可以先去学习一下stream流

stream流学习

表结构建立，sql语句

这个是postgreSql 和mysql有一定的区别，注意一下！

1. 封装一个菜单的返回实体给前端

@Data
@ApiModel("菜单返回参数模型")
public class QueryMenuResp 
	@ApiModelProperty("ID")
	@JsonFormat(shape = JsonFormat.Shape.STRING)
	private Long id;
	/**
	 * 父菜单ID
	 */
	@ApiModelProperty("父菜单ID")
	@JsonFormat(shape = JsonFormat.Shape.STRING)
	private Long parentId;
	/**
	 * 菜单名
	 */
	@ApiModelProperty("菜单名")
	private String name;
	/**
	 * 菜单路径
	 */
	@ApiModelProperty("菜单路径")
	private String path;
	/**
	 * 排序
	 */
	@ApiModelProperty("排序")
	private Integer sort;
	/**
	 * 是否隐藏(1:是,0:否)
	 */
	@ApiModelProperty("是否隐藏(1:是,0:否)")
	private Integer hidden;
	/**
	 * 当前角色选中状态
	 */
	@ApiModelProperty("当前角色选中状态(1:是,0:否,仅findAvaiableMenuTree接口返回)")
	private Integer checked;
	/**
	 * 下级菜单
	 */
	@ApiModelProperty("下级菜单")
	private List<QueryMenuResp> subMenus;

2.先查询出来一级菜单，然后查询 非一级菜单进行递归调用，直到所以菜单查询出来

    @ParamCheck
    @ApiOperation(value = "查询所有菜单以树形结构返回")
    @PostMapping("/findMenuTree")
    public Result<List<QueryMenuResp>> findMenuTree(@RequestBody @ModelCheck QueryMenuParam param) 
    	log.info("findMenuTree param: ", param);
    	
    	if (!MenuBelongTo.isLegalMenuBelong(param.getBelongTo())) 
    		return Result.error("非法的菜单归属类型");
    	
    	
    	List<QueryMenuResp> allMenuList =  ModelChangeUtils.changeMenuRespList(menuService.findMenus(param.getBelongTo()));
    	// 一级菜单
    	List<QueryMenuResp> rootMenus = allMenuList.stream()
				.filter(r -> r.getParentId().equals(CommonConstant.ROOT_MENU_PARENT_ID))
				.collect(Collectors.toList());
    	// 非一级菜单
		List<QueryMenuResp> notRootMenus = allMenuList.stream()
				.filter(r -> !r.getParentId().equals(CommonConstant.ROOT_MENU_PARENT_ID))
				.collect(Collectors.toList());
		
		// 构造树形结构
		for (QueryMenuResp menu : rootMenus) 
            List<QueryMenuResp> subMenus = ModelChangeUtils.iterateMenus(notRootMenus, menu.getId());
            menu.setSubMenus(subMenus);
        
		
        return Result.succeed(rootMenus);
    

3.递归方法

public class ModelChangeUtils 
	/**
     * 多级菜单查询方法
     * @param menuList 不包含最高层次菜单的菜单集合
     * @param parentId 父菜单id
     * @return
     */
    public static List<QueryMenuResp> iterateMenus(List<QueryMenuResp> menuList, Long parentId)
        List<QueryMenuResp> result = new ArrayList<QueryMenuResp>();
        for (QueryMenuResp menu : menuList) 
            if (parentId.equals(menu.getParentId()))
                //递归查询当前子菜单的子菜单
                List<QueryMenuResp> iterateMenu = iterateMenus(menuList, menu.getId());
                menu.setSubMenus(iterateMenu);
                result.add(menu);
            
        
        return result;
    

4.菜单表结构实体

@Data
@EqualsAndHashCode(callSuper = false)
@TableName("sys_menu")
public class SysMenu extends SuperEntity<SysRole> 
	private static final long serialVersionUID = 749360940290141180L;

	/**
	 * 父菜单ID
	 */
	private Long parentId;
	/**
	 * 菜单名
	 */
	private String name;
	/**
	 * 请求地址(type=2时有效)
	 */
	private String apiUrl;
	/**
	 * 菜单路径
	 */
	private String path;
	/**
	 * 排序
	 */
	private Integer sort;
	/**
	 * 类型(1:菜单,2:按钮)
	 */
	private Integer type;
	/**
	 * 是否隐藏(1:是,0:否)
	 */
	private Integer hidden;
	/**
	 * 菜单归属(1:后台管理菜单,2:商城菜单)
	 */
	private Integer belongTo;
	
	@TableField(exist = false)
	private List<SysMenu> subMenus;

5.角色表结构实体

/**
 * 
 * 角色
 */
@Data
@EqualsAndHashCode(callSuper = false)
@TableName("sys_role")
