2.8 服务层实现
BaiduMapService.java
package com.example.service;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.example.config.BaiduMapProperties;
import com.example.dto.request.GeocodingRequest;
import com.example.dto.request.ReverseGeocodingRequest;
import com.example.dto.response.GeocodingResult;
import com.example.dto.response.ReverseGeocodingResult;
import lombok.extern.slf4j.Slf4j;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.util.EntityUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
@Slf4j
@Service
public class BaiduMapService {
@Autowired
private CloseableHttpClient httpClient;
@Autowired
private BaiduMapProperties baiduMapProperties;
/**
* 地理编码(地址转坐标)
*/
public GeocodingResult geocoding(GeocodingRequest request) {
try {
URIBuilder uriBuilder = new URIBuilder(baiduMapProperties.getGeocodingUrl());
uriBuilder.setParameter("address", request.getAddress())
.setParameter("output", "json")
.setParameter("ak", baiduMapProperties.getAk())
.setParameter("ret_coordtype", String.valueOf(request.getRetCoordtype()));
if (StringUtils.hasText(request.getCity())) {
uriBuilder.setParameter("city", request.getCity());
}
URI uri = uriBuilder.build();
String response = executeGet(uri);
JSONObject jsonObject = JSON.parseObject(response);
if (jsonObject.getInteger("status") == 0) {
JSONObject result = jsonObject.getJSONObject("result");
return JSON.parseObject(result.toJSONString(), GeocodingResult.class);
} else {
log.error("地理编码失败: {}", jsonObject.getString("message"));
return null;
}
} catch (URISyntaxException e) {
log.error("URI构建异常", e);
return null;
}
}
/**
* 逆地理编码(坐标转地址)
*/
public ReverseGeocodingResult reverseGeocoding(ReverseGeocodingRequest request) {
try {
URIBuilder uriBuilder = new URIBuilder(baiduMapProperties.getReverseGeocodingUrl());
String location = request.getLatitude() + "," + request.getLongitude();
uriBuilder.setParameter("location", location)
.setParameter("output", "json")
.setParameter("ak", baiduMapProperties.getAk())
.setParameter("ret_coordtype", String.valueOf(request.getRetCoordtype()))
.setParameter("radius", String.valueOf(request.getRadius()))
.setParameter("extensions_poi", "1"); // 返回周边POI
URI uri = uriBuilder.build();
String response = executeGet(uri);
JSONObject jsonObject = JSON.parseObject(response);
if (jsonObject.getInteger("status") == 0) {
JSONObject result = jsonObject.getJSONObject("result");
return JSON.parseObject(result.toJSONString(), ReverseGeocodingResult.class);
} else {
log.error("逆地理编码失败: {}", jsonObject.getString("message"));
return null;
}
} catch (URISyntaxException e) {
log.error("URI构建异常", e);
return null;
}
}
/**
* 执行HTTP GET请求
*/
private String executeGet(URI uri) {
HttpGet httpGet = new HttpGet(uri);
httpGet.setHeader("Content-Type", "application/json;charset=utf-8");
try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
return EntityUtils.toString(response.getEntity(), "UTF-8");
} catch (IOException e) {
log.error("HTTP请求异常", e);
return null;
}
}
}
2.9 控制器层实现
BaiduMapController.java
package com.example.controller;
import com.example.dto.BaseResponse;
import com.example.dto.request.GeocodingRequest;
import com.example.dto.request.ReverseGeocodingRequest;
import com.example.dto.response.GeocodingResult;
import com.example.dto.response.ReverseGeocodingResult;
import com.example.service.BaiduMapService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
@Slf4j
@RestController
@RequestMapping("/api/map")
public class BaiduMapController {
@Autowired
