一、描述

  設置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中報如下錯誤

  

二、分析

  查看代碼發現，SpringBootApplication中已經包含EnableAutoConfiguration，不需要重復定義

三、解決方法

  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); } }
