1，首先要有tld文件标签文件：这里借鉴前辈，直接上代码。。

<?xml version="1.0" encoding="UTF-8"?>

这个文件的后缀名是；expend-tag.tld这是我定义的。（可以任意修改）

2，把tld文件上面的对应的类（处理标签类建立起来。）

}

3，select标签对应的有一个实体类，tree对应的一个实体类

（1）select实体类

package pro.entity;

public class UIComponentBean {
    private String key;
    private String value;

    public UIComponentBean()
    {
    }
    public UIComponentBean(String key,String value)
    {
        this.key = key;
        this.value = value;
    }
    
    
    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

（2）tree实体类

package pro.utils.basebean;

import java.util.List;

public class UITreeBean {
    private String id;
    private String pId;
    private String name;
    private boolean isParent=false;
    private boolean open=false;
    private List<UITreeBean> children;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getpId() {
        return pId;
    }

    public void setpId(String pId) {
        this.pId = pId;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public boolean isParent() {
        return isParent;
    }

    public void setParent(boolean isParent) {
        this.isParent = isParent;
    }

    public boolean isOpen() {
        return open;
    }

    public void setOpen(boolean open) {
        this.open = open;
    }

    public List<UITreeBean> getChildren() {
        return children;
    }

    public void setChildren(List<UITreeBean> children) {
        this.children = children;
    }

}

4，然后就直接上DBHeper类了，提供数据源的以及，tree标签定义的递归（我这里都是手动封装数据源，没有真正连接数据库）

5，我这里有个json工具类，用到了一点，也贴出来了。

7，如果是springmvc好像要在web.xml里面加入你tld标签的引用(我这里工程建的单纯，就一个sturts2就不需要了)；这里少Action类，（忘记了）这里也一并贴出来

<jsp-config>
    <taglib>       
     <taglib-uri>tlds/expend-tag.tld</taglib-uri>

    public String getList()
    {
        HttpServletRequest request = ServletActionContext.getRequest();
        List<UIComponentBean> list = new ArrayList<UIComponentBean>();

    }
    
    public String Select()
    {

        HttpServletRequest request = ServletActionContext.getRequest();
        String selectName = request.getParameter("selectName");

    public EmployeeQueryVO getEmployeeQueryVO() {
        return employeeQueryVO;
    }

    public void setEmployeeQueryVO(EmployeeQueryVO employeeQueryVO) {
        this.employeeQueryVO = employeeQueryVO;
    }

}

struts.xml就不用贴了相信大家都会。

　8，我贴出一些我这个标签操作文档

标签使用说明文档

1.数据准备

(1)如果是类别字典，请在TYPE_DICTIONARY表中进行录入数据，详细说明请参考Repositories\minxinloan\branches\doc\01开发文档\数据库设计\系统类别字典导入模版.xlsx

(2)如果是外键或者树结构，请手动在SYSTEM_CODE_CACHE表中进行配置。

SYSTEM_CODE_CACHE建表脚本请参见Repositories\minxinloan\branches\doc\01开发文档\数据库设计\公用表(SYSTEM_CODE_CACHE)Sql创建脚本.txt

SYSTEM_CODE_CACHE表字段说明

ID	表的主键，录入数据的时候不重复就可以了
CODE	不能重复的编码，不仅在本表中不能重复，要求与TYPE_DICTIONARY表里面的TYPE_CODE字段的记录也不能重复
NAME	当前查询的描述信息
LIST_SQL	1.查询的sql语句，要求能在plsql上面执行成功，不报错。 2.如果查询的是树结构的数据，要求按照id，上级id，树结构显示的name进行select，并且查询语句查询的结果集第一条数据是根节点，请对sql做好排序。 3.Sql里面可以带有参数，请用？标识。
IS_CACHED	设置是否缓存，外键表的数据建议不要缓存，以免查询到的数据不能及时更新，0表示不缓存，1表示缓存

2.标签使用说明

(1).exp:select标签，可配置的属性有：

code	对应要查询的UC_TYPE_DICTIONARY表里面的TYPE_CODE或者SYSTEM_CODE_CACHE表里面的CODE
params	如果查询语句里面有参数，传入的参数就配置在这里
id	select标签的唯一标识
name	标签的名称
headerKey	标签初始化时候的值
headerValue	标签初始化时候显示的文本
value	标签的值
cssClass	标签的样式
style	标签的样式，例如设置width
onChange	设置选择不同的值触发的事件
disabled	设置为true标识标签不可用
dataType	设置成Require表示改项必须选择
msg	为空的时候提示信息

