mybatis plus or括号

MyBatis Plus supports the OR condition using the `or` method provided by the `QueryWrapper` class. To use OR conditions with parentheses, you can chain multiple `or` methods together.

Here's an example:

QueryWrapper<Entity> queryWrapper = new QueryWrapper<>();
queryWrapper.eq("column1", value1)
    .or()
    .eq("column2", value2)
    .or()
    .nested(wrapper -> wrapper.eq("column3", value3).ne("column4", value4));

In the above example, `eq` represents the equal condition, `ne` represents the not equal condition, and `nested` is used to create a nested condition with parentheses.

You can adjust the conditions and column names based on your requirements.
