java - 使用 RestTemplate 和 Jackson 反序列化对 Java 的 JSON 响应

Question

我在使用 Jackson 在 Spring Boot 1.5 应用程序中将 JSON 反序列化为 Java 对象时遇到了一些麻烦。

如下所示，JSON 响应是一个由单个 JSON 对象和一些嵌套属性组成的数组:

[
  {
    "deploymentProject": {
        "id": 57966596,
        "name": "MyApp 6.3"
    },
    "environmentStatuses": [{
            "environment": {
                "id": 57245736,
                "name": "Dev1",
                "deploymentProjectId": 57966596
            },
            "deploymentResult": {
                "deploymentVersionName": "App-51",
                "id": 59769040
            }
        },
        {
            "environment": {
                "id": 57245737,
                "name": "Dev2",
                "deploymentProjectId": 57966596
            },
            "deploymentResult": {
                "deploymentVersionName": "App-51",
                "id": 59769041
            }
        }
    ]
  }
]

ResultData.java

我不关心 deploymentProject 属性，因此我只在 ResultData 中包含 environmentStatuses。

@JsonIgnoreProperties(ignoreUnknown = true)
public class ResultData {   
  private EnvironmentStatus[] environmentStatuses;

  // Getters and setters omitted
}

EnvironmentStatus.java

@JsonIgnoreProperties(ignoreUnknown = true)
public class EnvironmentStatus {

    private Environment environment;
    private DeploymentResult deployment;

    // Getters and setters omitted
}

Environment.java

@JsonIgnoreProperties(ignoreUnknown = true)
public class Environment {
    private long id;
    private String name;
    private String deploymentProjectId;
    //Getters and setters omitted
}

DeploymentResult.java

@JsonIgnoreProperties(ignoreUnknown = true)
public class DeploymentResult {
    private long id;
    private String deploymentVersionName;
    // Getters and setters omitted
}

当我在服务类中调用 RestTemplate 时，environmentStatuses 数组为 null:

Service.java

ResponseEntity<List<ResultData>> response = restTemplate.exchange(uriBuilder.toUriString(),
                HttpMethod.GET, null, new ParameterizedTypeReference<List<ResultData>>() {});

return response.getBody();

私有(private) DeploymentResult 部署； 是下一期.. 如果您希望在代码中使用此名称，则需要使用 json 结构名称进行注释。或者如果没有命名为deploymentResult
