Spring使用WebClient而不是Jackson的配置方式如下:
<dependencies>
<!-- Spring WebFlux -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<!-- Reactor Core -->
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
</dependency>
<!-- Reactor Netty -->
<dependency>
<groupId>io.projectreactor.netty</groupId>
<artifactId>reactor-netty</artifactId>
</dependency>
</dependencies>
@Configuration
public class WebClientConfig {
@Bean
public WebClient webClient() {
return WebClient.builder()
.exchangeStrategies(ExchangeStrategies.builder()
.codecs(configurer -> configurer.defaultCodecs().jackson2JsonDecoder(new Jackson2JsonDecoder()))
.build())
.build();
}
}
@Service
public class MyService {
private final WebClient webClient;
public MyService(WebClient webClient) {
this.webClient = webClient;
}
public Mono<MyResponse> getResponse() {
return webClient.get()
.uri("https://api.example.com/resource")
.retrieve()
.bodyToMono(MyResponse.class);
}
}
在这个例子中,我们创建了一个名为webClient
的WebClient Bean,并在配置中指定了使用Jackson进行JSON的序列化和反序列化。然后,在MyService
中注入了这个WebClient,并使用它发送GET请求并将响应转换为MyResponse
对象。
这样配置后,Spring将使用WebClient而不是默认的RestTemplate来进行HTTP通信,并且使用Jackson进行JSON的序列化和反序列化。
