SpringBoot+Vue项目实战第二季

一、些许优化

刷新丢失其它标签页

缓存已打开标签页

tagsViewCache() {
      
      
    window.addEventListener("beforeunload", () => {
      
      
        let tabViews = this.visitedViews.map(item => {
      
      
            return {
      
      
                fullPath: item.fullPath,
                hash: item.hash,
                meta: {
      
       ...item.meta },
                name: item.name,
                params: {
      
       ...item.params },
                path: item.path,
                query: {
      
       ...item.query },
                title: item.title
            };
        });
        sessionStorage.setItem("tabViews", JSON.stringify(tabViews));
    });
    let oldViews = JSON.parse(sessionStorage.getItem("tabViews")) || [];
    if (oldViews.length > 0) {
      
      
        this.$store.state.tagsView.visitedViews = oldViews;
    }
},

在这里插入图片描述

注销时删除所有tagview

// 注销时删除所有tagview
await this.$store.dispatch('tagsView/delAllViews')
sessionStorage.removeItem('tabViews')

在这里插入图片描述

二、Swagger整合

Swagger-UI可以动态地根据注解生成在线API文档。

常用注解

@Api：用于修饰Controller类，生成Controller相关文档信息
@ApiOperation：用于修饰Controller类中的方法，生成接口方法相关文档信息
@ApiParam：用于修饰接口中的参数，生成接口参数相关文档信息
@ApiModelProperty：用于修饰实体类的属性，当实体类是请求参数或返回结果时，直接生成相关文档信息

整合步骤：

添加依赖

<!--Swagger文档工具-->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>

swagger配置类

@Configuration
@EnableOpenApi
@EnableWebMvc
public class SwaggerConfig {
      
      
    @Bean
    public Docket api() {
      
      
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.lantu"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
      
      
        return new ApiInfoBuilder()
                .title("神盾局特工管理系统接口文档")
                .description("全网最简单的SpringBoot+Vue前后端分离项目实战")
                .version("1.0")
                .contact(new Contact("qqcn", "http://www.qqcn.cn", "[email protected]"))
                .build();
    }
}

控制器根据需要添加swagger注解
测试：http://localhost:9999/swagger-ui/index.html

三、Jwt整合

JSON Web Token (JWT)是一个开放标准(RFC 7519)，它定义了一种紧凑的、自包含的方式，用于作为JSON对象在各方之间安全地传输信息。该信息可以被验证和信任，因为它是数字签名的。

jwt形式举例：

eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiI5MjAzOThjZi1hYThiLTQzNWUtOTIxYS1iNGQ3MDNmYmZiZGQiLCJzdWIiOiJ7XCJwaG9uZVwiOlwiMTIzNDIzNFwiLFwidXNlcm5hbWVcIjpcInpoYW5nc2FuXCJ9IiwiaXNzIjoic3lzdGVtIiwiaWF0IjoxNjc3MTE4Njc2LCJleHAiOjE2NzcxMjA0NzZ9.acc7H6-6ACqcgNu5waqain7th7zJciP-41z-qgWeaSY

⑴ 整合步骤

pom

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt</artifactId>
    <version>0.9.1</version>
</dependency>

工具类

@Component
public class JwtUtil {
      
      
    // 有效期
    private static final long JWT_EXPIRE = 30*60*1000L;  //半小时
    // 令牌秘钥
    private static final String JWT_KEY = "123456";

    public  String createToken(Object data){
      
      
        // 当前时间
        long currentTime = System.currentTimeMillis();
        // 过期时间
        long expTime = currentTime+JWT_EXPIRE;
        // 构建jwt
        JwtBuilder builder = Jwts.builder()
                .setId(UUID.randomUUID()+"")
                .setSubject(JSON.toJSONString(data))
                .setIssuer("system")
                .setIssuedAt(new Date(currentTime))
                .signWith(SignatureAlgorithm.HS256, encodeSecret(JWT_KEY))
                .setExpiration(new Date(expTime));
        return builder.compact();
    }

