数组与数组之间过滤 import { cloneDeep, uniqBy, concat, every, filter } from 'lodash'; let usersList = cloneDeep(this.usersList.items); usersList = filter(usersList, d => every(this.users, v => v.node !== d.node)); this.usersList.items =SpringMVC---获得请求数据
请求参数格式：name=value&name=value… 基本类型 Controller业务方法的参数名称与请求参数name一致的话，参数值将会自动映射。 @RequestMapping("/quick8") @ResponseBody public int save8(String username){ System.out.println(username); Users useJava8对多个字段排序
Java8对多个字段排序 创建User对象 public class Users { private Long id; private String name; private String code; private Long supId; private List<Users> usersList; public Users() { } public Users(Long id, String name, StringJava8将List对象转换Map
基于Java8的函数式编程概念，去实现List<Object>转换Map<String,Object> public class DemoMian2 { public static void main(String[] args) { List<Users> usersList = new ArrayList(); Users users = new Users(); users.setId(1L);
