将OrderBy与JPARepository一起使用

Question

我有这样的代码：

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

}

这是我的数据库：

以下是我在网站上的内容：

任何人都知道为什么查询无法使用Order by time_end ASC ??? 我尝试了findByBatchExecuteHistoryIdBatchId(String batchId, Pageable pageable)并获得了相同的结果

请注意，BatchExecuteHistoryId是复合ID，而batchId是它的元素

更新，这是我的BatchExecuteHistory类：

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;
}

public void setBatchName(String batchName) {
    this.batchName = batchName;
}

public Boolean isStatus() {
    return status;
}

public BatchExecuteHistory status(Boolean status) {
    this.status = status;
    return this;
}

public void setStatus(Boolean status) {
    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;
}

public BatchExecuteHistory errorStep(String errorStep) {
    this.errorStep = errorStep;
    return this;
}

public void setErrorStep(String errorStep) {
    this.errorStep = errorStep;
}

public String getErrorContent() {
    return errorContent;
}

public BatchExecuteHistory errorContent(String errorContent) {
    this.errorContent = errorContent;
    return this;
}

public void setErrorContent(String errorContent) {
    this.errorContent = errorContent;
}

public Long getRowInput() {
    return rowInput;
}

public BatchExecuteHistory rowInput(Long rowInput) {
    this.rowInput = rowInput;
    return this;
}

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

@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + ((batchExecuteHistoryId == null) ? 0 : batchExecuteHistoryId.hashCode());
    result = prime * result + ((batchName == null) ? 0 : batchName.hashCode());
    result = prime * result + ((errorContent == null) ? 0 : errorContent.hashCode());
    result = prime * result + ((errorStep == null) ? 0 : errorStep.hashCode());
    result = prime * result + ((rowInput == null) ? 0 : rowInput.hashCode());
    result = prime * result + ((status == null) ? 0 : status.hashCode());
    result = prime * result + ((timeEnd == null) ? 0 : timeEnd.hashCode());
    return result;
}

@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())

            return false;

@Override

Answer 1

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