Question

春天和其他事物的新手。尝试命中端点并在响应字段中检索信息。但是我不知道如何获取信息而不是仅仅返回整个响应，因为它不嵌套在键/值中？

我正在使用剩余模板+ MappingJacksonHttpMessageConverter。我想将信息映射到响应pojo中，只是不确定如何进行进一步操作，或者不确定我是否在正确的方向上。下面的示例代码。

邮差：

{
    "success": true,
    "message": "Success",
    "body": {
        "response": "TopStatus=Completed,TopRanking=4 - reqs met, TopDate=2014-04-23,TopTime=11:00 AM,TopEndTime=1:30 AM"
    },
    "status": 200
}

试图映射到Pojo的方法

public TopStatus getTopAppStatus(int topId, Status status) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HashMap<String, String> statusObj = new HashMap<String, String>();
    statusObj.put("topStatus", "Fail");
    statusObj.put("topId", "93");

    RestTemplate rt = getRestTemplate();
    URI uri = new URI("urihere");
    HttpEntity<HashMap> entity = new HttpEntity<HashMap>(statusObj, headers);
    TopStatus response = rt.postForObject(uri, entity, TopStatus.class);

    return response;
}

关于如何设置的Pojo示例

@JsonIgnoreProperties(ignoreUnknown = true)
public class TopStatus{

    @JsonProperty("TopStatus")
    private String topStatus;

    rest of fields, setters, getters etc...

}

Answer 1

您可以使用postForEntity（）方法返回ResponseEntity类型的对象，而不是 postForObject（）

您需要进行一些小的更改，以将响应主体映射到POJO

ResponseEntity<TopStatus> response = rt.postForEntity(uri, entity, TopStatus.class);
TopStatus topStatusResponse = response.getBody();
return topStatusResponse;

这应该只返回预期的POJO。

尝试使用以下代码。

public TopStatus getTopAppStatus(int topId, Status status) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    TopStatus model = new TopStatus();
    model.setTopStatus("Fail");
    model.setTopId("93");

    RestTemplate rt = getRestTemplate();
    URI uri = new URI("urihere");
    HttpEntity<> entity = new HttpEntity<HashMap>(model, headers);
    TopStatus response = rt.postForObject(uri, entity, TopStatus.class);

    return response;
}

修改后的代码。

public TopStatus getTopAppStatus(int topId, Status status) {

    RestTemplate restTemplate = new RestTemplate();
    // Add the Jackson message converter
    restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
    // create request body
    //Here your TopStatus object converted to json. you can use Jackson to do this. 
    String input = "{\"topStatus\":\"Fail\",\"topId\":\"93\"}";


    // set headers
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<String> entity = new HttpEntity<String>(input, headers);

    URI uri = new URI("urihere");
    ResponseEntity<TopStatus> response = restTemplate
        .exchange(uri, HttpMethod.POST, entity, TopStatus.class);

    return response;
}

如何使用此响应主体解析对POJO的响应
