将OrderBy与JPararePository一起使用

Question

我有一个代码是这样的：

public interface BatchExecuteHistoryRepository extends JpaRepository<BatchExecuteHistory, Long> {
Page<BatchExecuteHistory> findByBatchExecuteHistoryIdBatchIdOrderByTimeEndAsc(String batchId, Pageable pageable);

}

有人知道为什么查询不能使用Order By time_end ASC吗？？？我尝试了FindByBatchExecuteHistoryIdBatchId（String batchId,Pageable Pageable)并得到了相同的结果

public class BatchExecuteHistory implements Serializable {

private static final long serialVersionUID = 1L;

@EmbeddedId
private BatchExecuteHistoryId batchExecuteHistoryId;

@NotNull
@Size(max = 100)
@Column(name = "batch_name", length = 100, nullable = false)
private String batchName;

@NotNull
@Column(name = "status", nullable = false)
private Boolean status;

@NotNull
@Column(name = "time_end", nullable = false)
private Instant timeEnd;

@Size(max = 100)
@Column(name = "error_step", length = 100)
private String errorStep;

@Size(max = 100)
@Column(name = "error_content", length = 100)
private String errorContent;

@Column(name = "row_input")
private Long rowInput;

public BatchExecuteHistoryId getBatchExecuteHistoryId() {
    return batchExecuteHistoryId;
}

public void setBatchExecuteHistoryId(BatchExecuteHistoryId batchExecuteHistoryId) {
    this.batchExecuteHistoryId = batchExecuteHistoryId;
}

public Boolean getStatus() {
    return status;
}

public String getBatchName() {
    return batchName;

public BatchExecuteHistory batchName(String batchName) {
    this.batchName = batchName;
    return this;

    this.status = status;
    return this;

    this.status = status;

public Instant getTimeEnd() {
    return timeEnd;
}

public BatchExecuteHistory timeEnd(Instant timeEnd) {
    this.timeEnd = timeEnd;
    return this;
}

public void setTimeEnd(Instant timeEnd) {
    this.timeEnd = timeEnd;
}

public String getErrorStep() {
    return errorStep;

    return this;

    this.errorContent = errorContent;

public Long getRowInput() {
    return rowInput;

    this.rowInput = rowInput;
    return this;
}

public void setRowInput(Long rowInput) {
    this.rowInput = rowInput;
}

@Override

Answer 1

您应该在OrderBy之前添加By，因此您的方法应该是:FindByBatchExecuteHistoryIdBatchIdByorDerByTimeEndAsc
