java.lang.IllegalStateException: Cannot load driver class: org.h2.Driver

SpringBoot启动项目时：Cannot load driver class: org.h2.Driver

报错场景：引入的三方依赖本身依赖数据源spring-boot-starter-jdbc，spring-boot-starter-data-jpa，希望启动不需要数据库的项目，且未在application.yml（或properties）中配置数据源，pom.xml中引入相关数据源依赖。

错误一：

解决方案：在启动类注解@SpringBootApplication后增加exclude = {DruidDataSourceAutoConfigure.class} 

@SpringBootApplication(exclude = {DruidDataSourceAutoConfigure.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

解决方案：在启动类注解@SpringBootApplication后增加exclude = {DataSourceAutoConfiguration.class} 

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

两种情况都排除 

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, DruidDataSourceAutoConfigure.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

配置后启动成功：