    private  SecretKey encodeSecret(String key){
      
      
        byte[] encode = Base64.getEncoder().encode(key.getBytes());
        SecretKeySpec aes = new SecretKeySpec(encode, 0, encode.length, "AES");
        return  aes;
    }

    public  Claims parseToken(String token){
      
      
        Claims body = Jwts.parser()
                .setSigningKey(encodeSecret(JWT_KEY))
                .parseClaimsJws(token)
                .getBody();
        return body;
    }

    public <T> T parseToken(String token,Class<T> clazz){
      
      
        Claims body = Jwts.parser()
                .setSigningKey(encodeSecret(JWT_KEY))
                .parseClaimsJws(token)
                .getBody();
        return JSON.parseObject(body.getSubject(),clazz);
    }

}

测试工具类
修改登录逻辑
测试登录

问题思考：

登录后续请求如何验证jwt ？

在这里插入图片描述

⑵ JWT验证拦截器

定义拦截器

@Component
@Slf4j
public class JwtValidateInterceptor implements HandlerInterceptor {
    
    
    @Autowired
    private JwtUtil jwtUtil;

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
    
    
        String token = request.getHeader("X-Token");
        System.out.println(request.getRequestURI() +" 待验证："+token);
        if(token != null){
    
    
            try {
    
    
                jwtUtil.parseToken(token);
                log.debug(request.getRequestURI() + " 放行...");
                return true;
            } catch (Exception e) {
    
    
                e.printStackTrace();
            }
        }
        log.debug(request.getRequestURI() + " 禁止访问...");
        response.setContentType("application/json;charset=utf-8");
        response.getWriter().write(JSON.toJSONString(Result.fail(20003,"jwt令牌无效，请重新登录")));
        return false;
    }
}

注册拦截器

@Configuration
public class MyWebConfig implements WebMvcConfigurer {
    
    
    @Autowired
    private JwtValidateInterceptor jwtValidateInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
    
    
        InterceptorRegistration registration = registry.addInterceptor(jwtValidateInterceptor);
        registration.addPathPatterns("/**")
                .excludePathPatterns(
                        "/user/login",
                        "/user/info",
                        "/user/logout",
                        "/error",
                        "/swagger-ui/**",
                        "/swagger-resources/**",
                        "/v3/**");
    }
}

⑶ Swagger授权配置

@Configuration
@EnableOpenApi
@EnableWebMvc
public class SwaggerConfig {
    
    
    @Bean
    public Docket api() {
    
    
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.lantu"))
                .paths(PathSelectors.any())
                .build()
                .securitySchemes(Collections.singletonList(securityScheme()))
                .securityContexts(Collections.singletonList(securityContext()));
    }

    private SecurityScheme securityScheme() {
    
    
        //return new ApiKey("Authorization", "Authorization", "header");
        return new ApiKey("X-Token", "X-Token", "header");
    }

    private SecurityContext securityContext() {
    
    
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.regex("^(?!auth).*$"))
                .build();
    }

    private List<SecurityReference> defaultAuth() {
    
    
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Collections.singletonList(
                new SecurityReference("X-Token", authorizationScopes));
    }

    private ApiInfo apiInfo() {
    
    
        return new ApiInfoBuilder()
                .title("神盾局特工管理系统接口文档")
                .description("全网最简单的SpringBoot+Vue前后端分离项目实战")
                .version("1.0")
                .contact(new Contact("老蔡", "https://space.bilibili.com/431588578", "[email protected]"))
                .build();
    }
}

⑶ 后端

RoleController

@RestController
@RequestMapping("/role")
public class RoleController {
    
    

    @Autowired
    private IRoleService roleService;

    @GetMapping("/list")
    public Result<Map<String,Object>> getUserList(@RequestParam(value = "roleName",required = false) String roleName,
                                                  @RequestParam(value = "pageNo") Long pageNo,
                                                  @RequestParam(value = "pageSize") Long pageSize){
    
