多数据源配置(MongoDB)

Mongo配置文件：

spring:            
  data:
    mongodb:
      #xd ubuntu
      one:
        uri: mongodb://192.168.3.180:27017/data
      #xd Windows
      two:
        uri: mongodb://192.168.3.180:27017/data2

Mongo one配置类

import com.mongodb.client.MongoClients;
import org.springframework.context.EnvironmentAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;


@Configuration
@EnableMongoRepositories(mongoTemplateRef = "oneMongo")
public  class MongoOneConfig implements EnvironmentAware {

    private Environment environment;

    @Override
    public void setEnvironment(final Environment environment) {
        this.environment = environment;
    }

    @Bean(name = "oneMongo")
    @Primary
    public MongoTemplate mongoTemplate() {
        return new MongoTemplate(mongoDatabaseFactory());
    }

    @Bean(name = "oneMongoFactory")
    @Primary
    public MongoDatabaseFactory mongoDatabaseFactory() {
        MongoClient client = MongoClients.create(environment.getProperty("spring.data.mongodb.one.uri"));
        return new SimpleMongoClientDatabaseFactory(client, "data");
    }
}

Mongo two配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;

    private Environment environment;
    @Override
    public void setEnvironment(final Environment environment) {
        this.environment = environment;
    }

    @Bean(name = "twoMongo")
    public MongoTemplate mongoTemplate() {
        return new MongoTemplate(mongoDatabaseFactory());
    }

    @Bean(name = "twoMongoFactory")
    public MongoDatabaseFactory mongoDatabaseFactory() {
        MongoClient client = MongoClients.create(environment.getProperty("spring.data.mongodb.two.uri"));
        return new SimpleMongoClientDatabaseFactory(client, "data2");
    }
}

调用Mongo

    @Autowired
    @Qualifier("oneMongo")
    private MongoTemplate oneMongoTemplate;
    @Autowired
    @Qualifier("twoMongo")
    private MongoTemplate twoMongoTemplate;
