplication中添加exclude = {DataSourceAutoConfiguration.class}，排除此類的autoconfig。即

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)  
public
 
 class YourApplication {  

    public static void main(String[] args) {  
        SpringApplication.run(YourApplication.class, args);  
    }  
}

啟動以後就可以正常運行。

springboot啟動報錯 Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
