本文主要讲在 mongodb 在分片集群的情况下,springboot如何进行集成。
默认读者熟悉 maven、springboot、mongodb
<!-- mongodb --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-mongodb</artifactId> </dependency>
自定义配置文件,多数据源的
topinfo: mongodb: base: # mongos的地址和端口 uri: mongodb://192.168.90.225:20000,192.168.90.226:20000,192.168.90.227:20000 database: topinfo_base warn: # mongos的地址和端口 uri: mongodb://192.168.90.225:20000,192.168.90.226:20000,192.168.90.227:20000 database: topinfo_warn

以上是 集成的主要配置类, server层直接调用到即可实现。 千万别谢我!!!O(∩_∩)O哈哈~
