类 QueryModel<T extends QueryModel<T>>

java.lang.Object

com.mybatisflex.core.activerecord.query.QueryModel<T>

类型参数:

T - 实体类类型

直接已知子类:

Model

public abstract class QueryModel<T extends QueryModel<T>>
extends Object

实体类条件查询构建模型。

该类内部维护了一个 QueryWrapper 属性，用来构建查询条件。 通过实体类属性构建的查询条件都是值等于，该扩展用于非等于值构建，及一些其他方法。 如果不想通过实体类直接构建查询条件，可以不继承该类。
