 注意还要在启动类上加@ServletComponentScan注解

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

@ServletComponentScan
@SpringBootApplication
public class WebLogRunMainApplication {
	public static void main(String[] args) {
        SpringApplication.run(WebLogRunMainApplication.class, args);
    }
}