private BaiduMapService baiduMapService;
/**
* 地理编码接口
*/
@PostMapping("/geocoding")
public BaseResponse<GeocodingResult> geocoding(@RequestBody @Valid GeocodingRequest request) {
log.info("地理编码请求: {}", request);
GeocodingResult result = baiduMapService.geocoding(request);
if (result != null) {
return BaseResponse.success(result);
} else {
return BaseResponse.error(500, "地理编码失败");
}
}
/**
* 逆地理编码接口
*/
@PostMapping("/reverse-geocoding")
public BaseResponse<ReverseGeocodingResult> reverseGeocoding(@RequestBody @Valid ReverseGeocodingRequest request) {
log.info("逆地理编码请求: {}", request);
ReverseGeocodingResult result = baiduMapService.reverseGeocoding(request);
if (result != null) {
return BaseResponse.success(result);
} else {
return BaseResponse.error(500, "逆地理编码失败");
}
}
/**
* 健康检查接口
*/
@GetMapping("/health")
public BaseResponse<String> health() {
return BaseResponse.success("百度地图服务正常运行");
}
}
2.10 启动类
BaiduMapApplication.java
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
@SpringBootApplication
@EnableConfigurationProperties
public class BaiduMapApplication {
public static void main(String[] args) {
SpringApplication.run(BaiduMapApplication.class, args);
}
}
三、接口测试
3.1 使用curl测试地理编码接口
curl -X POST http://localhost:8080/api/map/geocoding \
-H "Content-Type: application/json" \
-d '{
"address": "北京市朝阳区百度大厦",
"city": "北京市",
"retCoordtype": 1
}'
3.2 使用curl测试逆地理编码接口
curl -X POST http://localhost:8080/api/map/reverse-geocoding \
-H "Content-Type: application/json" \
-d '{
"latitude": 40.056878,
"longitude": 116.30815,
"radius": 200
}'
3.3 测试健康检查接口
curl http://localhost:8080/api/map/health
四、扩展功能实现
4.1 POI搜索功能
在BaiduMapService中添加:
/**
* POI搜索
*/
public JSONObject placeSearch(String query, String region, String location) {
try {
URIBuilder uriBuilder = new URIBuilder(baiduMapProperties.getPlaceSearchUrl());
uriBuilder.setParameter("query", query)
.setParameter("region", region)
.setParameter("output", "json")
.setParameter("ak", baiduMapProperties.getAk());
if (StringUtils.hasText(location)) {
uriBuilder.setParameter("location", location);
}
URI uri = uriBuilder.build();
String response = executeGet(uri);
return JSON.parseObject(response);
} catch (URISyntaxException e) {
log.error("URI构建异常", e);
return null;
}
}
4.2 路线规划功能
/**
* 驾车路线规划
*/
public JSONObject drivingDirection(String origin, String destination) {
try {
URIBuilder uriBuilder = new URIBuilder(baiduMapProperties.getDirectionUrl() + "/driving");
uriBuilder.setParameter("origin", origin)
.setParameter("destination", destination)
.setParameter("ak", baiduMapProperties.getAk());
URI uri = uriBuilder.build();
String response = executeGet(uri);
return JSON.parseObject(response);
} catch (URISyntaxException e) {
log.error("URI构建异常", e);
return null;
}
}
五、最佳实践
5.1 性能优化
- 连接池管理:合理配置HTTP连接池参数
- 缓存策略:对频繁请求的结果进行缓存
- 异步处理:使用异步方式处理耗时请求
- 限流控制:防止QPS超过百度地图API限制
5.2 异常处理
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(Exception.class)
public BaseResponse<?> handleException(Exception e) {
log.error("系统异常", e);
return BaseResponse.error(500, "系统内部错误");
}
}
5.3 日志记录
使用AOP记录API调用日志:
@Aspect
@Component
@Slf4j
public class BaiduMapLogAspect {
@Around("@annotation(org.springframework.web.bind.annotation.PostMapping)")
public Object logApiCall(ProceedingJoinPoint joinPoint) throws Throwable {
long start = System.currentTimeMillis();
Object result = joinPoint.proceed();
long duration = System.currentTimeMillis() - start;
log.info("API调用: {},耗时: {}ms", joinPoint.getSignature(), duration);
return result;
}
}
