2.结果实例转换类

package org.testzl.zlqtms.controller.datasource;

import java.util.List;
import java.util.function.Function;
import java.util.stream.Collectors;

public class CodeNameItemConvertor<T> {
    private List<T> list;

    public CodeNameItemConvertor(List<T> list) {
        this.list = list;
    }

    public <U> List<U> map(Function<? super T, ? extends U> converter) {
        if (list == null)
            return null;
        return list.stream().map(converter::apply).collect(Collectors.toList());
    }

}

3.使用案例

    @GetMapping("xxxxx")
    public List<CodeNameItem> tbClaimTypes(@RequestParam(required=false) String q) {
        BaseSearchViewModel baseSearchViewModel = new BaseSearchViewModel();
        baseSearchViewModel.setLimit(200);
        TbClaimType tbTrouble = new TbClaimType();
        tbTrouble.setTypeCode(q);
        tbTrouble.setCompany(userCompanyUtil.getUserCompany());
        GridResult<TbClaimType> pageListByCode = tbClaimTypeService.query(baseSearchViewModel, tbTrouble);
        return new CodeNameItemConvertor<TbClaimType>((List<TbClaimType>)pageListByCode.getBody())
                .map(p -> CodeNameItem.fromObject(p, "id", "typeCode", "descZh", "descEn"));
    }
