springboot 禁用mongoDB自动配置
一、问题背景
springboot 内置了mongoDB驱动，默认配置localhost：27017，若本机没有配置mongoDB，则会连接失败。
二、解决方案
1. 添加注解：@SpringBootApplication(exclude = {MongoAutoConfiguration.class,MongoDataAutoConfiguration.class})

package com.inter3i.sun.api.ota.v1;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration;
import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
@ComponentScan
@SpringBootApplication(exclude = {MongoAutoConfiguration.class,MongoDataAutoConfiguration.class})
//在部署到外部的Tomcat时，需要将classpath的引入文件去掉，因为在web.xml已经配置过一次了
//@ImportResource("classpath:dispatcher-servlet.xml")
public class Application{
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}2. 走过的弯路：这样配置，使用Spring Boot 内置的tomcat没有任何问题，但是一旦将war包部署至服务器，spring boot还是会去实例化一个默认的mongoDB
@EnableAutoConfiguration(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@EnableConfigurationProperties/*
