# 菜单管理 #

在上一章节我们已经实现了字典管理，在本章我们则需要实现我们的菜单管理。

## 相关工具类的实现 ##

在我们开始编写菜单管理的时候我们首先需要实现一些相关工具类，例如菜单映射的mapper、菜单的组装工具类等。

### TreeDto【实体转换类】 ###

在core目录底下创建一个TreeDto，用于作为返回给前端加载菜单的实体，代码如下：

package com.github.bg.admin.core.dto;
    
    import java.util.List;
    
    /**
     * @author linzf
     * @since 2019/5/5
     * 类描述：前端展示菜单的dto实体
     */
    public class TreeDto {
    
        /**
         * 菜单流水ID
         */
        private Integer treeId;
        /**
         * 菜单名字
         */
        private String title;
    
        /**
         * 菜单编码
         */
        private String treeCode;
        /**
         * 菜单状态【1：可用；2：禁用】
         */
        private String treeState;
        /**
         * 菜单类型【1：菜单节点；2：按钮节点】
         */
        private String treeType;
        /**
         * 父节点唯一标识
         */
        private Integer parentTreeId;
        /**
         * 父节点名字
         */
        private String parentTreeName;
        /**
         * 默认子节点都是展开的
         */
        private boolean expand = true;
        /**
         * 默认节点是没有选中的
         */
        private boolean checked = false;
        /**
         * 子节点数据
         */
        private List<TreeDto> children;
    
        public Integer getTreeId() {
            return treeId;
        }
    
        public void setTreeId(Integer treeId) {
            this.treeId = treeId;
        }
    
        public String getTitle() {
            return title;
        }
    
        public void setTitle(String title) {
            this.title = title;
        }
    
        public String getTreeCode() {
            return treeCode;
        }
    
        public void setTreeCode(String treeCode) {
            this.treeCode = treeCode;
        }
    
        public String getTreeState() {
            return treeState;
        }
    
        public void setTreeState(String treeState) {
            this.treeState = treeState;
        }
    
        public String getTreeType() {
            return treeType;
        }
    
        public void setTreeType(String treeType) {
            this.treeType = treeType;
        }
    
        public Integer getParentTreeId() {
            return parentTreeId;
        }
    
        public void setParentTreeId(Integer parentTreeId) {
            this.parentTreeId = parentTreeId;
        }
    
        public String getParentTreeName() {
            return parentTreeName;
        }
    
        public void setParentTreeName(String parentTreeName) {
            this.parentTreeName = parentTreeName;
        }
    
        public boolean isExpand() {
            return expand;
        }
    
        public void setExpand(boolean expand) {
            this.expand = expand;
        }
    
        public boolean isChecked() {
            return checked;
        }
    
        public void setChecked(boolean checked) {
            this.checked = checked;
        }
    
        public List<TreeDto> getChildren() {
            return children;
        }
    
        public void setChildren(List<TreeDto> children) {
            this.children = children;
        }
    }

### TreeMapper【菜单实体转换】 ###

package com.github.bg.admin.core.mapper;
    
    
    import com.github.bg.admin.core.dto.TreeDto;
    import com.github.bg.admin.core.entity.Tree;

    import org.mapstruct.Mappings;
    
    import java.util.List;
    
    /**

     * @since 2019/5/5
     * 类描述：菜单实体快速转换的实现
     */
    @Mapper(componentModel = "spring")
    public interface TreeMapper {
    
        /**
         * 功能描述：实现数据的转换
         *
         * @param entity
         * @return
         */
        @Mappings({
                @Mapping(target = "title", source = "treeName"),
                @Mapping(target = "treeId", source = "treeId")
        })
        TreeDto treeToTreeDto(Tree entity);
    
        /**
         * 功能描述：实现集合的数据的转换，这边先设置实体之间的转换集合的设置才会实现
         *

         */
        List<TreeDto> treesToTreeDTO(List<Tree> trees);
    
    }

### TreeInstall【菜单组装工具类】 ###

                    if(treeMap.get(tree.getTreeId().toString())!=null){
                        tree.setChecked(true);
                    }else{
                        tree.setChecked(false);

### TreeStaticConstant菜单静态类 ###

package com.github.bg.admin.core.constant;
    
    /**
     * @author linzf
     * @since 2019/5/5
     * 类描述：
     */
    public class TreeStaticConstant {
    
        /**
         * 菜单状态为正常
         */
        public static final String TREE_STATE_NORMAL = "1";
    
        /**
         * 菜单类型为菜单节点
         */
        public static final String TREE_TYPE_MENU = "1";
    
        /**
         * 菜单类型为按钮节点
         */
        public static final String TREE_TYPE_BUTTON = "2";
    
    
        /**
         * 验证是否通过的标识
         */
        public static final String CHECK_TREE_TIP = "success";
    
        /**
         * 验证通过
         */
        public static final String CHECK_TREE_PASS = "pass";
    
        /**
         * 验证不通过
         */
        public static final String CHECK_TREE_UN_PASS = "unPass";
    
    }

## 菜单管理的实现 ##

由于菜单是和角色是相互关联的，因此当我们在删除菜单的时候，我们应该同时需要删除二者之间的关联关系，因此我们在此处需要实现根据菜单ID来删除菜单和角色的关联关系的方法。

### RoleTreeDao.xml代码实现如下 ###

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

        <result column="roleId" jdbcType="VARCHAR" property="roleId" />
        <result column="treeId" jdbcType="INTEGER" property="treeId" />
      </resultMap>
    
      
      <delete id="deleteRoleTreeByTreeId">
        delete from t_role_tree where treeId = #{treeId}

    public interface RoleTreeDao extends Mapper<RoleTree> {
    
        /**
         * 功能描述：根据菜单ID删除关联关系
         * @param treeId 菜单ID

### 前端本章缺失 ###

由于前端的部分在菜单管理章节有部分缺失因此，此处就不再累述了，已经把代码整合到本章中了，大家直接从本章的代码地址拷贝代码下来即可，拷贝的位置如下：  
![在这里插入图片描述][2019070814480299.png]

## 运行项目 ##

最后我们重新编译我们的项目，记得一定要重新编译，因为我们引入了mapper，不重新编译是会报错的，然后我们使用账号：admin密码：123456登录系统操作我们的菜单模块，可以正常的对整个菜单模块进行相应的操作，这样我们就完成了菜单的整合。
