启用自动配置注解

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@EnableAutoConfiguration(exclude = {RedisAutoConfiguration.class}) //启动自动配置,排除RedisAutoConfiguration
@RestController
public class IndexController {
    @RequestMapping("/")
    public String first(){
        return "hello";
    }
    public static void main(String[] args){
        SpringApplication.run(IndexController.class,args);
    }
}
