java - 如何使用 Spring Data 删除 MongoDB 中的记录

Question

我想在Spring中根据Id删除一条记录。 但在数据库中id值是对象 例如:-

id: Object(34562341112313)

如何在Spring中删除这条记录？

Answer 1

你确实喜欢这样:

public void deleteRecord() {
    MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
    Query searchQuery = new Query(Criteria.where("id").is(34562341112313));
    mongoOperation.remove(searchQuery, Your_entity_class.class);
    logger.info("Delete success");
}

这是我的现实例子:

/**
 * Delete by condition(s).
 */
public void deleteJob() {
    MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
    Query searchQuery = new Query(Criteria.where("company").is("DCV"));
    mongoOperation.remove(searchQuery, Job.class);
    logger.info("Đã xóa các công việc đăng bởi DCV.");
}
