Question

获取

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 + "]";
  }
  

}

有人可以建议这里有什么问题吗？

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setters

2）添加默认构造函数import pyodbc import pandas as pd #Database Connection conn = pyodbc.connect(driver='xxxxxx', server='xxxxxxx', database='xxxxxx', user='xxxxxx', password='xxxxxxxx') cursor = conn.cursor() depts = ['Human Resources','Accounting','Marketing'] # gives you the string to use in your sql query: depts_query_string = "('{query_vals}')".format(query_vals="','".join(depts)) query = """ SELECT * FROM device ID WHERE Department in {query_vals} AND Status like 'Active' """.format(query_vals=depts_query_string) target = r'O:\\Example' today = target + os.sep + time.strftime('%Y%m%d') if not os.path.exists(today): os.mkdir(today) for i in departments: #workbook = Workbook(today + os.sep + i + 'xlsx') #worksheet = workbook.add_worksheet() P_data = pd.read_sql(query, conn) P_data.to_excel(today + os.sep + i + 'xlsx')

3）实施public class OperationMessage { } Serializable

4）将public class OperationMessage implements Serializable注释添加到您的POJO

Answer 2

您没有getter和setter ...或将这些字段更改为公开字段。
