Springboot雙mongodb配置方式
更新時間:2024年05月29日 14:50:14 作者:竇再興
這篇文章主要介紹了Springboot雙mongodb配置方式,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教
準備工作
- 本地mongodb一個
- 創(chuàng)建兩個數(shù)據(jù)庫 student 和 student-two
所需jar包
# springboot基于的版本 <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.1.RELEASE</version> <relativePath/> </parent> # maven 關鍵jar包 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-mongodb</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency>
配置文件
# uri 配置樣例: mongodb://myDBReader:DifficultPassword@mongodb0.example.com:27017/admin # 如果用戶名或密碼包含at符號@,冒號:,斜杠/或百分號%字符,請使用百分比編碼方式消除歧義 # uri 集群配置樣例: mongodb://myDBReader:D1fficultP%40ssw0rd@mongodb0.example.com:27017,mongodb1.example.com:27017,mongodb2.example.com:27017/admin?replicaSet=myRepl douzi: mongo: primary: uri: mongodb://127.0.0.1:27017/student repository-package: com.douzi.mongo.dao.primary secondary: uri: mongodb://127.0.0.1:27017/student-two repository-package: com.douzi.mongo.dao.secondary
多數(shù)據(jù)源配置類 MultipleMongoConfig
package com.douzi.mongo.config; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import org.springframework.data.mongodb.MongoDbFactory; import org.springframework.data.mongodb.core.MongoTemplate; import org.springframework.data.mongodb.core.SimpleMongoDbFactory; import org.springframework.util.StringUtils; import com.mongodb.MongoClientURI; /** * @Author douzi * @Title: MultipleMongoConfig * @Description: 讀取對應的配置信息并且構造對應的MongoTemplate * @Date 2023-09-27 */ @Configuration public class MultipleMongoConfig { @Value("${douzi.mongo.primary.uri}") private String primaryUri; @Value("${douzi.mongo.secondary.uri}") private String secondaryUri; /** * 配置主數(shù)據(jù)源template * @return 主數(shù)據(jù)源template */ @Primary @Bean(name = PrimaryMongoConfig.MONGO_TEMPLATE) public MongoTemplate primaryMongoTemplate() { return new MongoTemplate(primaryFactory()); } /** * 配置從數(shù)據(jù)源template * @return 從數(shù)據(jù)源template */ @Bean @Qualifier(SecondaryMongoConfig.MONGO_TEMPLATE) public MongoTemplate secondaryMongoTemplate() { return new MongoTemplate(secondaryFactory()); } /** * 配置主數(shù)據(jù)源db工廠 * @param mongo 屬性配置信息 * @return 主數(shù)據(jù)源db工廠 */ @Bean @Primary public MongoDbFactory primaryFactory() { if (StringUtils.isEmpty(primaryUri)) { throw new RuntimeException("必須配置mongo primary Uri"); } return new SimpleMongoDbFactory(new MongoClientURI(primaryUri)); } /** * 配置從數(shù)據(jù)源db工廠 * @param mongo 屬性配置信息 * @return 從數(shù)據(jù)源db工廠 */ @Bean public MongoDbFactory secondaryFactory() { return new SimpleMongoDbFactory(new MongoClientURI(secondaryUri)); } }
主數(shù)據(jù)源配置 PrimaryMongoConfig
package com.douzi.mongo.config; import org.springframework.context.annotation.Configuration; import org.springframework.data.mongodb.repository.config.EnableMongoRepositories; /** * @Author douzi * @Title: PrimaryMongoConfig * @Description: 主數(shù)據(jù)源配置 * @date 2023-09-27 */ @Configuration @EnableMongoRepositories(basePackages = "${douzi.mongo.primary.repository-package}", mongoTemplateRef = PrimaryMongoConfig.MONGO_TEMPLATE) public class PrimaryMongoConfig { protected static final String MONGO_TEMPLATE = "primaryMongoTemplate"; }
副數(shù)據(jù)源配置 SecondaryMongoConfig
package com.douzi.mongo.config; import org.springframework.context.annotation.Configuration; import org.springframework.data.mongodb.repository.config.EnableMongoRepositories; /** * @Author douzi * @Title: SecondaryMongoConfig * @Description: 從數(shù)據(jù)源配置 * @Date 2023-09-27 */ @Configuration @EnableMongoRepositories(basePackages = "${douzi.mongo.secondary.repository-package}", mongoTemplateRef = SecondaryMongoConfig.MONGO_TEMPLATE) public class SecondaryMongoConfig { protected static final String MONGO_TEMPLATE = "secondaryMongoTemplate"; }
