我的架构演化笔记 5：增加发表博客功能

表弟：“博客分类已经有了，现在总可以来发表博客吧”

我“恩，没问题”

~~~~~~~~~~~~~

package controllers.project0.v1;

		if (login == false) {
			return badRequest("{\"result\":\"fail\",\"desc\":\"please login firstly!\"}");
		}

		// 获取数据，插入到blog里去
		JsonNode body = request().body().asJson();

		MongoClient con = MongoConnectionPool.getConnection();

执行：

至于索引，暂时就不添加了，等后续有查询需求再添加，大功告成。
