获取用户角色权限信息实现
提示：这里需要先把用户角色权限信息表的处理，基本的用户角色权限通过五张基础的数据表的实现，分别是 用户信息表、角色信息表、权限信息表、用户角色信息表、角色权限信息表
用户角色权限的sql初始化语句

5张数据表的如下：
- 用户信息表sys_user
- 角色信息表sys_role
- 权限信息表sys_menu
- 用户角色信息表sys_user_role
- 角色权限信息表sys_role_menu
通过MybatisX插件将对应的模块的三层接口生成
面向对象思想编程
仔细观察每个实体对象，发现多个对象中的属性【数据表的列】都是相同的
如：id、create_time、update_time、create_user、update_user、remark，所以我们可以创建一个通用基础实体类对象，
然后让其他类去继承这个基类对象即可，这样的话方便程序的维护。
基类对象BaseEntity的创建
package com.xuguoguo.entity;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import lombok.Data;
import java.io.Serializable;
import java.util.Date;
/**
* 公共基础实体类
* @author xuguoguo
*/
@Data
public class BaseEntity implements Serializable {
@TableId(value = "id", type = IdType.AUTO)
private Long id;
/**
* 创建日期
*/
@JsonSerialize(using=CustomDateTimeSerializer.class)
@JsonFormat(pattern ="yyyy-MM-dd HH:mm:ss")
private Date createTime;
/**
* 更新日期
*/
@JsonSerialize(using=CustomDateTimeSerializer.class)
@JsonFormat(pattern ="yyyy-MM-dd HH:mm:ss")
private Date updateTime;
/**
* 备注
*/
private String remark;
}
编写时间对象CustomDateTimeSerializer进行解析处理（时间需要进行处理)
package com.xuguoguo.entity;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
/**
* 自定义返回JSON 数据格式中日期格式化处理
* @author xuguoguo
*
*/
public class CustomDateTimeSerializer extends JsonSerializer<Date>{
@Override
public void serialize(Date value, JsonGenerator gen, SerializerProvider serializers)
throws IOException {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("Asia/Shanghai"));
gen.writeString(sdf.format(value));
}
}
最后在几个实体对象中先继承自BaseEntity，并将对象中的几个重复属性进行注释或者删除即可
修改自定义登录逻辑中的获取权限信息
修改common包下的MyUserDetailsServiceImpl类对象的权限列表代码
注意需要修改MyJwtAuthenticationFilter过滤器中的用户编号查询权限列表的方法
service业务层的编写
service实现类代码:
package com.xuguoguo.service;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.xuguoguo.entity.SysMenu;
import com.xuguoguo.entity.SysRole;
import com.xuguoguo.entity.SysUser;
import com.xuguoguo.mapper.SysMenuMapper;
import com.xuguoguo.mapper.SysRoleMapper;
import com.xuguoguo.service.SysUserService;
import com.xuguoguo.mapper.SysUserMapper;
import com.xuguoguo.utils.StringUtil;
import org.springframework.beans.factory.annotation.Autowired;

查询的sql演变:
分别启动服务器进行登录测试，查看控制台的用户权限是否正确
此时控制器中的请求，只要登录了就可以进行访问
请求方法上注解的使用
1、在请求方法上添加必须拥有某个角色才能请求进来的注解
@PreAuthorize("hasRole('ROLE_admin22')")
这样的话会经过全局的异常处理器进行返回【返回的数据可以自行修改哦】
2、在请求方法上添加必须拥有某个权限才能请求进来的注解
@PreAuthorize("hasAuthority('system:test:aa')")
登录页面的记住密码功能实现
实现思路
用户登录时若勾选“记住我”功能选项，则将登录名和密码（加密后）保存至本地缓存中，下次登录页面加载时自动获取保存好的账号和密码（需解密），回显到登录输入框中。
这里有三种方法来存储账号密码：
- 1.sessionStorage(不推荐)
- 1). 仅在当前会话下有效，关闭浏览器窗口后就被清除了
- 2). 存放数据大小一般为5MB
- 3). 不与服务器进行交互通信
