+# wx-java-channel-solon-plugin
+
+## 快速开始
+1. 引入依赖
+    ```xml
+    <dependencies>
+        <dependency>
+            <groupId>com.github.binarywang</groupId>
+            <artifactId>wx-java-channel-solon-plugin</artifactId>
+            <version>${version}</version>
+        </dependency>
+   
+        <!-- 配置存储方式为jedis 则引入jedis -->
+        <dependency>
+            <groupId>redis.clients</groupId>
+            <artifactId>jedis</artifactId>
+            <version>${jedis.version}</version>
+        </dependency>
+
+        <!-- 配置存储方式为redisson 则引入redisson -->
+        <dependency>
+            <groupId>org.redisson</groupId>
+            <artifactId>redisson</artifactId>
+            <version>${redisson.version}</version>
+        </dependency>
+    </dependencies>
+    ```
+2. 添加配置(app.properties)
+    ```properties
+    # 视频号配置(必填)
+    ## 视频号小店的appId和secret
+    wx.channel.app-id=@appId
+    wx.channel.secret=@secret
+    # 视频号配置 选填
+    ## 设置视频号小店消息服务器配置的token
+    wx.channel.token=@token
+    ## 设置视频号小店消息服务器配置的EncodingAESKey
+    wx.channel.aes-key=
+    ## 支持JSON或者XML格式，默认JSON
+    wx.channel.msg-data-format=JSON
+    ## 是否使用稳定版 Access Token
+    wx.channel.use-stable-access-token=false
+    
+    
+    # ConfigStorage 配置（选填）
+    ## 配置类型: memory(默认), jedis, redisson, redis_template
+    wx.channel.config-storage.type=memory
+    ## 相关redis前缀配置: wx:channel(默认)
+    wx.channel.config-storage.key-prefix=wx:channel
+    wx.channel.config-storage.redis.host=127.0.0.1
+    wx.channel.config-storage.redis.port=6379
+    wx.channel.config-storage.redis.password=123456
+ 
+    
+    # http 客户端配置（选填）
+    ## # http客户端类型: http_client(默认)
+    wx.channel.config-storage.http-client-type=http_client
+    wx.channel.config-storage.http-proxy-host=
+    wx.channel.config-storage.http-proxy-port=
+    wx.channel.config-storage.http-proxy-username=
+    wx.channel.config-storage.http-proxy-password=
+    ## 最大重试次数，默认：5 次，如果小于 0，则为 0
+    wx.channel.config-storage.max-retry-times=5
+    ## 重试时间间隔步进，默认：1000 毫秒，如果小于 0，则为 1000
+    wx.channel.config-storage.retry-sleep-millis=1000
+    ```
+3. 自动注入的类型
+- `WxChannelService`
+- `WxChannelConfig`
+4. 使用样例
+
+```java
+import me.chanjar.weixin.channel.api.WxChannelService;
+import me.chanjar.weixin.channel.bean.shop.ShopInfoResponse;
+import me.chanjar.weixin.channel.util.JsonUtils;
+import me.chanjar.weixin.common.error.WxErrorException;
+import org.noear.solon.annotation.Inject;
+
+@Component
+public class DemoService {
+  @Inject
+  private WxChannelService wxChannelService;
+
+  public String getShopInfo() throws WxErrorException {
+    // 获取店铺基本信息
+    ShopInfoResponse response = wxChannelService.getBasicService().getShopInfo();
+    // 此处为演示，如果要返回response的结果，建议自己封装一个VO，避免直接返回response
+    return JsonUtils.encode(response);
+  }
+}
+```
