MySQL uses list as a parameter to query

Summary ： Two fields are needed to determine A piece of data , Name and... According to the queried data code Fuzzy query of

reflection ：<foreach> Tags can be queried with single conditions , Can't meet demand , Need to carry out sql The joining together of , Use LambdaQueryWrapper Conduct sql Splicing , be used or(),and() Method , But because the query is sequential ,list Query and fuzzy query are using one layer , If it's just a simple use or () Splicing words ,like Fuzzy query will be invalid , Need to put list A collection of list Packaging

solve ：
