简单记录下RestTemplate使用方法

1.设置get方法

ResponseEntity<JSONObject> responseEntity= restTemplate.getForEntity（url,JSONObject.class）；

2.设置post方法

 MultiValueMap map = new LinkedMultiValueMap();

   map.add("name", name);

 ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(url, map, JSONObject.class);

3.put方法

  MultiValueMap map = new LinkedMultiValueMap();

    map.add("username", "username");

    map.add("address", "address");

    restTemplate.put(url, map);

4.delete方法

 restTemplate.delete(url, model);

5.配置文件(无配置不可使用)

public class RestConfig {

    //不重要

    @Bean

    public CloseableHttpClient httpClient() throws Exception {

        SSLContext context = new SSLContextBuilder().loadTrustMaterial(null, (x509Certificates, s) -> true).build();

        SSLConnectionSocketFactory factory = new SSLConnectionSocketFactory(context, NoopHostnameVerifier.INSTANCE);

        return HttpClients.custom()

                .setSSLSocketFactory(factory)

                .build();

    }

    //不重要

    @Bean

    public ClientHttpRequestFactory httpRequestFactory() throws Exception {

        HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();

        factory.setHttpClient(httpClient());

        factory.setConnectionRequestTimeout(3000);

        factory.setReadTimeout(30000);

        factory.setConnectTimeout(30000);

        return factory;

    }

   //必须要

    @Bean

    public RestTemplate restTemplate() throws Exception {

        return new RestTemplate(httpRequestFactory());

    }

}