使用例子：<exp:select code="EMPLOYEE_LIST" name="q_name" value="100"/>

(2) exp:radio标签，可配置的属性有：

code	对应要查询的UC_TYPE_DICTIONARY表里面的TYPE_CODE或者SYSTEM_CODE_CACHE表里面的CODE
params	如果查询语句里面有参数，传入的参数就配置在这里
name	标签的名称
value	标签的值
onChange	设置选择不同的值触发的事件
disabled	设置为true标识标签不可用
onClick	点击标签的时候触发的事件
colCount	每行显示的标签个数，默认显示5个

使用例子：<exp:radio code="EMPLOYEE_LIST" name="user" value="101"/>

(3) exp:checkboxlist标签，可配置的属性有：

code	对应要查询的UC_TYPE_DICTIONARY表里面的TYPE_CODE或者SYSTEM_CODE_CACHE表里面的CODE
params	如果查询语句里面有参数，传入的参数就配置在这里
name	标签的名称
value	标签的值, 多个值中间用,分开
onChange	设置选择不同的值触发的事件
disabled	设置为true标识标签不可用
onClick	点击标签的时候触发的事件
colCount	每行显示的标签个数，默认显示5个

使用例子：<exp:checkboxlist code="PWD_DATE" name="pwd_date" value="3,12"/>

(4) exp:tree标签，可配置的属性有：

code	对应要查询的UC_TYPE_DICTIONARY表里面的TYPE_CODE或者SYSTEM_CODE_CACHE表里面的CODE
params	如果查询语句里面有参数，传入的参数就配置在这里
id	树控件的id
checkStyle	设置显示的树是否需要checkbox或者radio
onChange	设置选择不同的值触发的事件
chkboxType	配置格式{‘Y‘:‘p‘,‘Y‘:‘s‘}。配置项说明，Y 属性定义 checkbox 被勾选后的情况； N 属性定义 checkbox 取消勾选后的情况； "p" 表示操作会影响父级节点； "s" 表示操作会影响子级节点。请注意大小写，不要改变
onClick	点击树节点触发的事件，配置的时候只需配置function的名称，不要跟括号。回调函数格式： function treeClick(event,treeId,node){ //…… }
expendLevel	树加载完展开的级数，默认展开3级
value	树选中的值, 多个值中间用,分开
style	列表树显示的样式，可以通过style设置树形显示的大小，默认为width:200px;height:300px;
rootNodeId	虚拟的根节点id
rootNodeName	虚拟的根节点名称

使用例子:<exp:tree code="ORGAN_TREE" onClick="treeClick" checkStyle="checkbox" chkboxType="{‘Y‘:‘p‘,‘Y‘:‘s‘}"></exp:tree>

注：使用树控件需要引入<link rel="stylesheet" href="${ctxStatic}/jquery-ztree/3.5.12/css/zTreeStyle/zTreeStyle.css" type="text/css">

如果树需要配置checkbox，还需要引入

对于树控件的其他操作，请参见项目\minxinloan\src\main\webapp\static\jquery-ztree\3.5.12\api

(5) exp:treeSelect标签，可配置的属性有：

code	对应要查询的UC_TYPE_DICTIONARY表里面的TYPE_CODE或者SYSTEM_CODE_CACHE表里面的CODE
params	如果查询语句里面有参数，传入的参数就配置在这里
id	树控件的id
checkStyle	设置显示的树是否需要checkbox或者radio
onChange	设置选择不同的值触发的事件
chkboxType	配置格式{‘Y‘:‘p‘,‘Y‘:‘s‘}。配置项说明，Y 属性定义 checkbox 被勾选后的情况； N 属性定义 checkbox 取消勾选后的情况； "p" 表示操作会影响父级节点； "s" 表示操作会影响子级节点。请注意大小写，不要改变
onClick	点击树节点触发的事件，配置的时候只需配置function的名称，不要跟括号。回调函数格式： function treeClick(event,treeId,node){ //…… }
expendLevel	树加载完展开的级数，默认展开3级
value	树选中的值, 多个值中间用,分开
style	列表树显示的样式，可以通过style设置树形显示的大小，默认为width:200px;height:300px;
rootNodeId	虚拟的根节点id
rootNodeName	虚拟的根节点名称
dataType	设置成Require表示改项必须选择
msg	为空的时候提示信息
name	控件的名称

使用例子: <exp:treeSelect name="parentId" code="MODULE_TREE" expendLevel="3" value="${module.parentId}"

dataType="Require" msg="上级模块不能为空！" />

注：使用树控件需要引入<link rel="stylesheet" href="${ctxStatic}/jquery-ztree/3.5.12/css/zTreeStyle/zTreeStyle.css" type="text/css">

需要引入样式

如果树需要配置checkbox，还需要引入

对于树控件的其他操作，请参见项目\minxinloan\src\main\webapp\static\jquery-ztree\3.5.12\api
