RestTemplate YAMA isteği

Question

Ben PersonDTO için aşağıdakileri ifade edecektir:

{ 
    "id": 1, 
    "firstName": "John", 
    "lastName": "Doe", 
    "maritalStatus": "married" 
} 

Şimdi, John Doe boşanmış alır:

İşte

public class PersonDTO 
{ 
    private String id 
    private String firstName; 
    private String lastName; 
    private String maritalStatus; 
} 

örnek bir kaydıdır. Bu yüzden bu URL'ye bir YAMA isteği göndermek gerekir: Aşağıdaki istek vücutla

http://localhost:8080/people/1 

:

{ 
    "maritalStatus": "divorced" 
} 

ben bunu nasıl anlamaya olamaz. İşte ben bugüne kadar çalıştığı şey budur: Sadece MaritalStatus kuruyorum gibi

1), diğer alanlarda tüm boş olacaktır: Burada

// Create Person 
PersonDTO person = new PersonDTO(); 
person.setMaritalStatus("Divorced"); 

// Create HttpEntity 
final HttpEntity<ObjectNode> requestEntity = new HttpEntity<>(person); 

// Create URL (for eg: localhost:8080/people/1) 
final URI url = buildUri(id); 

ResponseEntity<Void> responseEntity = restTemplate.exchange(url, HttpMethod.PATCH, requestEntity, Void.class); 

yukarıdaki ile problemlerdir. Ben istek çıktısını Yani, eğer bu gibi görünecektir:

{ 
    "id": null, 
    "firstName": "null", 
    "lastName": "null", 
    "maritalStatus": "married" // I only need to update this field. 
} 

ben bir PATCH yapmadan önce bir GET gerektiği anlamına mı geliyor?

2) Aşağıdaki yığın izini alıyorum:

Spring'in RestTemplate kullanarak dinlendirici webservice tüketmek istemci uygulamaları yazdım millet herhangi işaretçiler değerlendirin.

Tamlık sağlamak için, arka uç uca dayanan web servislerimiz için SpringDataRest'i kullandığımızı da belirtmeme izin verin.

Answer 1

sadece benim restTemplate örneğine yeni HttpRequestFactory ekleyerek bu sorunu çözdü. Bu

RestTemplate restTemplate = new RestTemplate(); 

HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(); 
requestFactory.setConnectTimeout(TIMEOUT); 
requestFactory.setReadTimeout(TIMEOUT); 

restTemplate.setRequestFactory(requestFactory); 

PS gibi: Eğer projede HttpClient bileşen eklemek gerekir

RestTemplate, özel RestClient için yapıcı olarak yazılabilir bir RestTemplateBuilder inşa edilmiştir durumlarda

<dependency> 
    <groupId>org.apache.httpcomponents</groupId> 
    <artifactId>httpclient</artifactId> 
    <version>4.4.1</version> 
</dependency> 

Answer 2

,

public PersonRestClient(RestTemplateBuilder restTemplateBuilder) { 
    this.restTemplate = restTemplateBuilder.requestFactory(new HttpComponentsClientHttpRequestFactory()).build(); 
} 

Ayrıca, org.apache.httpcomponents.httpclient bağımlılığının pompaya eklenmesi gerekir.
