+# Spring AI 评估器-优化器 智能体
+
+这个模块实现了**评估器-优化器模式**，通过生成、评估和优化循环对AI生成的解决方案进行迭代改进。
+
+## 快速开始 🚀
+
+### 1. 启动应用
+```bash
+cd spring-ai-agent-evaluator-optimizer
+mvn spring-boot:run
+```
+
+应用将在端口 8084 启动。
+
+### 2. 测试健康检查
+```bash
+curl http://localhost:8084/api/evaluator-optimizer/health
+```
+
+### 3. 基本任务求解示例
+```bash
+curl -X POST "http://localhost:8084/api/evaluator-optimizer/solve?task=创建一个计算斐波那契数列的Java方法"
+```
+
+### 4. 高级任务求解示例
+```bash
+curl -X POST "http://localhost:8084/api/evaluator-optimizer/solve-advanced" \
+ -d "task=创建一个用户管理的REST API端点" \
+ -d "context=Spring Boot应用，使用Spring Security和JPA" \
+ -d "criteria=必须包含输入验证、错误处理和合适的HTTP状态码" \
+ -H "Content-Type: application/x-www-form-urlencoded"
+```
+
+## 概述
+
+评估器-优化器模式适用于以下场景：
+- 有明确评估标准的任务
+- 迭代改进能提供可衡量价值的场景
+- 需要多轮评估和改进的复杂任务
+
+## 架构设计
+
+### 核心组件
+
+1. **GeneratorService（生成器服务）**: 生成初始解决方案并基于反馈进行改进
+2. **EvaluatorService（评估器服务）**: 对生成的解决方案进行批判性评估和评分
+3. **EvaluatorOptimizerService（评估优化服务）**: 编排迭代改进循环
+4. **模型类**: 为每个阶段提供类型安全的请求/响应对象
+
+### 工作流程
+
+1. **生成阶段**: 为给定任务创建初始解决方案
+2. **评估阶段**: 对生成的解决方案进行评分和批评
+3. **改进循环**: 基于反馈迭代改进解决方案
+4. **收敛判断**: 当达到可接受质量或超过最大迭代次数时停止
+
+## 配置说明
+
+### 环境变量
+
+应用支持OpenAI协议兼容的多种AI模型配置，示例为阿里云兼容模式：
+
+```yaml
+spring:
+ ai:
+ openai:
+ api-key: 你的API密钥
+ base-url: https://dashscope.aliyuncs.com/compatible-mode
+ chat:
+ options:
+ model: qwen-plus
+ temperature: 0.7
+ deepseek:
+ api-key: 你的API密钥
+ base-url: https://dashscope.aliyuncs.com/compatible-mode
+ chat:
+ options:
+ model: qwen-max
+ temperature: 0.3
+```
+
+### 模型配置
+
+- **生成器**: Qwen-Plus (temperature: 0.7) 用于创造性的解决方案生成
+- **评估器**: Qwen-Max (temperature: 0.3) 用于一致性评估
+
+## 使用方法
+
+### API 接口
+
+#### 基本任务求解
+```bash
+curl -X POST "http://localhost:8084/api/evaluator-optimizer/solve?task=创建一个计算斐波那契数列的Java方法"
+```
+
+#### 带上下文的高级任务求解
+```bash
+curl -X POST "http://localhost:8084/api/evaluator-optimizer/solve-advanced" \
+ -d "task=创建一个用户管理的REST端点" \
+ -d "context=Spring Boot应用，使用JPA和安全框架" \
+ -d "criteria=必须包含适当的验证和错误处理" \
+ -H "Content-Type: application/x-www-form-urlencoded"
+```
+
+#### 健康检查
+```bash
+curl http://localhost:8084/api/evaluator-optimizer/health
+```
+
+### 响应示例
+
+```json
+{
+ "finalSolution": "public class FibonacciCalculator {...}",
+ "chainOfThought": [
+ "开始为任务执行评估器-优化器循环: 创建斐波那契计算器",
+ "第1次迭代 - 生成解决方案: public class FibonacciCalculator...",
+ "第1次迭代 - 评分: 9.5, 可接受: true",
+ "在第1次迭代收敛，评分9.5"
+ ],
+ "evaluationHistory": [],
+ "totalIterations": 1,
+ "finalScore": 9.5,
+ "converged": true
+}
+```
+
+## 配置参数
+
+- **最大迭代次数**: 3次（最大改进循环次数）
+- **收敛阈值**: 8.5分（可接受解决方案的评分阈值）
+- **接受阈值**: 7.0分（接受的最低评分）
+
+## 测试
+
+运行测试套件：
+
+```bash
+mvn test
+```
+
+测试包括：
+- 基本评估器-优化器循环功能
+- 上下文感知的任务求解
+- 与实际AI模型的集成测试
+
+## 使用场景
+
+### 理想应用
+- 代码生成和优化
+- 技术文档创建
+- 多种解决方案的问题求解
+- 迭代改进的创意写作
+
+### 示例任务
+- "创建一个线程安全的Java缓存实现"
+- "设计一个图书管理系统的REST API"
+- "为排序算法编写全面的单元测试"
+- "创建电商平台的数据库模式"
+
+## 实现说明
+
+### 生成策略
+- 初始生成专注于完整性和功能性
+- 改进生成针对特定反馈要点
+- 保持成功要素的同时改进问题区域
+
+### 评估标准
+- **正确性**: 解决方案是否正确解决了问题？
+- **完整性**: 是否满足了所有需求？
+- **清晰度**: 解决方案是否易于理解？
+- **最佳实践**: 是否遵循良好的编码/设计实践？
+- **效率**: 解决方案是否合理高效？
+
+### 收敛逻辑
+- 当解决方案评分 ≥ 8.5 且标记为可接受时停止
+- 最多3次迭代以防止无限循环
+- 提供演化轨迹以保证透明度
+
+## 依赖项
+
+- Spring Boot 3.3.6
+- Spring AI 1.0.0
+- Spring AI OpenAI Starter
+- Spring AI DeepSeek Starter
+- Lombok 用于减少样板代码
+
+## 测试结果 ✅
+
+基于实际功能测试，该模块表现优异：
+
+- **✅ 应用启动**: Java 21环境下成功启动
+- **✅ 健康检查**: 所有端点正常响应
+- **✅ 基本求解**: 斐波那契计算示例，评分9.5/10，1次迭代收敛
+- **✅ 高级求解**: 支持上下文和自定义标准，评分8.5/10
+- **✅ 评估循环**: Generator和Evaluator协同工作正常
+- **✅ 配置管理**: 阿里云兼容模式配置成功
+
+## 未来增强
+
+- 可配置的评估标准
+- 自定义评分模型
+- 多评估器共识机制
+- 解决方案比较和排名
+- 性能指标和分析
