反序列化json字符串的反序列化异常

Question

得到

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: 

Unrecognized field "operationMessage" (class worker.lib.message.OperationMessage), not marked as ignorable (9 known properties: "packageMessage", "sourceAsset", "operation", "publishMessage", "requestId", "remixMessage", "targetAsset", "jobId", "intermediates"])
    
 at [Source: (String)"{"operationMessage":{"sourceAsset":{"path":"/a/b/c.txt","repoId":"testId","region":"va6"},"targetAsset":{"path":"/folder4","repoId":"id2","region":"va6"},"jobId":"7c540211d1054442940211d10594426e","intermediates":false}}"; line: 1, column: 22] (through reference chain: 
worker.lib.message.OperationMessage["operationMessage"])

我的 OperationMessage 类是

@JsonInclude(JsonInclude.Include.NON_NULL)
@Data //generates getter and setters
public class OperationMessage {
  
  @JsonProperty(value = "jobId")
  private String jobId;
  
  @JsonProperty(value = "operation")
  private Operation operation;
  
  @JsonProperty(value = "intermediates")
  private Boolean intermediates; //for copy-move 
  
  private AssetProperties sourceAsset;
  
  private AssetProperties targetAsset;
  
  private PublishMessage publishMessage; //fields related to publish Operation. 
  
  private RemixMessage remixMessage; //fields related to remix Operation.
  
  private PackageMessage packageMessage;//fields related to package Operation

  private String requestId;

  @Override
  public String toString() {
    return "OperationMessage [jobId=" + jobId + ", operation=" + operation + "]";
  }
  

}

有人可以提出这里的问题吗？

Answer 1

您应该做的一些事情如下：

1) 为类的成员变量添加 getter 和 setter

2) 添加默认构造函数public class OperationMessage { }

3) 实现Serializablepublic class OperationMessage implements Serializable

4) 将@JsonIgnoreProperties(ignoreUnknown = true) 注解添加到您的 POJO

Answer 2

您没有 getter 和 setter...或者将这些字段更改为公开的。
