解决springboot+vue静态资源刷新后无法访问的问题-编程知识

一、背景

原项目是有前后端分离设计，测试环境是centos系统，采用nginx代理和转发，项目正常运行。
项目近期上线到正式环境，结果更换了系统环境，需要放到一台windows系统中，前后端打成一个jar包，然后做成系统服务。这台服务器中已经有很多其他服务，都是采用一样的部署方式，所以没办法只能对这个项目进行修改。

二、修改过程

2.1 首先看项目结构

在这里插入图片描述
admin是后端代码，使用的是springboot，使用 spring security 权限控制；UI是前端，使用的是vue3+vite

admin的结构

ui的结构

2.2 打包静态资源

修改前端打包配置vite.config.js

import { defineConfig, loadEnv } from 'vite'
import path from 'path'
import createVitePlugins from './vite/plugins'// https://vitejs.dev/config/
export default defineConfig(({ mode, command }) => {const env = loadEnv(mode, process.cwd())const { VITE_APP_ENV } = envreturn {// 部署生产环境和开发环境下的URL。// 默认情况下，vite 会假设你的应用是被部署在一个域名的根路径上base: VITE_APP_ENV === 'production' ? '/' : '/',build: {outDir: '../admin/src/main/resources/static'},plugins: createVitePlugins(env, command === 'build'),resolve: {// https://cn.vitejs.dev/config/#resolve-aliasalias: {// 设置路径'~': path.resolve(__dirname, './'),// 设置别名'@': path.resolve(__dirname, './src')},// https://cn.vitejs.dev/config/#resolve-extensionsextensions: ['.mjs', '.js', '.ts', '.jsx', '.tsx', '.json', '.vue']},// vite 相关配置server: {port: 888,host: true,open: true,proxy: {// https://cn.vitejs.dev/config/#server-proxy'/': {target: 'http://localhost:8080',changeOrigin: true,// rewrite: (p) => p.replace(/^\/api/, '')}}},//fix:error:stdin>:7356:1: warning: "@charset" must be the first rule in the filecss: {postcss: {plugins: [{postcssPlugin: 'internal:charset-removal',AtRule: {charset: (atRule) => {if (atRule.name === 'charset') {atRule.remove();}}}}]}}}
})

增加下面代码

build: {outDir: '../admin/src/main/resources/static'
},

指定编译后的静态文件存放目录，默认的是在ui/dist目录，然后执行生产环境打包命令 npm run prod / npm run build，成功后会在admin/resource目录下生成一个static文件夹

同时，把前端路径与后端路径冲突的修改一下。

2.3 修改后端权限控制

修改SecurityConfig，增加静态资源的访问权限

/*** spring security配置** @author admin*/
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {/*** 自定义用户认证逻辑*/@Resourceprivate UserDetailsService userDetailsService;/*** 认证失败处理类*/@Resourceprivate AuthenticationEntryPointImpl unauthorizedHandler;/*** 退出处理类*/@Resourceprivate LogoutSuccessHandlerImpl logoutSuccessHandler;/*** token认证过滤器*/@Resourceprivate JwtAuthenticationTokenFilter authenticationTokenFilter;/*** 跨域过滤器*/@Resourceprivate CorsFilter corsFilter;/*** 允许匿名访问的地址*/@Resourceprivate PermitAllUrlProperties permitAllUrl;/*** 鉴权*/@Overrideprotected void configure(HttpSecurity httpSecurity) throws Exception {// 注解标记允许匿名访问的urlExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry = httpSecurity.authorizeRequests();permitAllUrl.getUrls().forEach(url -> registry.antMatchers(url).permitAll());httpSecurity// CSRF禁用，因为不使用session.csrf().disable()// 禁用HTTP响应标头.headers().cacheControl().disable().and()// 认证失败处理类.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()// 基于token，所以不需要session.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()// 过滤请求.authorizeRequests()// 对于登录login 验证码captchaImage 允许匿名访问.antMatchers("/login", "/sendSmsCode/*", "/captchaImage").permitAll()// 静态资源，可匿名访问.antMatchers(HttpMethod.GET, "/", "/*.html", "/*.html.gz", "/assets/**", "/favicon.ico", "/profile/**").permitAll().antMatchers("/webjars/**", "/druid/**").permitAll()// 除上面外的所有请求全部需要鉴权认证.anyRequest().authenticated().and().headers().frameOptions().disable();// 添加Logout filterhttpSecurity.logout().logoutUrl("/logout").logoutSuccessHandler(logoutSuccessHandler);// 添加JWT filterhttpSecurity.addFilterBefore(authenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);// 添加CORS filterhttpSecurity.addFilterBefore(corsFilter, JwtAuthenticationTokenFilter.class);httpSecurity.addFilterBefore(corsFilter, LogoutFilter.class);}
}

