**标题:** SpringBoot整合WxJava实现短key托管（短链接管理）

**内容:**

在微信公众平台中，短key托管是指将长的URL转换为短的URL，以便于用户分享和访问。这种技术可以减少URL长度，提高分享的易用性。SpringBoot整合WxJava可以实现短key托管功能。

**第一步：添加依赖**

在pom.xml文件中添加以下依赖：

xml<dependency>
 <groupId>com.github.wxjava</groupId>
 <artifactId>wx-java-sdk</artifactId>
 <version>1.0.2</version>
</dependency>

propertieswx.appid=你的appidwx.secret=你的secret

javaimport com.github.wxjava.core.WxJava;
import org.springframework.stereotype.Service;

@Servicepublic class ShortKeyService {

 @Value("${wx.appid}")
 private String appId;

 @Value("${wx.secret}")
 private String secret;

 public String getShortKey(String longUrl) {
 // 使用WxJava生成短key WxJava wx = new WxJava(appId, secret);
 String shortKey = wx.getShortKey(longUrl);
 return shortKey;
 }
}

javaimport org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Servicepublic class ShortLinkManager {

 @Autowired private ShortKeyService shortKeyService;

 public String getLongUrl(String shortKey) {
 // 使用WxJava获取长URL WxJava wx = new WxJava(shortKeyService.getAppId(), shortKeyService.getSecret());
 String longUrl = wx.getLongUrl(shortKey);
 return longUrl;
 }
}

java@RestControllerpublic class TestController {

 @Autowired private ShortLinkManager shortLinkManager;

 @GetMapping("/short-key")
 public String getShortKey() {
 //生成长URL String longUrl = " /> // 获取短key String shortKey = shortLinkManager.getShortKey(longUrl);
 return shortKey;
 }

 @GetMapping("/long-url")
 public String getLongUrl() {
 // 获取短key String shortKey = "your_short_key";
 // 获取长URL String longUrl = shortLinkManager.getLongUrl(shortKey);
 return longUrl;
 }
}
