MyBatis-Plus 自定义更新语句，走了自动填充方法，也赋值成功，但是打印sql 没有值，数据库也没有值

当前使用版本(必填,否则不予处理)

3.3.2

该问题是如何引起的？(确定最新版也有问题再提!!!)

    @Test
    void updateFullById() {
        TestUser tsUser = new TestUser(new BigInteger("1"));
        tsUser.setUserName("张三更新'");
        tsUser.setAge(66);
        tsUser.setModifyId(new BigInteger("3"));
        System.err.println("返回值："+testUserService.updateFullById(tsUser));
    }

sql日志：

// 手动赋值的3
3
// 自动填充方法里的时间

返回值：1

重现步骤(如果有就写完整)

1、手动添加修改者 3不添加修改时间，可以保存到数据库

2、自动填充类

    @Override
    public void updateFill(MetaObject metaObject) {
        log.info("start update fill ....");
        BigInteger currentUserId = currentUserId();
        Object modifyId = this.getFieldValByName(this.modifyId, metaObject);
        if (modifyId == null) {
            this.strictUpdateFill(metaObject, this.modifyId, BigInteger.class, currentUserId);
        }
        LocalDateTime now = LocalDateTime.now();
        Object modifyTime = this.getFieldValByName(this.modifyTime, metaObject);
        if (modifyTime == null) {
            this.strictUpdateFill(metaObject, this.modifyTime, LocalDateTime.class, now);
        }
      //  走了 方法，有值
        System.out.println(this.getFieldValByName(this.modifyId, metaObject));
        System.out.println(this.getFieldValByName(this.modifyTime, metaObject));

    }

3、xml语句

    <update id="updateFullById" parameterType="TestUser" >
        UPDATE test_user t
        <set>
            <include refid="UpdateFullFieldList">
                <property name="joiner" value=""/>
            </include>
        </set>
        WHERE t.id = #{id}
    </update>


<sql id="UpdateFullFieldList">
        <choose>
            <when test="${joiner}modifyId != null">
                t.modify_id = #{${joiner}modifyId},
            </when>
            <otherwise>
                t.modify_id = 2,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}modifyTime != null">
                t.modify_time = #{${joiner}modifyTime},
            </when>
            <otherwise>
                t.modify_time = NULL,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}uid != null and ${joiner}uid != ''">
                t.uid = #{${joiner}uid},
            </when>
            <otherwise>
                T.uid = NULL,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}userName != null and ${joiner}userName != ''">
                t.user_name = #{${joiner}userName},
            </when>
            <otherwise>
                T.user_name = NULL,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}sex != null and ${joiner}sex != ''">
                t.sex = #{${joiner}sex},
            </when>
            <otherwise>
                T.sex = NULL,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}age != null">
                t.age = #{${joiner}age},
            </when>
            <otherwise>
                t.age = NULL,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}birthday != null">
                t.birthday = #{${joiner}birthday},
            </when>
            <otherwise>
                t.birthday = NULL,
            </otherwise>
        </choose>
        <choose>
            <when test="${joiner}fkByUnitId != null and ${joiner}fkByUnitId.id != null">
                t.unit_id = #{${joiner}fkByUnitId.id},
            </when>
            <otherwise>
                t.unit_id = NULL,
            </otherwise>
        </choose>
    </sql>

4、实体类

    /**
     * 修改人
     */
    @TableField(fill = FieldFill.INSERT_UPDATE)
    protected BigInteger modifyId;

    /**
     * 修改时间
     */
    @TableField(fill = FieldFill.INSERT_UPDATE)
    protected LocalDateTime modifyTime;

因为set值是在ognl之后进行的,所以对应的字段不能判null
