我试图在centos 7中启动rabbitmq服务器.我安装了erlang,因为它是对rabbitmq-server的依赖.包erlang.x86_64 0:R16B-03.7.el7.然后使用package rabbitmq-server-3.2.2-1.noarch.rpm安装rabbitmq.安装成功.我启用了管理控制台uisng rabbitmq-plugins启用rabbitmq_management.但是在启动服务rabbitmq-server时失败了.
[root@tve-centos ~]# systemctl start rabbitmq-server.service
Job for rabbitmq-server.service failed. See 'systemctl status rabbitmq-server.service' and 'journalctl -xn' for details.
[root@tve-centos ~]# systemctl status rabbitmq-server.service

Sep 12 …我在我的java应用程序中使用spring数据mongodb框架来将我的应用程序数据保存在mongodb中.在我的java模型类中,我有两个字段.
1)一个带有@Id注释的字段.2)字段ID
关于映射到保存的mongodb文档中的_id键,哪一个会得到偏好,或者我会得到多个映射的错误.我正在使用spring data mongo 1.6.1.我知道我可以测试一下,但我没有本地环境设置.
