Java时间在Mysql表中插入

Question

我有一个简单的字符串列表，其中包含以下数据示例。我能够将列表中的数据传递到具有 Date 类型字段的实体类，我还执行字符串到日期的转换
SimpleDateFormat sTime = new SimpleDateFormat("HH:mm") this.itime = sTime.parse(itime);在将其插入数据库之前。

问题:插入表中的时间值不正确!。我哪里出错了？

希望我已经提供了足够的信息供您制定答案。

示例数据

ZZZZ,T0001,00:15:39,15-NOV-2019
ZZZZ,T0002,00:30:39,15-NOV-2019
ZZZZ,T0003,00:45:39,15-NOV-2019
...
...
...

这是我的代码片段，用于从列表中提取时间(第三个值)

map.entrySet().stream().forEach(v -> { 
                String[] items = v.split(",");
                if (items[0].equals("ZZZZ")) { 
                    slice[0] = items[1];
                    mTime[0] = items[2];
                    mDate[0] = items[3];
                    try {
                        // load data into nmon_interval table
                        IntervalData i = new IntervalData(hostId,slice[0],mDate[0],mTime[0]);
System.out.println("mTime[0] :"+mTime[0]+ ", TSLICE: "+ slice[0] );
                             System.out.println("ITIME: "+i.getItime()+", TSLICE: "+i.getTslice());
                        r.save(i);

这是 IntervalData 类...

@Entity
public class IntervalData {


    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "interval_generator")
    @SequenceGenerator(name = "interval_generator", sequenceName = "interval_seq")
    private Long id;
    private String tslice;
    @Temporal(TemporalType.DATE)
    private Date idate;
    @Temporal(TemporalType.TIME)
    private Date  itime;

    @ManyToOne
    //@JoinColumn(name = "id" , nullable = false)
    private Host host; 

    @Transient
    SimpleDateFormat sTime = new SimpleDateFormat("HH:mm");
    @Transient
    SimpleDateFormat sDate = new SimpleDateFormat("DD-MMM-yyyy");


    public IntervalData() {
        super();
    }

    public IntervalData(Long hostId, String tslice, String idate, String itime) throws ParseException {
        this.tslice = tslice;
        this.itime = sTime.parse(itime);
        this.idate = sDate.parse(idate);
        this.host = new Host(hostId,"");
    }

日志输出...

ITIME: Thu Jan 01 00:15:00 PST 1970, TSLICE: T0001

Mysql数据库表定义和查询结果...

select * from nmon_interval order by 4 desc;

很可能是时区问题。您需要检查您的 MySQL 时区设置并将其设置为 UTC
