遠程過程調(diào)用主要分為：服務提供者，服務消費者，通過連接對方服務器進行請求交互，來實現(xiàn)調(diào)用效果，這篇文章主要介紹了springboot3整合遠程調(diào)用,需要的朋友可以參考下

一、遠程調(diào)用

遠程過程調(diào)用：主要分為：服務提供者，服務消費者。通過連接對方服務器進行請求交互，來實現(xiàn)調(diào)用效果。

二、使用WebClient

@Service
public class WeatherServiceImpl {
    public Mono<String> weather(String city){
        //創(chuàng)建Webclient
        WebClient webClient = WebClient.create();
        HashMap<String, String> map = new HashMap<>();
        map.put("areaCn",city);
        //定義發(fā)送請求的行為
        Mono<String> mono = webClient.get()
                .uri("https://getweather.market.alicloudapi.com/lundear/weather7d?areaCn={areaCn}",map)
                .accept(MediaType.APPLICATION_JSON)//定義響應的內(nèi)容類型
                .header("Authorization", "APPCODE 05ed0debacd9479c9788b1a44266eaef")
                .retrieve()
                .bodyToMono(String.class);
        return mono;
    }
}

@RestController
public class WeatherController {
     @Autowired
     private WeatherServiceImpl weatherService;
    @GetMapping("/weather")
    public Mono<String> weather(@RequestParam("city") String city){
        return weatherService.weather(city);
    }
    @GetMapping("/hello")
    public String hello(){
        return "你好";
    }
}

三、使用HTTP Interface

public interface WeatherInterface {
    @GetExchange(url = "/lundear/weather7d",accept = "application/json")
    Mono<String> getWeather(@RequestParam("areaCn") String city,
                    @RequestHeader("Authorization") String auth);
}

 public Mono<String> weather1(String city){
        //1、創(chuàng)建客戶端
        WebClient client = WebClient.builder()
                .baseUrl("https://getweather.market.alicloudapi.com")
                .codecs(clientCodecConfigurer -> {
                    clientCodecConfigurer
                            .defaultCodecs()
                            .maxInMemorySize(256*1024*1024);
                    //響應數(shù)據(jù)量太大有可能會超出BufferSize，所以這里設置的大一點
                }).build();
        //2、創(chuàng)建工廠
        HttpServiceProxyFactory factory = HttpServiceProxyFactory
                .builder(WebClientAdapter.forClient(client)).build();
        //3、獲取代理對象
        WeatherInterface weatherInterface = factory.createClient(WeatherInterface.class);
        Mono<String> weather = weatherInterface.getWeather(city, "APPCODE 05ed0debacd9479c9788b1a44266eaef");
        return  weather;
    }

3.1、抽取方法

在配置文件中配置appcode

config配置類

@Configuration
public class RPCConfig {
    @Value("${aliyu.appcode}")
    private String appCode;
    @Bean
    HttpServiceProxyFactory factory(){
        //1、創(chuàng)建客戶端
        WebClient client = WebClient.builder()
                .defaultHeader("Authorization","APPCODE "+ appCode)
                .codecs(clientCodecConfigurer -> {
                    clientCodecConfigurer
                            .defaultCodecs()
                            .maxInMemorySize(256*1024*1024);
                    //響應數(shù)據(jù)量太大有可能會超出BufferSize，所以這里設置的大一點
                }).build();
        //2、創(chuàng)建工廠
        HttpServiceProxyFactory factory = HttpServiceProxyFactory
                .builder(WebClientAdapter.forClient(client)).build();
        return factory;
    }
    @Bean
    WeatherInterface weatherInterface(HttpServiceProxyFactory httpServiceProxyFactory){
        //3、獲取代理對象
        WeatherInterface weatherInterface = httpServiceProxyFactory.createClient(WeatherInterface.class);
        return weatherInterface;
    }
    @Bean
    AlicloudAPIService alicloudAPIService(HttpServiceProxyFactory httpServiceProxyFactory){
        AlicloudAPIService alicloudAPIService = httpServiceProxyFactory.createClient(AlicloudAPIService.class);
        return alicloudAPIService;
    }
}

public interface AlicloudAPIService {
    @GetExchange(url = "https://wuliu.market.alicloudapi.com/kdi",accept = "application/json")
    Mono<String> getWeather(@RequestParam("no") String no);
}

public interface WeatherInterface {
    @GetExchange(url = "https://getweather.market.alicloudapi.com/lundear/weather7d",accept = "application/json")
    Mono<String> getWeather(@RequestParam("areaCn") String city);
}

 @Autowired
    private WeatherInterface weatherInterface;
    @Autowired
    private AlicloudAPIService alicloudAPIService;
    public Mono<String> weather1(String city){
        Mono<String> weather = weatherInterface.getWeather(city);
        return  weather;
    }
    public Mono<String> alicloudAPI(String no){
        Mono<String> weather = alicloudAPIService.getWeather(no);
        return weather;
    }

@RestController
public class WeatherController {
     @Autowired
     private WeatherServiceImpl weatherService;
    @GetMapping("/weather")
    public Mono<String> weather(@RequestParam("city") String city){
        //return weatherService.weather(city);
        return weatherService.weather1(city);
    }
    @GetMapping("/alicloudAPI")
    public Mono<String> alicloudAPI(@RequestParam("no") String no){
        return weatherService.alicloudAPI(no);
    }
}
