之前研究过《springBoot mybatis 多数据源 下划线转驼峰》,这次再来看看spring boot mongodb 多数据源 自动下划线转驼峰。
一般数据库的字段我们都习惯用下划线，java代码里面习惯使用驼峰，将下划线自动映射驼峰字段效率很高。
1.mongodb单个数据源下划线转驼峰
spring.data.mongodb.uri=mongodb://192.168.1.191:29000,192.168.1.192:29000,192.168.1.193:29000/database
spring.data.mongodb.field-naming-strategy=org.springframework.data.mapping.model.SnakeCaseFieldNamingStrategy
2.mongodb多数据下划线转驼峰配置
@Configuration
public class EcgMongodbDatasource {
@Primary
@Bean(name = "ecgMongodbProperties")
@ConfigurationProperties(prefix="spring.data.mongodb.testmongodb")
public MongoProperties ecgMongodbProperties() {
return new MongoProperties();
}
@Primary
@Bean(name = "ecgMongodbTemplate")
public MongoTemplate ecgMongodbTemplate(){
MongoDbFactory mongoDbFactory=new SimpleMongoClientDbFactory(ecgMongodbProperties().getUri());
DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDbFactory);
MongoMappingContext mongoMappingContext=new MongoMappingContext();
//下划线转驼峰
mongoMappingContext.setFieldNamingStrategy(new SnakeCaseFieldNamingStrategy());
MongoConverter mongoConverter = new MappingMongoConverter(dbRefResolver,mongoMappingContext);
return new MongoTemplate(mongoDbFactory,mongoConverter);
}
}
