Spring-data-mongodb Criteria类介绍

类 Criteria

• java.lang.Object
• • org.springframework.data.mongodb.core.query.Criteria

• 所有已实现的接口:

  CriteriaDefinition

  直接已知子类:

  GridFsCriteria

  ---

  
  

  public class Criteria
  extends java.lang.Object
  implements CriteriaDefinition

  Central class for creating queries. It follows a fluent API style so that you can easily chain together multiple criteria. Static import of the 'Criteria.where' method will improve readability.
