在进行springboot和mybatis遇到了这个错误

Servlet.service() for servlet [dispatcherServlet] in context with path [] th

解决点：仔细检查配置是不是正确

1.主程序有没有扫描到包

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception_spring

 2.检查@autowired

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception_spring_02

3.接口检查：有没有标注上@service和@Mapper

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception_spring_03
