摘要:在使用Spring Boot整合Mongodb的过程中,在做insert对象的时候,在Collection中会出现一个_class字段属性,出现这个问题的原因是在调用mongoTemplate的insert方法时, spring-data-mongodb的TypeConverter会自动给document添加一个_class属性, 值是你保存的类名. 这种设计并没有什么坏处. spring-data-mongodb是为了在把d...
1) Update to the latest version of Spring Data Mongodb My problem was that the latest version of spring-boot-starter-data-mongodb(1.2.6.RELEASE) was using by default an older version of Spring Data MongoDB. In order to use the latest version of Spring Data MongoDB, the easiest way to...

对于很多应用来说,你需要做的就是将正确的Spring Data依赖添加到classpath下(对于JPA有一个spring-boot-starter-data-jpa,对于MongoDB有一个spring-boot-starter-data-mongodb),创建一些repository接口来处理@Entity对象。具体参考JPA sample或Mongodb sample。 Spring Boot会基于它找到的@EnableAutoConfiguration来尝试猜...

Furthermore, the ease with which Spring Boot allows developers to externalize state in NoSQL databases such as Cassandra and MongoDB also helps to simplify the development of stateless microservices. It must be noted that the responsibility to ensure a microservice runs as a stateless process also...
