Mybatis-Plus的saveOrUpdateBatch(null)问题及解决

  @ApiModelProperty(value = "固定电话")
    @TableField(value = "FIXED_TELEPHONE",updateStrategy = FieldStrategy.IGNORED)
    private String fixedTelephone;

service.savaOrUpdate(User user);

 public boolean saveOrUpdate(T entity) {
        if (null == entity) {
            return false;
        } else {
            TableInfo tableInfo = TableInfoHelper.getTableInfo(this.entityClass);
            Assert.notNull(tableInfo, "error: can not execute. because can not find cache of TableInfo for entity!", new Object[0]);
            String keyProperty = tableInfo.getKeyProperty();
            Assert.notEmpty(keyProperty, "error: can not execute. because can not find column for id from entity!", new Object[0]);
            Object idVal = tableInfo.getPropertyValue(entity, tableInfo.getKeyProperty());
            return !StringUtils.checkValNull(idVal) && !Objects.isNull(this.getById((Serializable)idVal)) ? this.updateById(entity) : this.save(entity);
        }
    }

!StringUtils.checkValNull(idVal) && !Objects.isNull(this.getById((Serializable)idVal)) ? this.updateById(entity) : this.save(entity);

!StringUtils.checkValNull(idVal)

!Objects.isNull(this.getById((Serializable)idVal))
