Spring引导Rest模板-CloseableHttpClient

我正在Spring boot应用程序中定义CloseableHttpClient类型的bean。但是我仍然得到了一个错误，那就是找不到bean

@Bean
@Primary
public RestTemplate restTemplate(RestTemplateBuilder builder, @Qualifier("pooledClient") CloseableHttpClient httpClient) {
    return builder.requestFactory(new HttpComponentsClientHttpRequestFactory(httpClient)).build();
}

@Bean
public CloseableHttpClient httpClient() {
    return HttpClientBuilder.create().build();
}

com.MyConfiguration中方法restTemplate的参数1需要找不到类型为“org.apache.http.impl.client.CloseableHttpClient”的bean

@Bean
@Primary
public RestTemplate restTemplate(RestTemplateBuilder builder, @Qualifier("pooledClient") CloseableHttpClient httpClient) {
    return builder.requestFactory(new HttpComponentsClientHttpRequestFactory(httpClient)).build();
}

@Bean
public CloseableHttpClient httpClient() {
    return HttpClientBuilder.create().build();
}

行动：

---

考虑在您的配置中定义“org.apache.http.impl.client.CloseableHttpClient”类型的bean。

您正在为CloseableHttpClient使用

@限定符

，但在您的配置中，您没有定义任何与该限定符匹配的bean。您可以声明一个名为pooledClient的bean：

@Bean(name="pooledClient")
public CloseableHttpClient httpClient() {
    return HttpClientBuilder.create().build();
}

或者删除@Qualifier注释：

@Bean
@Primary
public RestTemplate restTemplate(RestTemplateBuilder builder, CloseableHttpClient httpClient) {
    return builder.requestFactory(new HttpComponentsClientHttpRequestFactory(httpClient)).build();
}
