Question

我在Springboot应用程序中使用JdbcBatchItemWriter将数据从CSV文件导入到Oracle DB中，但无法导入时间戳。我收到错误Failed to convert property value of type 'java.lang.String' to required type 'java.time.LocalDateTime 我了解错误-我只是不知道如何解决。有没有办法标记插入语句，以便将其作为时间戳读取？

我确实尝试过： INSERT INTO HB357(START_DATE) VALUES (TO_DATE(:START_DATE, YYYY-MM-DD, HH:mm:SS) 我试过了 TO_TIMESTAMP(:START_DATE, YYYY-MM-DD HH24:mm:SS) 但这没用

我还尝试将实体类型更改为String而不是LocalDataTime，但这会导致not a valid month错误。因此，我然后尝试在插入之前更改会话（实体类型仍为字符串）： itemWriter.setSql("ALTER SESSION SET NLS_DATE_FORMAT = 'YYYY-MM-DD HH24:MI:SS' NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH24:MI:SS'"); 然后运行插入状态，但也出现not a valid month错误

ENTITY：

@Entity
@NamedQuery(name ="HB357.getListOfResponseIds", query = "SELECT RESPONSE_ID from HB357")
public class HB357 {

    @Id
    private String RESPONSE_ID;
    @JsonFormat(pattern="yyyy-MM-dd@HH:mm:ss")
    private LocalDateTime START_DATE;
    private String STOVE_OPTION;
    private String FIRST_NAME;
    private String LAST_NAME;
    private String ADDRESS;
    private String CITY;
    private String ZIPCODE;
    private String COUNTY;

//Getters and Setters left out for brevity

        JdbcBatchItemWriter<HB357> itemWriter = new JdbcBatchItemWriter<>();
        itemWriter.setDataSource(appProperties.dataSource());
        itemWriter.setSql("INSERT INTO HB357 (" +
                "START_DATE, RESPONSE_ID, STOVE_OPTION, FIRST_NAME,LAST_NAME,ADDRESS,CITY,ZIPCODE,COUNTY,PHONE_NUMBER,EMAIL," +
                "STOVE_LOCATION,EXEMPTIONS,AGI,INCENTIVE,INCENTIVE_AMT) " +
                "VALUES (:START_DATE, :RESPONSE_ID, :STOVE_OPTION, :FIRST_NAME, :LAST_NAME, :ADDRESS, :CITY," +
                ":ZIPCODE, :COUNTY, :PHONE_NUMBER, :EMAIL, :STOVE_LOCATION, :EXEMPTIONS, :AGI," +
                ":INCENTIVE, :INCENTIVE_AMT)" );
        itemWriter.setItemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<>());
        return itemWriter;
    }
