Attributes should be specified via @SpringBootApplication

一、描述

设置EnableAutoConfiguration，如下

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableAutoConfiguration(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
@EnableScheduling
public class DQServerApplication {

    public static void main(String[] args) {
        System.setProperty("mail.mime.splitlongparameters", "false");
        SpringApplication.run(DQServerApplication.class, args);
    }

}

在idea中报如下错误

二、分析

查看代码发现，SpringBootApplication中已经包含EnableAutoConfiguration，不需要重复定义

三、解决方法

去掉EnableAutoConfiguration即可，如下

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication(exclude = {org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
@EnableScheduling
public class DQServerApplication {

    public static void main(String[] args) {
        System.setProperty("mail.mime.splitlongparameters", "false");
        SpringApplication.run(DQServerApplication.class, args);
    }

}
