错误原因

在pom中引入了mybatis-spring-boot-starter ，Spring boot默认会加载org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration类，DataSourceAutoConfiguration类使用了@Configuration注解向spring注入了dataSource bean。因为工程中没有关于dataSource相关的配置信息，当spring创建dataSource bean因缺少相关的信息就会报错。

解决方案：

在启动类的@EnableAutoConfiguration或@SpringBootApplication中添加exclude = {DataSourceAutoConfiguration.class}，排除此类的autoconfig。
