ArticleContentController获取逛的详情内容

+# ArticleContentController获取逛的详情内容 #
+**方法：getArticleContent()**
+
+**请求参数**
+    <table>
+       <tr><th>参数名称</th><th>参数类型</th><th>可否为空</th><th>示例</th><th>默认值</th><th>备注</th></tr>
+       <tr><td>article\_id</td><td>string</td><td>否</td><td>5</td><td>0</td><td>文章id</td></tr>
+       <tr><td>client\_type</td><td>string</td><td>否</td><td>h5</td><td>h5</td><td>客户端类型</td></tr>
+    </table>
+**实现逻辑：**
+
+1、ArticleContentController.getArticleContent()方法中调用sns.guang.getArticleContent服务；
+
+2、对参数article\_id文章id是否为空或是否小于0进行验证，若为空则抛出文章id不能为空的异常或文章id错误异常；对参数client\_type进行是否为空验证，若为空则设为默认值"h5";
+
+3、根据article\_id查询数据库表article\_block获取该文章id对应的blocks信息，包括详情内容信息和内容键值等信息;
+
+4、对blocks对象进行转换，返回封装的ArticleContentRspBO对象；
+
+**示例**
+请求：http://localhost:8080/gateway/guang/service/*/article/getArticleContent?article_id=5&client_type=h5&debug=XYZ
