由于项目需要访问不通的数据，需要配置两个MongoDB（也可以是多个）

添加依赖

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

配置application.yml或application.properties

spring:  
  data:  
    mongodb:  
      primary:  
        uri: mongodb://user:password@localhost:27017/primarydb  
      secondary:  
        uri: mongodb://user:password@localhost:27018/secondarydb

java配置

启动类排除MongoDB自动配置

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

primary配置类

package XXX;

import com.mongodb.MongoClient;
import com.mongodb.MongoClientOptions;
import org.springframework.beans.factory.ObjectProvider;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.mongo.MongoClientFactory;
import org.springframework.boot.autoconfigure.mongo.MongoProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
