java实现递归菜单树
本文实例为大家分享了java实现递归菜单树的具体代码，供大家参考，具体内容如下
1.表结构
SETFOREIGN_KEY_CHECKS=0;
------------------------------
--Tablestructureformenu
------------------------------
DROPTABLEIFEXISTS`menu`;
CREATETABLE`menu`(
`id`int(11)NOTNULLAUTO_INCREMENT,
`menu_name`varchar(64)NOTNULLCOMMENT'菜单名称',
`order_num`int(11)DEFAULTNULLCOMMENT'菜单顺序',
`url`varchar(64)DEFAULTNULLCOMMENT'菜单路径',
`pid`varchar(11)DEFAULTNULLCOMMENT'上级Id',
`icon`varchar(255)DEFAULTNULLCOMMENT'菜单图标',
PRIMARYKEY(`id`)
)ENGINE=InnoDBAUTO_INCREMENT=11DEFAULTCHARSET=utf8;
------------------------------
--Recordsofmenu
------------------------------
INSERTINTO`menu`VALUES('1','系统管理','1','','0',null);
INSERTINTO`menu`VALUES('2','轨迹查询','2','','0',null);
INSERTINTO`menu`VALUES('3','设备信息','3','','0',null);
INSERTINTO`menu`VALUES('4','用户信息','1','','1',null);
INSERTINTO`menu`VALUES('5','客户信息','2',null,'1',null);
INSERTINTO`menu`VALUES('6','用户资料','1',null,'4',null);
INSERTINTO`menu`VALUES('7','客户资料','1',null,'5',null);
INSERTINTO`menu`VALUES('8','切割机','1',null,'3',null);
INSERTINTO`menu`VALUES('9','铲车','2',null,'3',null);
INSERTINTO`menu`VALUES('10','割片','1',null,'8',null);
2.菜单实体类
importlombok.Data;
importjava.io.Serializable;
importjava.util.List;
importjavax.persistence.*;
/**
*
*@authorm
*@email123456789@qq.com
*@date2019-12-1316:54:59
*/
@Data
@Table(name="menu")
publicclassMenuimplementsSerializable{
privatestaticfinallongserialVersionUID=1L;
//
@Id
privateIntegerid;
//菜单名称
@Column(name="menu_name")
privateStringmenuName;
//菜单顺序
@Column(name="order_num")
privateIntegerorderNum;
//菜单路径
@Column(name="url")
privateStringurl;
//上级Id
@Column(name="pid")
privateStringpid;
//菜单图标
@Column(name="icon")
privateStringicon;
//子菜单
@Transient
privateList
3.菜单树
/** *获取菜单树 *@return */ publicList
4.测试
{
"status":200,
"message":"操作成功",
"data":[
{
"id":1,
"menuName":"系统管理",
"orderNum":1,
"url":"",
"pid":"0",
"icon":null,
"children":[
{
"id":4,
"menuName":"用户信息",
"orderNum":1,
"url":"",
"pid":"1",
"icon":null,
"children":[
{
"id":6,
"menuName":"用户资料",
"orderNum":1,
"url":null,
"pid":"4",
"icon":null,
"children":[]
}
]
},
{
"id":5,
"menuName":"客户信息",
"orderNum":2,
"url":null,
"pid":"1",
"icon":null,
"children":[
{
"id":7,
"menuName":"客户资料",
"orderNum":1,
"url":null,
"pid":"5",

"children":[]
}
]
}
]
},
{
"id":2,
"menuName":"轨迹查询",
"orderNum":2,
"url":"",
"pid":"0",
"icon":null,
"children":[]
},
{
"id":3,
"menuName":"设备信息",
"orderNum":3,
"url":"",
"pid":"0",
"icon":null,
"children":[
{
"id":8,
"menuName":"切割机",
"orderNum":1,
"url":null,
"pid":"3",
"icon":null,
"children":[
{
"id":10,
"menuName":"割片",
"orderNum":1,
"url":null,
"pid":"8",
"icon":null,
"children":[]
}
]
},
{
"id":9,
"menuName":"铲车",
"orderNum":2,
"url":null,
"pid":"3",
"icon":null,
"children":[]
}
]
}
]
}
