QueryWrapper可以通过链式调用的方式添加条件。在代码中,可以使用`.isNull()`方法来添加IS NULL条件,使用`.like()`方法来添加LIKE条件。同时,可以使用`.and()`方法将多个条件用AND连接,使用`.or()`方法将多个条件用OR连接。例如,在给定的示例代码中,使用了`condition.isNull("pid")`来添加IS NULL条件,使用了`.like("dic_key", keyword) .or().like("***这些条件会被封装到QueryWrapper中,并在最终的SQL查询中生效。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