    
        LambdaQueryWrapper<Role> wrapper = new LambdaQueryWrapper<>();
        wrapper.eq(StringUtils.hasLength(roleName),Role::getRoleName,roleName);
        wrapper.orderByDesc(Role::getRoleId);

        Page<Role> page = new Page<>(pageNo,pageSize);
        roleService.page(page, wrapper);

        Map<String,Object> data = new HashMap<>();
        data.put("total",page.getTotal());
        data.put("rows",page.getRecords());

        return Result.success(data);

    }

    @PostMapping
    public Result<?> addRole(@RequestBody Role role){
    
    
        roleService.save(role);
        return Result.success("新增角色成功");
    }

    @PutMapping
    public Result<?> updateRole(@RequestBody Role role){
    
    
        roleService.updateById(role);
        return Result.success("修改角色成功");
    }

    @GetMapping("/{id}")
    public Result<Role> getRoleById(@PathVariable("id") Integer id){
    
    
        Role role = roleService.getById(id);
        return Result.success(role);
    }

    @DeleteMapping("/{id}")
    public Result<Role> deleteRoleById(@PathVariable("id") Integer id){
    
    
        roleService.removeById(id);
        return Result.success("删除角色成功");

@TableField(exist = false)
@JsonInclude(JsonInclude.Include.NON_EMPTY)
private List<Menu> children;

@TableField(exist = false)
private Map<String,Object> meta = new HashMap<>();
public Map<String,Object> getMeta(){
    
    
    meta.put("title",this.title);
    meta.put("icon",this.icon);
    return this.meta;
}

MenuController

@RestController
@RequestMapping("/menu")
public class MenuController {
    
    
    @Autowired
    private IMenuService menuService;

    @GetMapping
    public Result<?> getAllMenu(){
    
    
        List<Menu> menuList =  menuService.getAllMenu();
        return Result.success(menuList);
    }

}

MenuSeviceImpl

@Override
public List<Menu> getAllMenu() {
    
    
    // 一级菜单
    LambdaQueryWrapper<Menu> wrapper = new LambdaQueryWrapper();
    wrapper.eq(Menu::getParentId,0);
    List<Menu> menuList = this.list(wrapper);
    // 子菜单
    setMenuChildren(menuList);
    return menuList;
}

private void setMenuChildren(List<Menu> menuList) {
    
    
    if(menuList != null) {
    
    
        for (Menu menu:menuList) {
    
    
            LambdaQueryWrapper<Menu> subWrapper = new LambdaQueryWrapper();
            subWrapper.eq(Menu::getParentId, menu.getMenuId());
            List<Menu> subMenuList = this.list(subWrapper);
            menu.setChildren(subMenuList);
            // 递归
            setMenuChildren(subMenuList);
        }
    }
}

3. 角色权限新增提交

⑵ 后端

在这里插入图片描述

RoleMenuMapper.xml

<?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">
<mapper namespace="com.lantu.sys.mapper.RoleMenuMapper">
    <select id="getMenuIdListByRoleId" parameterType="Integer" resultType="Integer">
        select
            a.`menu_id`
        from x_role_menu a, x_menu b
        where a.`menu_id` = b.`menu_id`
          and b.`is_leaf` = 'Y'
          and a.`role_id` = #{roleId}
    </select>
</mapper>

5. 角色权限修改提交

⑴ 后端

RoleServiceImpl新增

@Override
@Transactional
public void updateRole(Role role) {
    
    
    // 更新role表
    this.updateById(role);
    // 清除原有权限
    LambdaQueryWrapper<RoleMenu> wrapper = new LambdaQueryWrapper<>();
    wrapper.eq(RoleMenu::getRoleId,role.getRoleId());
    roleMenuMapper.delete(wrapper);
    //新增权限
    for (Integer menuId : role.getMenuIdList()) {
    
