配置MongoDB,编写MongoDBConfig配置

mongodb:
  uri: mongodb://appdb:appdb@node01:28017/appdb
  database: appdb
  authentication-database: appdb
  userName: appdb
  password: appdb
  host: node01
  port: 28017

配置MongoClient

@Configuration
public class MongoConfig {

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

    @Value("${mongodb.database}")
    private String database;

    @Value("${mongodb.authentication-database}")
    private String authenticationDataBase;

    @Value("${mongodb.userName}")
    private String userName;

    @Value("${mongodb.password}")
    private String password;

    @Value("${mongodb.port}")
    private Integer port;

    @Value("${mongodb.host}")
    private String host;

    @Bean
    public MongoClient mongoClient() {
//        MongoClientSettings.Builder builder = MongoClientSettings.builder();
//        MongoCredential credential = MongoCredential.createCredential(userName,authenticationDataBase,password.toCharArray());
//        builder.credential(credential);
//        builder.applyConnectionString(new ConnectionString(uri));
//        return MongoClients.create(builder.build(), SpringDataMongoDB.driverInformation());
        return MongoClients.create(uri);
    }

}

配置MongoTemplate

@Bean
public MongoTemplate mongoTemplate() {
    MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());
    return mongoTemplate;
}

@Bean
public MongoDatabaseFactory mongoDbFactory() {
   return new SimpleMongoClientDatabaseFactory(mongoClient(),database);
}

配置MongoDB事务

@Bean
public MongoTransactionManager mongoTransactionManager(MongoDatabaseFactory mongoDbFactory) {
    return new MongoTransactionManager(mongoDbFactory);
}

如果是spring boot集成MongoDB的话，就不需要配置上面的MongoTemplate的了，如果想要开启事务需要配置下 MongoTransactionManager

spring boot集成mongo只需要在配置文件中配置：

spring:
  data:
    mongodb:
      uri: mongodb://appdb:appdb@node01:28017/appdb
      authentication-database: appdb

或者：

spring:
  data:
    mongodb:
      username: appdb
      password: appdb
      authentication-database: appdb
      host: node01
      port: 28017
      database: appdb
