在使用springboot创建新项目后，在启动服务之后报如下错误：

解决办法：
检查启动类是否加上如下注解：
@MapperScan(basePackages = {"com.xx.xx.mapper"}, markerInterface = BaseMapper.class) @ComponentScan(basePackages = {"com.xx.xx"}) @SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
2. 检查service的实现类上是否加上了注解 @Service
3. 检查mapper接口类上面是否加了注解：@Mapper
4. 检查pom.xml文件是否有添加了mybatis相关的依赖包，要注意版本兼容问题，同时在pom.xml文件的<build></build>添加如下配置，来保证文件都能正常被扫描到并且加载成功：
<resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> <include>**/*.json</include> </includes> <filtering>true</filtering> </resource> </resources>
5. 检查application.properties文件中是否配置了数据库的相关连接信息以及mybatis相关的配置
mybatis.type-aliases-package=com.xx.xx.entity.** mybatis.mapper-locations=classpath:mapper/*.xml #mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
如果以上几个步奏都没法解决重启报这个错误的话，那一定是jar包的版本有问题，可以试着降低版本，然后重新加载maven依赖，编译之后重新在试试。
