## 简介
面向全场景的 Java AI 应用开发框架（支持已知 AI 开发的各种能力）。是 Solon 项目的一部分。也可嵌入到 SpringBoot2、jFinal、Vert.x 等框架中使用。
其中 solon-ai(& mcp) 的嵌入示例：
* https://gitee.com/solonlab/solon-ai-mcp-embedded-examples
* https://gitcode.com/solonlab/solon-ai-mcp-embedded-examples
* https://github.com/solonlab/solon-ai-mcp-embedded-examples
## 主要接口体验示例
* ChatModel（通用接口，基于方言适配实现不同提供商与模型的扩展）
```java
ChatModel chatModel = ChatModel.of("http://127.0.0.1:11434/api/chat")
.provider("ollama") //需要指定供应商，用于识别接口风格（也称为方言）
.model("qwen2.5:1.5b")
.build();
//同步调用，并打印响应消息
System.out.println(chatModel.prompt("hello").call().getMessage());
//响应式调用
chatModel.prompt("hello").stream(); //Publisher<ChatResponse>
```
* Function Calling（或者 Tool Calling）
```java
//可以添加默认工具（即所有请求有产），或请求时工具
chatModel.prompt("今天杭州的天气情况？")
.options(op->op.toolsAdd(new FunctionTools()))
.call();
```
* Vision（多媒体感知）
```java
chatModel.prompt(ChatMessage.ofUser("这图里有方块吗？", Image.ofUrl(imageUrl)))
.call();
```
* RAG（EmbeddingModel，Repository，DocumentLoader，RerankingModel）
```java
//构建知识库
EmbeddingModel embeddingModel = EmbeddingModel.of(apiUrl).apiKey(apiKey).provider(provider).model(model).batchSize(10).build();
RerankingModel rerankingModel = RerankingModel.of(apiUrl).apiKey(apiKey).provider(provider).model(model).build();
InMemoryRepository repository = new InMemoryRepository(TestUtils.getEmbeddingModel()); //3.初始化知识库
repository.insert(new PdfLoader(pdfUri).load());
//检索
List<Document> docs = repository.search(query);
//如果有需要，可以重排一下
docs = rerankingModel.rerank(query, docs);
//提示语增强是
ChatMessage message = ChatMessage.augment(query, docs);
//调用大模型
chatModel.prompt(message)
.call();
```
* Ai Flow（模拟实现 Dify 的流程应用）
```yaml
id: demo1
layout:
- type: "start"
- task: "@VarInput"
meta:
message: "Solon 是谁开发的？"
- task: "@EmbeddingModel"
meta:
embeddingConfig: # "@type": "org.noear.solon.ai.embedding.EmbeddingConfig"
provider: "ollama"
model: "bge-m3"
apiUrl: "http://127.0.0.1:11434/api/embed"
- task: "@InMemoryRepository"
meta:
documentSources:
- "https://solon.noear.org/article/about?format=md"
splitPipeline:
- "org.noear.solon.ai.rag.splitter.RegexTextSplitter"
- "org.noear.solon.ai.rag.splitter.TokenSizeTextSplitter"
- task: "@ChatModel"
meta:
systemPrompt: "你是个知识库"
stream: false
chatConfig: # "@type": "org.noear.solon.ai.chat.ChatConfig"
provider: "ollama"
model: "qwen2.5:1.5b"
apiUrl: "http://127.0.0.1:11434/api/chat"
- task: "@ConsoleOutput"
# FlowEngine flowEngine = FlowEngine.newInstance();
# ...
# flowEngine.eval("demo1");
```
* MCP server（支持多端点）
```java
//组件方式构建
@McpServerEndpoint(name="mcp-case1", sseEndpoint = "/case1/sse")
public class McpServer {
@ToolMapping(description = "查询天气预报")
public String getWeather(@Param(description = "城市位置") String location) {
return "晴，14度";
}
@ResourceMapping(uri = "config://app-version", description = "获取应用版本号", mimeType = "text/config")
public String getAppVersion() {
return "v3.2.0";
}
@PromptMapping(description = "生成关于某个主题的提问")
public Collection<ChatMessage> askQuestion(@Param(description = "主题") String topic) {
return Arrays.asList(
ChatMessage.ofUser("请解释一下'" + topic + "'的概念？")
);
}
}
//原生 java 方式构建
McpServerEndpointProvider serverEndpoint = McpServerEndpointProvider.builder()
.name("mcp-case2")
.sseEndpoint("/case2/sse")
.build();
serverEndpoint.addTool(new MethodToolProvider(new McpServerTools())); //添加工具
serverEndpoint.addResource(new MethodResourceProvider(new McpServerResources())); //添加资源
serverEndpoint.addPrompt(new MethodPromptProvider(new McpServerPrompts())); //添加提示语
serverEndpoint.postStart();
```
* MCP client
```java
McpClientToolProvider clientToolProvider = McpClientToolProvider.builder()
.apiUrl("http://localhost:8080/case1/sse")
.build();
String rst = clientToolProvider.callToolAsText("getWeather", Map.of("location", "杭州"))
.getContent();
```
* MCP Proxy （示例，把 gitee mcp stdio 转为 sse 服务）
配置参考自：https://gitee.com/oschina/mcp-gitee
```java
@McpServerEndpoint(name = "mcp-case3", sseEndpoint="/case3/sse")
public class McpStdioToSseServerDemo implements ToolProvider {
McpClientProvider stdioToolProvider = McpClientProvider.builder()
.channel(McpChannel.STDIO) //表示使用 stdio
.serverParameters(ServerParameters.builder("npx")
.args("-y", "@gitee/mcp-gitee@latest")
.addEnvVar("GITEE_API_BASE", "https://gitee.com/api/v5")
.addEnvVar("GITEE_ACCESS_TOKEN", "<your personal access token>")
.build())
.build();
@Override
public Collection<FunctionTool> getTools() {
return stdioToolProvider.getTools();
}
}
```
