Springboot集成MongoDB(MongoTemplate)

1、依赖包

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>

2、配置

# MongoDB 单机
#spring.data.mongodb.uri=mongodb://lt_dms_test:1j23W1tLBZ21eoCZ@10.123.4.41:27001/dms_test
# MongoDB 集群
spring.data.mongodb.uri=mongodb://lt_dms_test:1j23W1tLBZ21eoCZ@ops-mongodb-test01.shein.com:27001,ops-mongodb-test02.shein.com:27001,ops-mongodb-test03.shein.com:27001/dms_test
