个人小程序。里面是基于百度大脑 腾讯优图做的人脸检测。是关于人工智能的哦。
2017年第一篇自己在工作中的总结文档。土豪可以打赏哦。
https://git.oschina.net/xshuai/smplat.git 项目在GIT上面了。这里就是源代码地址。麻烦看仔细点
- 项目简述：
使用SpringMVC+Maven搭建，整合MongoDB。入门级整理总结，不足之处多多理解。
- 项目结构：
- XML相关配置
POM.XML
注意： SpringMVC使用的版本4.0.5 其他版本的请自行测试

SPRING-MVC.XML
注意： SpringMVC配置仅供参考哦

MONGODB-CONTEXT.XML

- 相关的java内容，看源代码的构造和api可以有很大帮助哦
MongoTemplate.java可以看到有2个构造方法这样就根据自己的MongoDB是否有验证进行xml配置
1 /** 2 * Constructor used for a basic template configuration 3 * 4 * @param mongo must not be {@literal null}. 5 * @param databaseName must not be {@literal null} or empty. 6 */ 7 public MongoTemplate(Mongo mongo, String databaseName) { 8 this(new SimpleMongoDbFactory(mongo, databaseName), null); 9 } 10 11 /** 12 * Constructor used for a template configuration with user credentials in the form of 13 * {@link org.springframework.data.authentication.UserCredentials} 14 * 15 * @param mongo must not be {@literal null}. 16 * @param databaseName must not be {@literal null} or empty. 17 * @param userCredentials 18 */ 19 public MongoTemplate(Mongo mongo, String databaseName, UserCredentials userCredentials) { 20 this(new SimpleMongoDbFactory(mongo, databaseName, userCredentials)); 21 }
UserCredentials.java 查看验证传递的参数 username & password
1public class UserCredentials { 2 3 public static final UserCredentials NO_CREDENTIALS = new UserCredentials(null, null); 4 5 private final String username; 6 private final String password; 7 8 /** 9 * Creates a new {@link UserCredentials} instance from the given username and password. Empty {@link String}s provided 10 * will be treated like no username or password set. 11 * 12 * @param username 13 * @param password 14 */ 15 public UserCredentials(String username, String password) { 16 this.username = StringUtils.hasText(username) ? username : null; 17 this.password = StringUtils.hasText(password) ? password : null; 18 }
整合MongoDB的内容就这些。后续会将整个代码及项目上传git，访问路径会在此博文更新
以下内容是小测试。
基于该框架写了一个微信的回调和授权(Oauth),SpringMVC+MongoDB+Maven搭建微信后台框架，包含了回调配置和授权Oauth配置 项目结构在最上面有截图哦。

基于mongodb做了一个测试，授权登录的用户进行将相关信息保存。简单实现没有做任何封装。使用的是MongoTemplate这个类进行的增删改查。
测试号关注超过100人就会有问题。因此我全部移除了，想看效果的重新关注测试号，demo的框架换成了上面使用的SpringMVC+MongoDB+Maven整合(微信回调Oauth授权)，因此有些菜单点击会有错误哦。
第一访问会提示确认登录的相关信息。确认登录后就是右边显示的相关内容哦。
确认登录后获取到openid，那就可以拿到用户的相关信息了。存在了mongodb数据库
mongodb是documents 非关系型数据库。保存的都是以文本 大家可以理解为json字符串
得到的数据如下面代码显示。id是mongodb生成的唯一id
1{ 2 "_id" : ObjectId("586cbbe7150f14811ce04546"), 3 "_class" : "com.bdxc.plat.model.WXUserInfo", 4 "subscribe" : 1, 5 "openid" : "o2VKNju8JqCeGVoEWJ1S8Ue_up8E", 6 "nickname" : "小帅丶", 7 "sex" : 1, 8 "language" : "zh_CN", 9 "city" : "海淀", 10 "province" : "北京", 11 "country" : "中国", 12 "headimgurl" : "http://wx.qlogo.cn/mmopen/Lj9cibm6LlmjNM8CGSYKuMQiaD4tTPwUjD7zVkkn2u6kFqv4zDwtcfHFntHyxtjjmXeicLDqVqQB42vUukxB5Mia8HgoV94gsN02/0", 13 "subscribe_time" : "1483520921", 14 "unionid" : "oUmIot2Yo2Mb_8fVW3UVw9AW1w4Y", 15 "remark" : "", 16 "groupid" : 0, 17 "tagid_list" : [] 18}
本文主要是说mongodb验证用户名和密码的xml的配置内容。顺便博主拿微信写了个demo。后续完善后会上传git。目前有servlet的版本在众包提供服务哦。https://zb.oschina.net/service/f9918c2f1e643513
