消费者怎么创建与使用？
确认和保证投递，有没有封装？
文档有点太简单。。。。

当前只提供了channel(),其他木有

欢迎提交你的实现哦

我能直接提交么？要不要开个号给我？

什么叫开个号??? https://github.com/nutzam/nutzmore

测试报空指针异常。。。我配置错误？没能正常注入？

自行new出来的对象，不死才怪

依然不全, 放在入口方法里面测, 别放在jsp里面

找到问题了，是缺了 slf4jd的jar包

这里面还需要增加 rabbitmq.js 么？ 配置文件没生效，一直链接 localhost

你应该定义conf这个bean了吧?? 在它的扫描路径内添加rabbitmq.properties

rabbitmq.host=你需要的ip/域名
