SpringBoot use AnnotationConfigWebApplicationContext

`package code;

import b.BController; import lombok.extern.slf4j.Slf4j; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration; import org.springframework.boot.context.properties.ConfigurationPropertiesScan; import org.springframework.context.ApplicationContext; import org.springframework.context.ConfigurableApplicationContext; import org.springframework.scheduling.annotation.EnableAsync; import org.springframework.scheduling.annotation.EnableScheduling; import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;

    subContext.setParent(parentContext);
    subContext.register(BController.class);
    subContext.refresh();
    return subContext;
}

} `

`package b;

import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;

}

@RequestMapping("/hello")
public String hello() {
    return "hello world";
}

} `

使用AnnotationConfigWebApplicationContext 子容器希望通过 http://localhost:18801/hello 能访问路由
