dede企业网站模板下载如何做外贸业务
1、当我们使用大模型问
请告诉我现在北京时间几点了
回答如下
此时就需要大模型的 function call 的功能，也就是 给大模型加上工具
2、代码如下
获取时间的工具类
package com.alibaba.cloud.ai.example.chat.ollama.tools.time;import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;/*** @author yingzi* @date 2025/3/27:10:56*/
public class TimeUtils {public static String getTimeByZoneId(String zoneId) {// Get the time zone using ZoneIdZoneId zid = ZoneId.of(zoneId);// Get the current time in this time zoneZonedDateTime zonedDateTime = ZonedDateTime.now(zid);// Defining a formatterDateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss z");// Format ZonedDateTime as a stringString formattedDateTime = zonedDateTime.format(formatter);return formattedDateTime;}
}
获取时间的工具
package com.alibaba.cloud.ai.example.chat.ollama.tools.time.method;import com.alibaba.cloud.ai.example.chat.ollama.tools.time.TimeUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.ai.tool.annotation.Tool;
import org.springframework.ai.tool.annotation.ToolParam;public class TimeTools {private static final Logger logger = LoggerFactory.getLogger(TimeTools.class);@Tool(description = "Get the time of a specified city.")public String getCityTimeMethod(@ToolParam(description = "Time zone id, such as Asia/Shanghai") String timeZoneId) {logger.info("The current time zone is {}", timeZoneId);return String.format("The current time zone is %s and the current time is " + "%s", timeZoneId,TimeUtils.getTimeByZoneId(timeZoneId));}
}
controller代码如下
package com.alibaba.cloud.ai.example.chat.ollama.controller;import com.alibaba.cloud.ai.example.chat.ollama.tools.time.method.TimeTools;
import org.springframework.ai.chat.client.ChatClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/time")
public class TimeController {private final ChatClient ollamaiChatClient;public TimeController(ChatClient.Builder chatClientBuilder) {this.ollamaiChatClient = chatClientBuilder.build();}/*** 无工具版*/@GetMapping("/chat")public String simpleChat(@RequestParam(value = "query", defaultValue = "请告诉我现在北京时间几点了") String query) {return ollamaiChatClient.prompt(query).call().content();}/*** 调用工具版 - function*/@GetMapping("/chat-tool-function")public String chatTranslateFunction(@RequestParam(value = "query", defaultValue = "请告诉我现在北京时间几点了") String query) {return ollamaiChatClient.prompt(query).tools("getCityTimeFunction").call().content();}/*** 调用工具版 - method*/@GetMapping("/chat-tool-method")public String chatTranslateMethod(@RequestParam(value = "query", defaultValue = "请告诉我现在北京时间几点了") String query) {return ollamaiChatClient.prompt(query).tools(new TimeTools()).call().content();}}
