MongoDb问题集

 @Configuration
  public   class   SpringMongoConfig{
 
 
  @Bean
   public   MongoTemplate mongoTemplate()  throws   Exception {
 
      //  remove _class 
    MappingMongoConverter converter = 
         new  MappingMongoConverter(mongoDbFactory(),  new   MongoMappingContext());
    converter.setTypeMapper(  new  DefaultMongoTypeMapper( null  ));
 
    MongoTemplate mongoTemplate  =  new   MongoTemplate(mongoDbFactory(), converter);
 
      return   mongoTemplate;
 
  }
 
} 

二、spring boot 集成mongodb 开启事务

 @Configuration
  public   class   TransactionConfig {

    @Bean
    MongoTransactionManager transactionManager(MongoDbFactory factory){
          return   new   MongoTransactionManager(factory);
    }

}
