postgresql 按日期范围查询

实体类

package com.yunhe.jvmjiazai;

import java.util.Date;

/**

public class Order {

    private String name;

    private Date createTime;//订单的创建时间，保存到数据库中,在数据库中类型为timestamp

    private String beginTime;//前端传到后端的开始时间，不需要保存数据库中

    private String endTime;//前端传到后端的结束时间，不需要保存数据库中

    public Order() {
    }

    public Order(String name, Date createTime, String beginTime, String endTime) {
        this.name = name;
        this.createTime = createTime;
        this.beginTime = beginTime;
        this.endTime = endTime;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public String getBeginTime() {
        return beginTime;
    }

    public void setBeginTime(String beginTime) {
        this.beginTime = beginTime;
    }

    public String getEndTime() {
        return endTime;
    }

    public void setEndTime(String endTime) {
        this.endTime = endTime;
    }

    @Override
    public String toString() {
        return "Order{" +
                "name='" + name + '\'' +
                ", createTime=" + createTime +
                ", beginTime='" + beginTime + '\'' +
                ", endTime='" + endTime + '\'' +
                '}';
    }
}

这里我用的数据库语言是 postgresql ，在日期上处理不同于MySQL数据库

查询在开始时间到结束时间中所有创建的订单信息（开始时间与结束时间均是前端传来的）

 <select id="findLike" resultType="com.yunhe.entity.Order">
        select *
        from order
        <where>
            <if test="beginTime!=null and beginTime!=''">
                and createTime >= to_date(#{beginTime},'yyyy-mm-dd')
                <--and createTime  &gt;= to_date(#{beginTime}, 'yyyy-mm-dd')-->
            </if>
            <if test="endTime!=null and endTime!=''">
                and createTime < to_date(#{endTime},'yyyy-mm-dd')
                <--and createTime  &lt;= to_date(#{endTime}, 'yyyy-mm-dd')-->
            </if>
        </where>
    </select>
