EasyUI如何实现树形功能菜单
短信预约 -IT技能 免费直播动态提醒
这篇文章给大家分享的是有关EasyUI如何实现树形功能菜单的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
页面展示截图如下：
为了实现以上效果，在开始前必须先将环境配置一下。
第一步： 首先，先将 jquery-easyui-1.2.6 文件引入到工程项目下，并在jsp页面上进入引入3个jsp文件和2个css文件。如下：
<span > </span><span > </span><span ><script type="text/javascript" class="lazy" data-src="jquery-easyui-1.2.6/jquery-1.7.2.min.js"></script>
<link rel="stylesheet" type="text/css" href="jquery-easyui-1.2.6/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="jquery-easyui-1.2.6/themes/icon.css">
<script type="text/javascript" class="lazy" data-src="jquery-easyui-1.2.6/jquery.easyui.min.js"></script>
<script type="text/javascript" class="lazy" data-src="jquery-easyui-1.2.6/locale/easyui-lang-zh_CN.js"></script></span>引入顺序必须按照以上顺序引入，否则页面展示效果将出错。
第二步：引入jar包，分别为：commons-beanutils-1.8.3.jar、commons-collections-3.2.1.jar、commons-lang-2.5.jar、commons-logging-1.1.1.jar、ezmorph-1.0.6.jar、json-lib-2.3-jdk15.jar、mysql-connector-java-5.1.17-bin.jar
代码实现
1、创建数据表
<span >drop database easyui;
create database easyui;
use easyui;
show tables;
#创建菜单表
create table menu(
id int(11) not null auto_increment, ####菜单id###
name varchar(20) default null, ####菜单名####
url varchar(100) default null, #### 菜单url####
checked varchar(10) default null, ####菜单是否被选中
icon varchar(30) default null, ####菜单图标####
parent_id int(11) default null, ####父节点菜单的id####
primary key(id) ####id是主键####
);
#插入测试数据 ####测试数据####
insert into menu(id,name,url,checked,icon,parent_id) values
(1,'权限菜单',null,'',null,0),
(2,'用户管理',null,'0',null,1),
(3,'岗位管理',null,'',null,1),
(4,'资源管理',null,'',null,1),
(5,'用户功能1',null,'',null,2),
(6,'岗位功能1',null,'0',null,3),
(7,'资源功能2','/easyui/index.jsp','0',null,3),
(8,'资源功能1','sss','0',null,4),
(9,'岗位功能2',null,'',null,3),
(10,'资源功能3','111','0',null,4),
(11,'资源管理4','222','',null,4),
(14,'岗位功能3','dfds',null,null,3),
(17,'用户功能2','sss','0',null,2);
#查看数据
select * from menu;
//查询跟节点
select * from menu where parent_id=0;
#查看指定父节点下有哪些子节点
select * from menu where parent_id=2;</span><span >
</span>2、JDBC连接工具类
JDBCUtils.Java
<span >package com.hsj.utils;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class JDBCUtils {
static {
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
public static Connection getConnection() throws Exception {
return DriverManager.getConnection(
"jdbc:mysql:///easyui?useUnicode=true&characterEncoding=UTF-8",
"root", "zxczxc");
}
public static void close(ResultSet rs, PreparedStatement ps, Connection conn) {
try {
if (rs != null)
rs.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (ps != null)
ps.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (conn != null)
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
}</span><span >
</span>3、创建实体类domain
Menu.java
<span >package com.hsj.domain;
public class Menu {
private int id; //菜单id
private String name; //菜单名
private String url; //菜单链接的网址
private String checked; //菜单是否被选中
private String icon; //菜单图标
private int parent_id; //当前菜单的父节点id
public Menu(){}
public Menu(int id, String name, String url, String checked, String icon,int parentId) {
this.id = id;
this.name = name;
this.url = url;
this.checked = checked;
this.icon = icon;
parent_id = parentId;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public String getChecked() {
return checked;
}
public void setChecked(String checked) {
this.checked = checked;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}
public int getParent_id() {
return parent_id;
}
public void setParent_id(int parentId) {
parent_id = parentId;
}
}
</span>TreeDTD.java
<span >package com.hsj.domain;
import java.util.HashMap;
import java.util.Map;
public class TreeDTO {
private int id;
private String text;
private String iconCls;
private String checked;
private int parent_id;
private String state;
private Map<String, Object> attributes = new HashMap<String, Object>();
public TreeDTO() {
}
public TreeDTO(int id, String text, String iconCls, String checked,
int parent_id, String state, Map<String, Object> attributes) {
this.id = id;
this.text = text;
this.iconCls = iconCls;
this.checked = checked;
this.parent_id = parent_id;
this.state = state;
this.attributes = attributes;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public String getIconCls() {
return iconCls;
}
public void setIconCls(String iconCls) {
this.iconCls = iconCls;
}
public String getChecked() {
return checked;
}
public void setChecked(String checked) {
this.checked = checked;
}
public int getParent_id() {
return parent_id;
}
public void setParent_id(int parentId) {
parent_id = parentId;
}
public String getState() {
return state;
}
public void setState(String state) {
this.state = state;
}
public Map<String, Object> getAttributes() {
return attributes;
}
public void setAttributes(Map<String, Object> attributes) {
this.attributes = attributes;
}
@Override
public String toString() {
return "TreeDTO [attributes=" + attributes + ", checked=" + checked
+ ", iconCls=" + iconCls + ", id=" + id + ", parent_id="
+ parent_id + ", state=" + state + ", text=" + text + "]";
}
}
</span>4、创建接口DAO
MeunDao.java
<span >package com.hsj.dao;
import java.util.List;
import com.hsj.domain.Menu;
import com.hsj.domain.TreeDTO;
public interface MenuDao{
public List<TreeDTO> getChildrenByParentId(String parentId);
public Menu findMenuById(int id);
public <T> void save(T t);
public void update(Menu menu);

}
</span>5、实现DAO接口方法Bean
