SpringMVC+MongoDB+Maven整合(微信回调Oauth授权)

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

<!--增加mongodb也会自动增加mongojavadriver-->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.2.0.RELEASE</version>
</dependency>
<!--相关驱动-->
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.10.1</version>
</dependency>

WEB.XML配置引入相关xml文件

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml;classpath:mongodb-context.xml</param-value>
</context-param>

SPRING-MVC.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

/**
* Constructor used for a basic template configuration
*
* @param mongo must not be {@literal null}.
* @param databaseName must not be {@literal null} or empty.
*/
public MongoTemplate(Mongo mongo, String databaseName) {
this(new SimpleMongoDbFactory(mongo, databaseName), null);
}

/**
* Constructor used for a template configuration with user credentials in the form of
* {@link org.springframework.data.authentication.UserCredentials}
*
* @param mongo must not be {@literal null}.
* @param databaseName must not be {@literal null} or empty.
* @param userCredentials
*/
public MongoTemplate(Mongo mongo, String databaseName, UserCredentials userCredentials) {
this(new SimpleMongoDbFactory(mongo, databaseName, userCredentials));
}

UserCredentials.java 查看验证传递的参数 username & password

public class UserCredentials {

public static final UserCredentials NO_CREDENTIALS = new UserCredentials(null, null);

private final String username;
private final String password;

/**
* Creates a new {@link UserCredentials} instance from the given username and password. Empty {@link String}s provided
* will be treated like no username or password set.
*
* @param username
* @param password
*/
public UserCredentials(String username, String password) {
this.username = StringUtils.hasText(username) ? username : null;
this.password = StringUtils.hasText(password) ? password : null;
}

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SpringMVC+MongoDB数据库做的微信接入等一些常用接口的DEMO
只实现了回调 和oauth 接口
1. common存放相关基础代码和微信常量
1.1 com/bdxc/plat/common/weixin/WXConstants.java 修改为自己的微信相关的APPID APPSERCET
1.2 com.bdxc.plat.controller存放为请求访问层代码
1.2.1 WXConfigController.java 回调配置需要用到，GET为回调。POST 为用户发送信息进行处理并返回
1.2.2 WXOauthController.java Oauth授权获取用户信息的代码

2. com.bdxc.plat.vo 存放微信相关的接口基础对象

3.com.bdxc.plat.util 存放相关工具类代码包含微信需要用到的
3.1 com.bdxc.plat.util.weixin 存放微信相关工具类

4.com.bdxc.plat.service.weixin 存放微信用户给公众发送信息进行处理的方法， 上一级为操作数据的service 不保存不需要关注

5.com.bdxc.plat.model.weixin 存微信的消息类型的对象，上一级为数据库的model  不保存不需要关注

回调配置代码实现

/**
* 回调配置
* @author 宗潇帅
* @Title WXConfigController
* @时间   2017-1-4上午11:06:05
*/
@Controller
@RequestMapping(value="/wxconfig")
public class WXConfigController {
private static Logger logger = Logger.getLogger(WXConfigController.class);

@RequestMapping(value="/valid",method={RequestMethod.GET},produces = "application/json;charset=UTF-8")
public void valid(HttpServletRequest request,HttpServletResponse response,PrintWriter out) throws Exception{
System.out.println("回调请求=======================");
//微信加密签名
String signature = request.getParameter("signature");
//时间戳
String timestamp = request.getParameter("timestamp");
//随机数
String nonce = request.getParameter("nonce");
//随机字符串
String echostr = request.getParameter("echostr");
out = response.getWriter();
//通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败
if(SignUtil.checkSignature(signature, timestamp, nonce)){
out.print(echostr);
}else{
System.out.println("非微信发送的GET请求");
}
logger.info("回调请求发送的参数为signature"+signature+"\n"+"timestamp"+timestamp+"\n"+"nonce"+nonce+"\n"+"echostr"+echostr);
out.flush();
out.close();
}
@RequestMapping(value="/valid",method={RequestMethod.POST},produces = "application/json;charset=UTF-8")
public void infos(HttpServletRequest request,HttpServletResponse response,PrintWriter out) throws Exception{
/* 消息的接收、处理、响应 */

// 将请求、响应的编码均设置为UTF-8（防止中文乱码）
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
CoreService coreService = new CoreService();
// 调用核心业务类接收消息、处理消息
String respMessage = coreService.processRequest(request);
logger.info(respMessage);
// 响应消息
out = response.getWriter();
out.print(respMessage);
out.close();
}
}

