RestTemplate配置类和工具类
RestTemplate配置类
@Configuration public class RestTemplateConfig { @Bean public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) { RestTemplate build = restTemplateBuilder .requestFactory(OkHttp3ClientHttpRequestFactory.class) .setConnectTimeout(Duration.ofSeconds(10)) .setReadTimeout(Duration.ofSeconds(20)) .build(); build.getMessageConverters().add(new TextJsonSupport(Jackson2ObjectMapperBuilder.json().build())); return build; } } public class TextJsonSupport extends MappingJackson2HttpMessageConverter { public TextJsonSupport(ObjectMapper objectMapper) { super(objectMapper); setSupportedMediaTypes(Arrays.asList(new MediaType("text", "json"))); } public TextJsonSupport() { super(); } }
RestTemplate工具类
public class RestTemplateUtil { public static Object doGet(String url, HttpHeaders httpHeaders) { RestTemplate restTemplate = new RestTemplate(); HttpEntity<Object> request = new HttpEntity<>(httpHeaders); ResponseEntity<Object> result = restTemplate.exchange(url, HttpMethod.GET, request, Object.class); if (null != result && null != result.getBody()) { return result.getBody(); } return null; } public static Object doPost(String url, HttpHeaders httpHeaders, JSONObject params) { RestTemplate restTemplate = new RestTemplate(); HttpEntity<Object> request = new HttpEntity<>(params, httpHeaders); ResponseEntity<Object> result = restTemplate.exchange(url, HttpMethod.POST, request, Object.class); if (null != result && null != result.getBody()) { return result.getBody(); } return null; } public static Object doPostJson(String url, HttpHeaders httpHeaders, JSONObject params) { RestTemplate restTemplate = new RestTemplate(); HttpEntity<Object> request = new HttpEntity<>(params, httpHeaders); ResponseEntity<JSONObject> result = restTemplate.exchange(url, HttpMethod.POST, request, JSONObject.class); if (null != result && null != result.getBody()) { return result.getBody(); } return null; } }
