Springboot RestTemplate设置超时时间的简单方法

@Configuration
public class RestTemplateConfig {
    @Bean
    public RestTemplate getRestTemplate() {
        //配置HTTP超时时间
        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();
        httpRequestFactory.setConnectionRequestTimeout(6000);
        httpRequestFactory.setConnectTimeout(6000);
        httpRequestFactory.setReadTimeout(6000);
        return new RestTemplate(httpRequestFactory);
    }
}

custom.rest.connection.connection-request-timeout=3000
custom.rest.connection.connect-timeout=3000
custom.rest.connection.read-timeout=3000

@Configuration
public class AppConfig{
    @Bean
    @ConfigurationProperties(prefix = "custom.rest.connection")
    public HttpComponentsClientHttpRequestFactory customHttpRequestFactory() {
        return new HttpComponentsClientHttpRequestFactory();
    }
???????    @Bean
    public RestTemplate customRestTemplate(){
        return new RestTemplate(customHttpRequestFactory());
    }
}

long s = System.currentTimeMillis();
        try {
            responseEntity = restTemplate.exchange();
        } catch (Exception e) {
            long costTime = System.currentTimeMillis()-s;
            log.error("调用**服务异常,花费时间:{},错误:{}",costTime, e.getMessage(), e);
        }
