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); } }
