角色权限管理

功能：用户根据其角色信息及其角色权限，实现菜单列表的动态展示

效果图：

1. 数据表信息

• 用户表

• 角色表

• 菜单表

2. 实体类

• Menu.java

public class Menu {
   
   
    private Integer m_id;

    private String m_name;

    private String m_url;

    private Integer m_state;

    private List<Role> roleList;

    @Override
    public String toString() {
   
   
        return "Menu{" +
                "m_id=" + m_id +
                ", m_name='" + m_name + '\'' +
                ", m_url='" + m_url + '\'' +
                ", m_state=" + m_state +
                ", roleList=" + roleList +
                '}';
    }
    // 省略 Getter/Setter 方法
}

• Role.java

public class Role {
   
   
    private Integer r_id;

    private String r_name;

    private Integer r_state;

    private List<Menu> menuList;

    @Override
    public String toString() {
   
   
        return "Role{" +
                "r_id=" + r_id +
                ", r_name='" + r_name + '\'' +
                ", r_state=" + r_state +
                ", roleMenus=" + roleMenus +
                ", menuList=" + menuList +
                '}';
    }
    // 省略 Getter/Setter 方法
}

• User.java

public class User {
   
   
    private Integer u_LoginName;

    private String u_password;

    private String u_trueName;

    private String u_email;

    private Integer u_state;

    private Integer r_id;

    private Role role;

    @Override
    public String toString() {
   
   
        return "User{" +
                "u_LoginName=" + u_LoginName +
                ", u_password='" + u_password + '\'' +
                ", u_trueName='" + u_trueName + '\'' +
                ", u_email='" + u_email + '\'' +
                ", u_state=" + u_state +
                ", r_id=" + r_id +
                ", role=" + role +
                '}';
    }
    // 省略 Getter/Setter 方法
}

3. Mapper 类

• RoleMapper.java

public interface RoleMapper {
   
   
    Role selectByPrimaryKey(Integer r_id);
}
