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})

/* *   Copyright (c) 2016, inter3i.com. All rights reserved. * *   Author: dq *   Created: 11/18/16 6:01 PM *   Description: * */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

/* *   Copyright (c) 2016, inter3i.com.
