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。

解决错误
在Spring boot的启动引导类上增加属性@SpringBootApplication(exclude = DataSourceAutoConfiguration.class),即可阻止Spring boot自动注入dataSource
