Java通过mybatis插入Oracle数据库中Date格式不显示到时分秒问题

我在用mybatis generator生成代码后，执行查询语句时，Oracle里的Date类型字段只精确到年月日，后面时分秒都为零。

后来发现是jdbcType问题，改成 jdbcType="TIMESTAMP" 就可以。（原先默认生成时是jdbcType="DATE"）

ps：实体类里Date是Java.util.Date包里的，不是java.sql.Date，否则也会只精确到年月日

实体类

package com.pcmall.domain.sale.erps;

import java.util.Date;

public class Synnexlogs {
    private String sender;

    private String receiver;

    private Date calltime;

    private String inputparam;

    private String outputparam;

    private String type;

    private String remark;

    public String getSender() {
        return sender;
    }

    public void setSender(String sender) {
        this.sender = sender == null ? null : sender.trim();
    }

    public String getReceiver() {
        return receiver;
    }

    public void setReceiver(String receiver) {
        this.receiver = receiver == null ? null : receiver.trim();
    }

    public Date getCalltime() {
        return calltime;
    }

    public void setCalltime(Date calltime) {
        this.calltime = calltime;
    }

    public String getInputparam() {
        return inputparam;
    }

    public void setInputparam(String inputparam) {
        this.inputparam = inputparam == null ? null : inputparam.trim();
    }

    public String getOutputparam() {
        return outputparam;
    }

    public void setOutputparam(String outputparam) {
        this.outputparam = outputparam == null ? null : outputparam.trim();
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type == null ? null : type.trim();
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark == null ? null : remark.trim();
    }
}
