• storage Java pojo and excel/csv/json automatic mapping framework, only need to define a class corresponding to Excel, directly parse Excel, json, csv

• Take advantage of the reflection nature of the Java dynamic language to parse Excel without any code

• Arrays or collections support null safe, and empty arrays or collections resolve to arrays or collections of length 0

• Empty strings are parsed to string of length 0, and empty object are parsed to null

• Support Excel to export json, csv files

• The first line of Excel corresponds to the Java class attribute, and the second and third lines do not serve as comments, where the first column must be the Id attribute

• The Java class for Excel

• In addition, you can also use the record class provided by Java's new features

• After parsing, there are two ways to use it

  1. By annotation

   @Component public class StudentManager { @ResInjection private IStorage<Integer, StudentResource> studentResources; } 

  2. Dynamically obtained through classes

  IStorage<Integer, StudentResource> studentResources = StorageContext.getStorageManager().getStorage(StudentResource.class); 

• Find the corresponding row by id

var studentResource = studentResources.get(1000); 

Alternatively, it can be obtained through the following methods

var resource = StorageContext.get(StudentResource.class, 1001); 

• Find the corresponding row by index, default to a repeatable index, and return a list

var students = studentResources.getIndex(StudentResource::getName, "james0"); 

If you are a record class, the usage is as follows

var students = studentStorage.getIndexes(StudentResource::name, "james0"); 

• The unique index is obtained through Storage.getUniqueIndex(), and the index annotation needs to be marked as @Index( unique = true)

StudentResource student = storage.getUniqueIndex(StudentResource::idCard, "110101200007281903");
