Sparkdo Specifications

Sparkdo Specifications 是一个实现了规格模式（Specification Pattern）的 .NET 类库。该库提供了一种灵活且可组合的方式来定义业务规则和查询条件。

功能特性

  • 完整的规格模式实现：包括基础规格、组合规格和各种逻辑操作
  • LINQ 表达式支持：所有规格都可以转换为 LINQ 表达式，便于与 Entity Framework 等 ORM 集成
  • 流畅的 API：通过扩展方法提供链式调用语法
  • 高性能：支持表达式组合和参数重绑定，避免常见的 Entity Framework 性能问题

核心组件

基础接口和类

  • ISpecification<T>：规格的基础接口
  • Specification<T>：规格的抽象基类
  • ExpressionSpecification<T>：从 LINQ 表达式创建的规格
  • AnySpecification<T>：始终返回 true 的规格
  • NoneSpecification<T>：始终返回 false 的规格

组合规格

  • AndSpecification<T>：AND 组合规格
  • OrSpecification<T>：OR 组合规格
  • NotSpecification<T>：NOT 规格（反转）
  • AndNotSpecification<T>：AND NOT 组合规格

辅助类

  • SpecificationBuilder：创建规格的便捷方法
  • SpecificationExtensions：规格的扩展方法
  • ExpressionFuncExtender：表达式扩展方法

使用示例

基础用法

// 创建一个简单的规格
var spec = new ExpressionSpecification<Person>(p => p.Age >= 18);

// 检查对象是否满足规格
bool isSatisfied = spec.IsSatisfiedBy(person);

组合规格

// 创建多个规格
var ageSpec = new ExpressionSpecification<Person>(p => p.Age >= 18);
var nameSpec = new ExpressionSpecification<Person>(p => p.Name.StartsWith("A"));

// 组合规格
var combinedSpec = ageSpec.And(nameSpec);

使用 SpecificationBuilder

// 使用便捷方法创建规格
var spec = SpecificationBuilder.PropertyEquals<Person, int>(p => p.Age, 25);

转换为 LINQ 表达式

// 将规格转换为 LINQ 表达式，用于 Entity Framework 查询
var expression = spec.ToExpression();
var adults = context.People.Where(expression);

扩展方法

该库提供了丰富的扩展方法，支持链式调用：

  • And()：AND 组合
  • Or()：OR 组合
  • AndNot()：AND NOT 组合
  • Not()：NOT 操作（反转）
