Some of the names of database fields are uppercase, some are lowercase, and we often use List<Map<String, Object> when querying records from the database in java programs > to store the obtained database records, when using it, for the robustness of the program, it is often recycled, and then the key of the map is changed to uppercase or all to lowercase, which not only writes a lot of code, but also makes the originally uncomplicated program obscure and reduces the performance of the program. If this is the case, it will be much more convenient when using it in the program. The LinkedCaseInsensitiveMap introduced this time is this. The LinkedCaseInsensitiveMap class is located under the org.springframework.util.LinkedCaseInsensitiveMap package and is a tool class provided by spring. Here is the test procedure:
