list转换

?

1 2 3 4 5 6 7 8 9 10 11

List<SysDept> deptTrees; deptTrees.stream().map(TreeSelect::new).collect(Collectors.toList()); TreeSelect是需要转换的list public TreeSelect(SysDept dept)     {         this.id = dept.getDeptId(); //        this.level = dept.getLevel();         this.label = dept.getDeptName();         this.status = dept.getStatus();         this.fbfbm = dept.getFbfbm();     }

　　

TreeSelect中新建构造方法。把需要复制的属性一一赋值。
