springboot 多数据源（２）使用 Mongorepository

原文：https://blog.csdn.net/qq_35418518/article/details/107411512?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-1.channel_param&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-1.channel_param

依赖：

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

yml :

pring:
  data:
    mongodb:
      primary:
        uri: mongodb://name:passward123@192.168.34.160:27017/test_1?slaveOk=true
      secondary:
        uri: mongodb://name:passward123@192.168.34.160:27017/test_2?slaveOk=true

推荐使用uri ,这样方便添加可选配置　

mongodb://myDBReader:D1fficultP%40ssw0rd@mongodb0.example.com:27017,mongodb1.example.com:27017,mongodb2.example.com:27017/test?replicaSet=myRepl&authSource=admin

如果出现，uri中使用特殊字符。使用16进制进行URL编码代替。（@被使用，%40替换。：被使用，%3A替换）

读取偏好选项

读取首选项描述了与副本集有关的读取操作的行为。 这些参数允许你在连接字符串中基于每个连接指定读取首选项。

• readPreference
• maxStalenessSeconds
• readPreferenceTags

• 连接池选项

  • maxPoolSize
  • minPoolSize
  • maxIdleTimeMS
  • waitQueueMultiple
  • waitQueueTimeoutMS

  • 连接选项

    • ssl
    • connectTimeoutMS
    • socketTimeoutMS
    • compressors
    • zlibCompressionLevel
      
      
      

.目录结构: (不同数据源的使用不同的目录，entity 和repository 置于目录下！！！)

4. game实体类

@Document(collection = "info_account")
@Accessors(chain = true)
@Data
public class AccountInfo {
 
    @Id
    private String account;
 
    private int gameId;
 
    private String passWord;
｝

game repository

public interface AccountRepository extends MongoRepository<AccountInfo,String> {
 
    List<AccountInfo> findAllByAccount(String account);
}

game 数据源配置（每个数据源单独一个配置文件）

@Configuration
@EnableMongoRepositories(basePackages = "com.gray.database.game",
        mongoTemplateRef = "gameDBTemplate")
public class GameDBConfig {
 
    @Bean
    @Primary
    @ConfigurationProperties(prefix="spring.data.mongodb.primary")
    public MongoProperties primaryMongoProperties() {
        return new MongoProperties();
    }
 
    @Primary
    @Bean(name = "gameDBTemplate")
    public MongoTemplate primaryMongoTemplate() throws Exception {
        return new MongoTemplate(primaryFactory(primaryMongoProperties()));
    }
 
    @Bean
    @Primary
    public MongoDbFactory primaryFactory(MongoProperties mongoProperties) throws Exception {
        ConnectionString connectionString = new ConnectionString(mongoProperties.getUri());
        return new SimpleMongoClientDbFactory(connectionString);
    }
}
