在分页时将其他参数传递给LazyDataModel load方法

import org.primefaces.model.LazyDataModel;
import org.primefaces.model.SortOrder;

public class CustomLazyDataModel extends LazyDataModel<Entity> {

    private String otherParam;

    public CustomLazyDataModel(String otherParam) {
        this.otherParam = otherParam;
    }

    @Override
    public List<Entity> load(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, Object> filters) {
        // 根据传递的参数进行数据查询和处理
        List<Entity> data = fetchData(first, pageSize, sortField, sortOrder, filters, otherParam);

        // 设置总行数
        int rowCount = fetchRowCount(filters, otherParam);
        this.setRowCount(rowCount);

        // 设置当前页的数据列表
        this.setWrappedData(data);

        return data;
    }

    private List<Entity> fetchData(int first, int pageSize, String sortField, SortOrder sortOrder, Map<String, Object> filters, String otherParam) {
