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 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).

错误原因

通过查阅资料及分析，发现是因为在pom.xml中引入了jdbc的依赖包，如下：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>5.2.2.RELEASE</version>
</dependency>

但是却没有在spring配置文件中配置数据源的相关信息导致，如下

spring.datasource.driver-class-name =
spring.datasource.url =
spring.datasource.username =
spring.datasource.password =

解决方法

1、第一种方法，也是最简单的方法，如果你的springboot项目不是通spring.jdbc访问数据库，则在pom.xml文件中把spring.jdbc的依赖删除或注释就行，就是把下面的信息在pom.xml中删除注释。

<!--
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>5.2.2.RELEASE</version>
</dependency>
-->

2、第二种方法，就是在application.properties或者application.yml中增加数据源的配置，如下：
application.properties

spring.datasource.driver-class-name =
spring.datasource.url = jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false
spring.datasource.username = root
spring.datasource.password = ******

3、第三种方法，就是在SpringBoot启动类中排除jdbc的自动装配机制即可（如果使用了其他的数据库连接池，比如Druid，则可能会出现问题，不建议使用）

@SpringBootApplication(exclude=DataSourceAutoConfiguration.class)

代码如下：

package com.wongoing;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

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

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