1.实体类
package com.abc.plan.domain; import com.baomidou.mybatisplus.annotation.IdType; import com.baomidou.mybatisplus.annotation.TableField; import com.baomidou.mybatisplus.annotation.TableId; import com.baomidou.mybatisplus.annotation.TableName;import lombok.*; import java.util.Date; @TableName(value = "plan_task") @Data @Builder @ToString(callSuper = true) @NoArgsConstructor @AllArgsConstructor public class PlanTask { private static final long serialVersionUID = 1L; @TableId(value = "id",type = IdType.AUTO) private Long id; @Excel(name = "名称") private String name; @Excel(name = "类型") private String type; }
2.去重
PlanTask task = PlanTask.builder().id(1).name(“abc”).type(1).build(); PlanTask task = PlanTask.builder().id(2).name(“def”).type(2).build(); PlanTask task = PlanTask.builder().id(1).name(“eee”).type(1).build(); list = list.stream().collect(Collectors.collectingAndThen(Collectors.toCollection(() -> new TreeSet<>(Comparator.comparing(PlanTask::getId))), ArrayList::new));
