本文详细介绍如何在Spring Boot项目中配置并使用两个MongoDB数据库，通过@Autowired和@Resource注解实现MongoTemplate实例的注入，以及如何指定不同的MongoDB连接URI。

package com.bjsdzk.collector.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.env.Environment;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.SimpleMongoDbFactory;

import com.mongodb.MongoClientURI;

@Configuration
public class MongoConfig {

	@Autowired
	private Environment env;
	 @Value("${spring.data.mongodb.uri}")
     private String MONGO_URI;
	
    @Primary
    @Bean(name="mongoTemplate")
    public MongoTemplate getMongoTemplate(MongoClientOptions mongoOptions) {
    	MongoClientURI mongoClientURI = new MongoClientURI(MONGO_URI,MongoClientOptions.builder(mongoOptions));
    	return new MongoTemplate(new SimpleMongoDbFactory(mongoClientURI));
    }
    
    @Bean(name="secondMongoTemplate")
    public MongoTemplate getMongoTemplate2() {
    	MongoClientURI mongoClientURI = new MongoClientURI(env.getProperty("spring.data.mongodb.secondary.uri"));
        return new MongoTemplate(new SimpleMongoDbFactory(mongoClientURI));
    }
    
}

	@Resource(name="secondMongoTemplate")
    private MongoTemplate secondMongoTemplate;
	@Autowired
    private MongoTemplate mongoTemplate;

spring.data.mongodb.secondary.uri=************

spring.data.mongodb.uri=mongodb://192.168.1.154:27017/sdzk-data

@Autowired如果类型找不到会按名字找，第二个只能用@Resource注解了
