Spring反应返回scanAvailable和Prefetch而不是Object-Java问题

Spring reactive returns scanAvailable and prefetch instead of object(Spring反应返回scanAvailable和Prefetch而不是Object)

本文介绍了Spring反应返回scanAvailable和Prefetch而不是Object的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个用Spring active开发的rest API，如下所示，当它返回响应时，它确实有scanAvailable和预取，而不是对象详细信息。对于findAllEmployee，getAllWorkerAddressDetailsByWorkerId下面使用的方法，我们有单独的API，它确实返回了正确的响应。当我将它们组合在一起时，我不确定哪里出了问题。

WorkerDTO.java

@Builder
@NoArgsConstructor
@AllArgsConstructor
@Data
@ToString(includeFieldNames = true)
public class WorkerDTO {
    
    ...

    private Flux<WorkerAddressDTO> workerAddress;

}

ServiceImpl.java

@Override
public Flux<WorkerDTO> method() {
  Flux<EmploymentDTO> employmentDTOFlux = findAllEmployment();
  Flux<WorkerDTO> workerDTOFlux = getWorkerDetailsWithEmploymentStatus(employmentDTOFlux);
  return workerDTOFlux.flatMap(workerDTO -> {
    workerDTO.setWorkerAddress(getAllWorkerAddressDetailsByWorkerId(workerDTO.getWorkerId()).map(workerAddressDTO -> workerAddressDTO));
     return Flux.just(workerDTO);
  });
}

当前响应：

[
    {
        "xyz": "abc",
        "workerAddress": {
            "scanAvailable": true,
            "prefetch": -1
        }
    },
    {
       "xyz": "qwe",
        "workerAddress": {
            "scanAvailable": true,
            "prefetch": -1
        }
    } 
]

预期响应：

[
    {
        "xyz": "abc",
        "workerAddress": {
            "key1": "value1",
            "key2": "value2"
        }
    },
    {
       "xyz": "qwe",
        "workerAddress": {
            "key1": "value1",
            "key2": "value2"
        }
    } 
]

推荐答案

您需要做一些更改。首先，将Flux放在WorkerDTO中，并替换为List，如下所示：

@Builder
@NoArgsConstructor
@AllArgsConstructor
@Data
@ToString(includeFieldNames = true)
public class WorkerDTO {
    
    ...

    private List<WorkerAddressDTO> workerAddress;
}

然后，您需要按如下方式更改ServiceImpl代码：

@Override
public Flux<WorkerDTO> method() {
    Flux<EmploymentDTO> employmentDTOFlux = findAllEmployment();
    Flux<WorkerDTO> workerDTOFlux = getWorkerDetailsWithEmploymentStatus(employmentDTOFlux);
    return workerDTOFlux.flatMap(workerDTO -> {
         return getAllWorkerAddressDetailsByWorkerId(workerDTO.getWorkerId()).collectList()
            .map(workerAddresses -> workerDTO.setWorkerAddress(workerAddresses));
    });
}
