springboot-应用无法启动 增加EnableAutoConfiguration-2023-3-31

package com.feijian;

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

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@SpringBootApplication
public class Demo4Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo4Application.class, args);
    }

}

 

或者在 

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).

错误非常明显，因为在spring的pom文件中写入了和数据库有关的依赖，这时候就需要在application.properties文件中进行相关的配置，

或者将相关的依赖进行删除，就可以解决这个问题。

代码如下

spring.datasource.url=jdbc:mysql://localhost:3306/springbootdata?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
