springboot整合MongoDb多数据源

1、引入包

   
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
            <version>2.7.3</version>
        </dependency>

2、application.yml 配置文件

 

 

3、封装

package com.sxsoft.config;

import org.springframework.boot.autoconfigure.mongo.MongoProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

 **/
@Configuration
public class MongoDBConfig {

    @Bean(name = "oneMongoProperties")
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.qitamongodbserver")
    public MongoProperties masterMongoProperties() {
        return new MongoProperties();
    }

    @Bean(name = "twoMongoProperties")
    @ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.shuilimongodbserver")
    public MongoProperties twoMongoProperties() {
        return new MongoProperties();
    }

    @Bean(name = "threeMongoProperties")
    @ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.zhujianmongodbserver")
    public MongoProperties threeMongoProperties() {
        return new MongoProperties();
    }
}

3、使用

1、使用默认的db

private MongoTemplate mongoTemplate;//系统默认的mogodb
@Autowired
public void setMongoTemplate(MongoTemplate mongoTemplate){
    this.mongoTemplate = mongoTemplate;
}


2、使用第二个db

private MongoTemplate mongoTemplate;
@Autowired
@Qualifier("twoMongo")
public void setMongoTemplate(MongoTemplate mongoTemplate){
    this.mongoTemplate = mongoTemplate;
}

2、使用第三个db

private MongoTemplate mongoTemplate;
@Autowired
@Qualifier("threeMongo")
public void setMongoTemplate(MongoTemplate mongoTemplate){
    this.mongoTemplate = mongoTemplate;
}
