在启动springboot时，autowired自动注入报错，
2017-05-26 15:23:05.761 WARN 46372 --- [ main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mongoTest': Unsatisfied dependency expressed through field 'mongoDaoTest'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException)} 2017-05-26 15:23:05.764 INFO 46372 --- [ main] o.apache.catalina.core.StandardService : Stopping service Tomcat 2017-05-26 15:23:05.789 INFO 46372 --- [ main] utoConfigurationReportLoggingInitializer : Error starting ApplicationContext.

会提示注入失败，可以尝试把@EnableAutoConfiguration注解换成@SpringBootApplication;
@SpringBootApplication 注解效果等同于 @Configuration，@EnableAutoConfiguration 及 @ComponentScan 这三个注解一起使用，所以不要在 Controller 上面添加 @EnableAutoConfiguration
