RestTemplate基本配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

/**
 * RestTemplate注入，配置超时时间
 */
@Configuration
public class RestTemplateConfig {

    @Bean
    public RestTemplate getRestTemplate() {
        // 配置HTTP超时时间为5s
        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();
        httpRequestFactory.setConnectTimeout(5000);
        httpRequestFactory.setReadTimeout(5000);
        return new RestTemplate(httpRequestFactory);
    }
}
