集成mongodb

网上都是比较老版本的spring-data-mongodb, 其中mongodb客户端的生成MongoDbFactory接口已经是过时的接口, 新的接口没有在网上找到相关匹配内容。

pom.xml文件引入

 <dependency>
   <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
    <version>2.5.0</version>
 </dependency>

其中配置的mongodb驱动为4.3.2版本

	<dependency>
      <groupId>org.mongodb</groupId>
      <artifactId>mongodb-driver-sync</artifactId>
      <version>4.2.3</version>
      <scope>compile</scope>
    </dependency>

application.properties配置文件

	test.mongodb.uri=mongodb://username:password@ip:port/dbName
	test1.mongodb.uri=mongodb://username:password@ip:port/dbName

mongo配置类生产MongoTemplate

@Configuration
public class MongoConfig {


    @Value("${test.mongodb.uri}")
    private String mongoUri;

    @Value("${test1.mongodb.uri}")
    private String mongoUri1;

    @Bean(name="mongoDatabaseFactory")
    @Primary
    MongoDatabaseFactory mongoDatabaseFactory(){
        return new SimpleMongoClientDatabaseFactory(mongoUri);
    }

    @Bean(name="mongoDatabaseFactory1")
    MongoDatabaseFactory mongoDatabaseFactory1(){
        return new SimpleMongoClientDatabaseFactory(mongoUri1);
    }

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

    @Bean(name = "mongoTemplate1")
    MongoTemplate mongoTemplate1(){
        return new MongoTemplate(mongoDatabaseFactory1());
    }

}

服务调用

@Service
public class MongoService {

    @Autowired
    @Qualifier("mongoTemplate")
    private MongoTemplate mongoTemplate;

    @Autowired
    @Qualifier("mongoTemplate1")
    private MongoTemplate mongoTemplate1;

    public List<Test> findAll(){
        return mongoTemplate.findAll(Test.class);
    }
    public List<Test> findAll1(){
        return mongoTemplate1.findAll(Test.class);
    }
}
