在 Spring Boot 中调用 AnythingLLM 的发消息接口

 整体逻辑:

自建系统的web UI界面调用接口:

1.SpringBoot接口：/anything/chatMessageAnything

2.调用anythingLLM - 调用知识库+deepseek r1 .

要在 Spring Boot 中调用 AnythingLLM 的发消息接口，可以通过以下步骤实现。假设你已经了解 AnythingLLM 的 API 文档（如端点、认证方式、请求参数等），以下是通用实现方案：

---

1. 添加依赖

在 pom.xml 中添加 Spring Web 依赖（如果项目中没有）：

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

---

2. 配置 AnythingLLM API 参数

在 application.properties 或 application.yml 中配置 API 的基础信息：

properties

# application.properties

anythingllm.api.url=https://api.anythingllm.com/v1/messages

anythingllm.api.key=your_api_key_here

---

3. 创建 API 调用服务

使用 RestTemplate 或 WebClient 调用 AnythingLLM 的接口。以下是两种实现方式：

方式一：使用 RestTemplate

java

import org.springframework.http.HttpEntity;

import org.springframework.http.HttpHeaders;

import org.springframework.http.HttpMethod;

import org.springframework.http.ResponseEntity;

import org.springframework.stereotype.Service;

import org.springframework.web.client.RestTemplate;

@Service

public class AnythingLLMService {

private final RestTemplate restTemplate;

private final String apiUrl;

private final String apiKey;

public AnythingLLMService(

RestTemplate restTemplate,

@Value("${anythingllm.api.url}") String apiUrl,

@Value("${anythingllm.api.key}") String apiKey) {

this.restTemplate = restTemplate;

this.apiUrl = apiUrl;

this.apiKey = apiKey;

}

public ResponseEntity<String> sendMessage(String messageContent) {

// 设置请求头（包含 API Key）

HttpHeaders headers = new HttpHeaders();

headers.set("Authorization", "Bearer " + apiKey);

headers.set("Content-Type", "application/json");

// 构建请求体

String requestBody = "{\"content\": \"" + messageContent + "\"}";

// 发送 POST 请求

HttpEntity<String> request = new HttpEntity<>(requestBody, headers);

return restTemplate.exchange(

apiUrl,

HttpMethod.POST,

request,

String.class

);

}

}

方式二：使用 WebClient（推荐响应式编程）

java

import org.springframework.http.HttpHeaders;

import org.springframework.http.MediaType;

import org.springframework.stereotype.Service;

import org.springframework.web.reactive.function.client.WebClient;

import reactor.core.publisher.Mono;

@Service

public class AnythingLLMService {

private final WebClient webClient;

private final String apiUrl;

private final String apiKey;

public AnythingLLMService(

WebClient.Builder webClientBuilder,

@Value("${anythingllm.api.url}") String apiUrl,

@Value("${anythingllm.api.key}") String apiKey) {

this.webClient = webClientBuilder.baseUrl(apiUrl).build();

this.apiUrl = apiUrl;

this.apiKey = apiKey;

}

public Mono<String> sendMessage(String messageContent) {

return webClient.post()

.uri("/")

.header(HttpHeaders.AUTHORIZATION, "Bearer " + apiKey)

.contentType(MediaType.APPLICATION_JSON)

.bodyValue("{\"content\": \"" + messageContent + "\"}")

.retrieve()

.bodyToMono(String.class);

}

}

---

4. 控制器层（可选）

如果需要通过 HTTP 接口触发消息发送，可以添加一个 Controller：

java

import org.springframework.web.bind.annotation.*;

import reactor.core.publisher.Mono;

@RestController

@RequestMapping("/api/messages")

public class MessageController {

private final AnythingLLMService anythingLLMService;

public MessageController(AnythingLLMService anythingLLMService) {

this.anythingLLMService = anythingLLMService;

}

@PostMapping

public Mono<String> sendMessage(@RequestBody String messageContent) {

return anythingLLMService.sendMessage(messageContent);

}

}

---

5. 异常处理

添加全局异常处理，捕获 API 调用中的错误：

java

import org.springframework.http.HttpStatus;

import org.springframework.http.ResponseEntity;

import org.springframework.web.bind.annotation.ExceptionHandler;

import org.springframework.web.bind.annotation.RestControllerAdvice;

import org.springframework.web.client.HttpClientErrorException;

@RestControllerAdvice

public class GlobalExceptionHandler {

@ExceptionHandler(HttpClientErrorException.class)

public ResponseEntity<String> handleHttpClientError(HttpClientErrorException ex) {

return ResponseEntity.status(ex.getStatusCode())

.body("API调用失败: " + ex.getResponseBodyAsString());

}

}

---

6. 测试调用

使用 RestTemplate 测试

java

@SpringBootTest

public class AnythingLLMServiceTest {

@Autowired

private AnythingLLMService anythingLLMService;

@Test

public void testSendMessage() {

ResponseEntity<String> response = anythingLLMService.sendMessage("Hello, AnythingLLM!");

assertEquals(HttpStatus.OK, response.getStatusCode());

}

}

使用 WebClient 测试

java

@Test

public void testSendMessage() {

anythingLLMService.sendMessage("Hello, AnythingLLM!")

.subscribe(response -> {

assertNotNull(response);

System.out.println("API Response: " + response);

});

}

---

注意事项

1. API 认证 ：根据 AnythingLLM 的文档调整认证方式（如 API Key、OAuth 等）。
2. 请求体格式 ：确保请求体的 JSON 结构与 API 要求一致（如字段名称、嵌套结构）。
3. 超时配置 ：如果接口响应较慢，需配置 RestTemplate 或 WebClient 的超时时间。
4. 日志记录 ：建议在调用过程中添加日志，方便调试和监控。

如果需要更具体的实现（如文件上传、复杂参数），请提供 AnythingLLM 的 API 文档细节！