- 2.localStorage
- 1). 除非主动清除localStorage里的信息，否则将永远存在，关闭浏览器窗口后下次启动任然存在
- 2). 存放数据大小一般为5MB
- 3). 不与服务器进行交互通信
- 3.cookies
- 1). 可以手动设置过期时间，超过有效期则失效。未设置过期时间，关闭浏览器窗口后就被清除了
- 2). 存放数据大小一般为4K
- 3). 每次请求都会被传送到服务器
早期这种功能性操作我们都是使用的cookie来保存在客户端浏览器进行存储，然后进行回显即可
这里我们需要安装依赖【js-cookie】来处理实现
存储用户密码，为了安全需要进行加密处理，获取密码解密操作，需要安装依赖【jsencrypt】
在util目录下新建jsencrypt.js
import JSEncrypt from 'jsencrypt/bin/jsencrypt.min'
// 密钥对生成 http://web.chacuo.net/netrsakeypair
const publicKey = 'MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAKoR8mX0rGKLqzcWmOzbfj64K8ZIgOdH\n' +
'nzkXSOVOZbFu/TJhZ7rFAN+eaGkl3C4buccQd/EjEsj9ir7ijT7h96MCAwEAAQ=='
const privateKey = 'MIIBVAIBADANBgkqhkiG9w0BAQEFAASCAT4wggE6AgEAAkEAqhHyZfSsYourNxaY\n' +
'7Nt+PrgrxkiA50efORdI5U5lsW79MmFnusUA355oaSXcLhu5xxB38SMSyP2KvuKN\n' +
'PuH3owIDAQABAkAfoiLyL+Z4lf4Myxk6xUDgLaWGximj20CUf+5BKKnlrK+Ed8gA\n' +
'kM0HqoTt2UZwA5E2MzS4EI2gjfQhz5X28uqxAiEA3wNFxfrCZlSZHb0gn2zDpWow\n' +
'cSxQAgiCstxGUoOqlW8CIQDDOerGKH5OmCJ4Z21v+F25WaHYPxCFMvwxpcw99Ecv\n' +
'DQIgIdhDTIqD2jfYjPTY8Jj3EDGPbH2HHuffvflECt3Ek60CIQCFRlCkHpi7hthh\n' +
'YhovyloRYsM+IS9h/0BzlEAuO0ktMQIgSPT3aFAgJYwKpqRYKlLDVcflZFCKY7u3\n' +
'UP8iWi1Qw0Y='
// 加密
export function encrypt(txt) {
const encryptor = new JSEncrypt()
encryptor.setPublicKey(publicKey) // 设置公钥
return encryptor.encrypt(txt) // 对数据进行加密
}
// 解密
export function decrypt(txt) {
const encryptor = new JSEncrypt()
encryptor.setPrivateKey(privateKey) // 设置私钥
return encryptor.decrypt(txt) // 对数据进行解密
}
在需要使用记住密码的vue页面【Login.vue】中引入
import Cookies from "js-cookie";
import { encrypt, decrypt } from "@/util/jsencrypt";
修改声明以及数据绑定
在登录处理函数中，添加逻辑代码
if (loginForm.value.rememberMe) {
//勾选了需要记住密码设置在cookkie中设置记住用户名和密码【单位是天】
Cookies.set("username", loginForm.value.username, { expires: 30 });
Cookies.set("password", encrypt(loginForm.value.password), { expires: 30 });
Cookies.set("rememberMe", loginForm.value.rememberMe, { expires: 30 });
} else {
// 否则移除
Cookies.remove("username");
Cookies.remove("password");
Cookies.remove("rememberMe");
}
添加从Cookies中获得账户和解密后密码的函数
//获取cookie的函数
function getCookie() {
const username = Cookies.get("username");
const password = Cookies.get("password");
const rememberMe = Cookies.get("rememberMe");
loginForm.value = {
username: username === undefined ? loginForm.value.username : username,
password: password === undefined ? loginForm.value.password :decrypt(password),
rememberMe: rememberMe === undefined ? false : Boolean(rememberMe)
};
}
//调用获取cookie
getCookie();
访问登录页面，在登录的时间勾选记住密码复选框，下次请求登录时可以看到已经记住了账号信息
小结
提示：本小结中主体实现的是使用数据库的用户信息实现登录，通过面向对象的编程思想实现代码的抽取base类对象以及登录页面的记住密码的实现引导处理！！！
