Spring引导无法在jar中自动装配bean，并在加载时导致错误。

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.xxx.xxx.core.orm.XXXSqlTemplate] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我的Starter课程是

@SpringBootApplication
@EnableAutoConfiguration
@EnableWebMvc
@ComponentScan("com.sds")
@Configuration
public class Starter {

    public static void main(String[] args) {
        SpringApplication.run(Starter.class, args);
    }

}

com.xxx.xxx.core.orm.XXXSqlTemplate类位于jar中，jar也包含在类路径中。

我该如何解决这个问题？我将tomcat更改为jetty作为嵌入式servlet容器。但是没有解决方法。

如果SqlTemplate类不在com.sds的子包中，则必须将类的包（或其超级包）添加到ComponentScan注释中，如下所示：

@ComponentScan({"com.sds", "com.xxx"})
