mongodb - Spring Boot连接到Mongo容器运行的MongoDB副本集

Question

我设置了2个mongo容器，其端口为27017:27017和27018:27017。 mongo1设置为主，mongo2设置次要，并使用副本集。

mongo1作为主要对象同时具有写，读访问权限，而mongo2仅具有读访问权限

spring.data.mongodb.uri = mongodb://abc.xyz:27017/user_demo   
//monog1, abc.xyz is the hostname

spring.data.mongodb.uri = mongodb://abc.xyz:27018/user_demo   
//mongo2

如果我在正常的Spring Boot程序中仅连接monogo1，则它可以工作(读，写)，如果我设置mongo2则可以工作(仅读)，但是当我在一行中同时设置这两个时，它将出错

spring.data.mongodb.uri = mongodb://abc.xyz:27017,abc.xyz:27018/user_demo?replicaSet=idea-mongo-set

我通过存储在mongo1中来检查副本集是否正常工作，在mongo2中我可以读取

因此，最后一行出了什么问题。还有其他方法可以为副本集存储uri

在官方 spring site中给出

spring.data.mongodb.uri=mongodb://user:secret@mongo1.example.com:12345,mongo2.example.com:23456/test

我得到的错误是

Answer 1

您的uri似乎在连接副本集的正确轨道上。

spring.data.mongodb.uri = mongodb://abc.xyz:27017,abc.xyz:27018/user_demo?replicaSet=idea-mongo-set

此处省略凭据(用户，密码)只是错字吗？

这是我们用于副本集连接uri的确切语法:

mongodb://user:pwd@server1:27017,server2:27017,server3:27017/our_collection?replicaSet=replica_set_name&authSource=authagainstthiscollection&authMechanism=SCRAM-SHA-1