StringUtil代码

/**
*
* 请求校验工具类
*
*/
public class SignUtil {
/**
* 验证签名
*
* @param signature
* @param timestamp
* @param nonce
* @return
*/
public static boolean checkSignature(String signature, String timestamp,
String nonce) {
String[] arr = new String[] {WXConstants.TOKEN, timestamp, nonce };
// 将token、timestamp、nonce三个参数进行字典序排序
Arrays.sort(arr);
StringBuilder content = new StringBuilder();
for (int i = 0; i < arr.length; i++) {
content.append(arr[i]);
}
MessageDigest md = null;
String tmpStr = null;

try {
md = MessageDigest.getInstance("SHA-1");
// 将三个参数字符串拼接成一个字符串进行sha1加密
byte[] digest = md.digest(content.toString().getBytes());
tmpStr = byteToStr(digest);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}

content = null;
// 将sha1加密后的字符串可与signature对比，标识该请求来源于微信
return tmpStr != null ? tmpStr.equals(signature.toUpperCase()) : false;
}
}

Oauth接口，微信授权登录的代码实现

/**
* oauth获取用户信息并保存到mongodb
* @author 宗潇帅

* @时间   2017-1-4上午11:06:14
*/
@Controller
@RequestMapping(value="/wx")
public class WXOauthController {

private static Logger logger = Logger.getLogger(WXOauthController.class);
@Autowired
private WXUserInfoService wxUserInfoService;
/**
* oauth获取用户相关信息
* @param request
* @param response
* @return
* @throws Exception
*/
@RequestMapping(value="/oauth",method={RequestMethod.POST,RequestMethod.GET})
public String oauth(HttpServletRequest request,HttpServletResponse response) throws Exception{
//接受参数
HttpSession httpSession = request.getSession();
String code = request.getParameter("code");
String scope = request.getParameter("scope");
logger.info("==============[OAuthServlet]获取网页授权code="+code);
logger.info("==============[OAuthServlet]获取网页跳转权限="+scope);
if(null != code && !"".equals(code)){
logger.info("==============[OAuthServlet]获取网页授权code不为空，code="+code);
//根据code换取openId
OAuthInfo oa = WeixinUtil.getOAuthOpenId(WXConstants.appId,WXConstants.appSecret,code);
//第一次获取到存到session里面 防止用户刷新页面
if(oa!=null){
httpSession.setAttribute("openid", oa.getOpenId());
}else{
//如果用户是刷新页面。则读取session的openid
Object openid = httpSession.getAttribute("openid");
if(openid!=null){
OAuthInfo authInfo = new OAuthInfo();
String openids = openid.toString();
System.out.println("刷新页面留存的openid"+openids);
authInfo.setOpenId(openids);
oa = authInfo;
}else{
//session也为空 建议用户重新进入页面
//						request.getRequestDispatcher("/warn.jsp").forward(request, response);
return "";
}

}
AccessToken oasign = WXConstants.ACCESS_TOKEN;
WXUserInfo info = WeixinUtil.getWXUserInfo(oasign.getToken(), oa.getOpenId());
if(!"".equals(oa) && null != oa){
logger.info("==============[OAuthServlet]获取网页授权openID="+oa.getOpenId());
//保存信息
try {
wxUserInfoService.insert(info);
request.setAttribute("openid", oa.getOpenId());
request.setAttribute("nickname", info.getNickname());
request.setAttribute("headimgurl", info.getHeadimgurl());
request.setAttribute("city", info.getCity());
request.getRequestDispatcher("/index.jsp").forward(request, response);
return null;
} catch (Exception e) {
e.printStackTrace();
logger.info("保存失败"+e.getMessage());
}
}else{
logger.info("==============[OAuthServlet]获取网页授权openId失败！");
}
}else{
logger.info("==============[OAuthServlet]获取网页授权code失败！");
}
return null;
}
}

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

{
"_id" : ObjectId("586cbbe7150f14811ce04546"),
"_class" : "com.bdxc.plat.model.WXUserInfo",
"subscribe" : 1,
"openid" : "o2VKNju8JqCeGVoEWJ1S8Ue_up8E",
"nickname" : "小帅丶",
"sex" : 1,
"language" : "zh_CN",
"city" : "海淀",
"province" : "北京",
"country" : "中国",
"headimgurl" : "http://wx.qlogo.cn/mmopen/Lj9cibm6LlmjNM8CGSYKuMQiaD4tTPwUjD7zVkkn2u6kFqv4zDwtcfHFntHyxtjjmXeicLDqVqQB42vUukxB5Mia8HgoV94gsN02/0",
"subscribe_time" : "1483520921",
"unionid" : "oUmIot2Yo2Mb_8fVW3UVw9AW1w4Y",
"remark" : "",
"groupid" : 0,
"tagid_list" : []
}

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
