SpringBoot整合微信登录
1.准备工作
1.1 获取微信登录凭证
前往官网微信开放平台 (qq.com)，完成以下步骤：
- 注册
- 邮箱激活
- 完善开发者资料
- 开发者资质认证
- 创建网站应用
1.2 配置文件
在配置文件application.properties添加相关配置信息：
# 微信开放平台 appid
wx.open.app_id=你的appid
# 微信开放平台 appsecret
wx.open.app_secret=你的appsecret
# 微信开放平台重定向url
wx.open.redirect_url=http://81/api/ucenter/wx/callback
1.3 添加依赖
<!--httpclient-->
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
</dependency>
<!--commons-io-->
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
</dependency>
<!--gson-->
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</dependency>
1.4 创建读取公共常量的工具类
创建读取公共常量的工具类ConstantWxUtils：
/**
* @author xppll
* @date 2021/12/11 14:39
*/
@Component
public class ConstantWxUtils implements InitializingBean
@Value("$wx.open.app_id")
private String appId;
@Value("$wx.open.app_secret")
private String appSecret;
@Value("$wx.open.redirect_url")
private String redirectUrl;
public static String WX_OPEN_APP_ID;
public static String WX_OPEN_APP_SECRET;
public static String WX_OPEN_REDIRECT_URL;
@Override
public void afterPropertiesSet() throws Exception
WX_OPEN_APP_ID = appId;
WX_OPEN_APP_SECRET = appSecret;
WX_OPEN_REDIRECT_URL = redirectUrl;
1.5 HttpClient工具类
/**