    
        roleMenuMapper.insert(new RoleMenu(null,role.getRoleId(),menuId));
    }
}

6. 角色删除时删相关权限

⑴ 后端

在这里插入图片描述

五、用户角色设置

1. 角色展示

⑴ 前端

roleManage.js

// 查询所有角色列表
getAllRole(){
    
    
    return request({
    
    
        url: '/role/all',
        method: 'get'
    });
},

5. 用户删除时删相关角色

⑴ 后端

UserServiceImpl
在这里插入图片描述

六、动态路由

1. 根据用户查询菜单

⑴ 后端

MenuMapper.xml

<select id="getMenuListByUserId" resultType="Menu">
    SELECT *
    FROM x_menu a,
    x_role_menu b,
    x_user_role c
    WHERE a.`menu_id` = b.`menu_id`
    AND b.`role_id` = c.`role_id`
    AND a.`parent_id` = #{pid}
    AND c.`user_id` = #{userId}
</select>

yml

type-aliases-package: com.lantu.*.entity

MenuMapper.java

public interface MenuMapper extends BaseMapper<Menu> {
    
    
    public List<Menu> getMenuListByUserId(@Param("userId") Integer userId,
                                          @Param("pid") Integer pid);
}

MenuServiceImpl

@Override
    public List<Menu> getMenuListByUserId(Integer userId) {
    
    
        // 一级菜单
        List<Menu> menuList = this.getBaseMapper().getMenuListByUserId(userId, 0);
        // 子菜单
        setMenuChildrenByUserId(userId, menuList);
        return menuList;
    }

    private void setMenuChildrenByUserId(Integer userId, List<Menu> menuList) {
    
    
        if (menuList != null) {
    
    
            for (Menu menu : menuList) {
    
    
                List<Menu> subMenuList = this.getBaseMapper().getMenuListByUserId(userId, menu.getMenuId());
                menu.setChildren(subMenuList);
                // 递归
                setMenuChildrenByUserId(userId,subMenuList);
            }
        }
    }

通过user/info接口返回数据

UserServiceImpl

在这里插入图片描述

2. 前端动态路由处理

⑴ 修改原路由配置

src\router\index.js，保留基础路由，其它的删掉或注释

export const constantRoutes = [
  {
    
    
    path: '/login',
    component: () => import('@/views/login/index'),
    hidden: true
  },
  {
    
    
    path: '/404',
    component: () => import('@/views/404'),
    hidden: true
  },
  {
    
    
    path: '/',
    component: Layout,
    redirect: '/dashboard',
    children: [{
    
    
      path: 'dashboard',
      name: 'Dashboard',
      component: () => import('@/views/dashboard/index'),
      meta: {
    
     title: '首页', icon: 'dashboard', affix:true ,noCache: false}
    }]
  },  
]

⑵ 获取菜单数据并保存至Vuex

src\store\modules\user.js

在这里插入图片描述

src\store\getters.js

在这里插入图片描述

⑶ 路由转换

修改src目录下的permission.js

在这里插入图片描述

import Layout from '@/layout'

// 路由转换
let myRoutes = myFilterAsyncRoutes(store.getters.menuList);
// 404
myRoutes.push({
    
    
    path: '*',
    redirect: '/404',
    hidden: true
});
// 动态添加路由
router.addRoutes(myRoutes);
// 存至全局变量
global.myRoutes = myRoutes;

next({
    
    ...to,replace:true})  // 防止刷新后页面空白

function myFilterAsyncRoutes(menuList) {
    
    
  menuList.filter(menu => {
    
    
    if (menu.component === 'Layout') {
    
    
      menu.component = Layout
      console.log(menu.component);
    } else {
    
    
      menu.component = require(`@/views/${
      
      menu.component}.vue`).default
    }
    // 递归处理子菜单
    if (menu.children && menu.children.length) {
    
    
      menu.children = myFilterAsyncRoutes(menu.children)
    }
    return true
  })
  return menuList;
}

⑷ 路由合并

src\layout\components\Sidebar\index.vue

在这里插入图片描述

测试预期结果，不同角色的用户登录后展示的菜单列表不一样。

至此，虽然实现动态菜单功能，但并没有解决安全问题，大家可以思考存在什么问题?