静态文件处理类ResourcesConfig

@Configuration
public class ResourcesConfig implements WebMvcConfigurer {@Resourceprivate RepeatSubmitInterceptor repeatSubmitInterceptor;@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {/** 本地文件上传路径，FileConfig.getPath() 为本地磁盘目录 */registry.addResourceHandler("/profile/**").addResourceLocations("file:" + FileConfig.getPath() + "/");/** 静态资源 */registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");}/*** 自定义拦截规则*/@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(repeatSubmitInterceptor).addPathPatterns("/**");}/*** 跨域配置*/@Beanpublic CorsFilter corsFilter() {CorsConfiguration config = new CorsConfiguration();config.setAllowCredentials(true);// 设置访问源地址config.addAllowedOriginPattern("*");// 设置访问源请求头config.addAllowedHeader("*");// 设置访问源请求方法config.addAllowedMethod("*");// 有效期 1800秒config.setMaxAge(1800L);// 添加映射路径，拦截一切请求UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();source.registerCorsConfiguration("/**", config);// 返回新的CorsFilterreturn new CorsFilter(source);}
}

认证失败处理类AuthenticationEntryPointImpl，解决退出成功后无法跳转到登录页的问题


/*** 认证失败处理类 返回未授权** @author admin*/
@Slf4j
@Component
public class AuthenticationEntryPointImpl implements AuthenticationEntryPoint, Serializable {private static final long serialVersionUID = -8970718410437077606L;/*** 向调用者提供有关哪些HTTP端口与系统上的哪些HTTPS端口相关联的信息*/private PortMapper portMapper = new PortMapperImpl();/*** 端口解析器，基于请求解析出端口*/private PortResolver portResolver = new PortResolverImpl();/*** 登陆页面URL*/private String loginFormUrl;/*** 默认为false，即不强制Https转发或重定向*/private boolean forceHttps = false;/*** 默认为false，即不是转发到登陆页面，而是进行重定向*/private boolean useForward = false;/*** 重定向策略*/private final RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();public String getLoginFormUrl() {return loginFormUrl;}public void setLoginFormUrl(String loginFormUrl) {this.loginFormUrl = loginFormUrl;}/*** 允许子类修改成适用于给定请求的登录表单URL*/protected String determineUrlToUseForThisRequest(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) {return getLoginFormUrl();}@Overridepublic void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {String redirectUrl = null;if (useForward) {if (forceHttps && HttpScheme.HTTP.name().equals(request.getScheme())) {redirectUrl = buildHttpsRedirectUrlForRequest(request);}if (redirectUrl == null) {String loginForm = determineUrlToUseForThisRequest(request, response, authException);RequestDispatcher dispatcher = request.getRequestDispatcher(loginForm);dispatcher.forward(request, response);return;}} else {redirectUrl = buildRedirectUrlToLoginPage(request, response, authException);}redirectStrategy.sendRedirect(request, response, redirectUrl);}/*** 构建重定向URL** @param request* @param response* @param authException* @return*/protected String buildRedirectUrlToLoginPage(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) {// 通过determineUrlToUseForThisRequest方法获取URLString loginForm = determineUrlToUseForThisRequest(request, response, authException);// 如果是绝对URL，直接返回if (UrlUtils.isAbsoluteUrl(loginForm)) {return loginForm;}// 如果是相对URL// 构造重定向URLint serverPort = portResolver.getServerPort(request);String scheme = request.getScheme();RedirectUrlBuilder urlBuilder = new RedirectUrlBuilder();urlBuilder.setScheme(scheme);urlBuilder.setServerName(request.getServerName());urlBuilder.setPort(serverPort);urlBuilder.setContextPath(request.getContextPath());urlBuilder.setPathInfo(loginForm);if (forceHttps && HttpScheme.HTTP.name().equals(scheme)) {Integer httpsPort = portMapper.lookupHttpsPort(serverPort);if (httpsPort != null) {// 覆盖重定向URL中的scheme和porturlBuilder.setScheme("https");urlBuilder.setPort(httpsPort);} else {log.warn("Unable to redirect to HTTPS as no port mapping found for HTTP port " + serverPort);}}return urlBuilder.getUrl();}/*** 构建一个URL以将提供的请求重定向到HTTPS* 用于在转发到登录页面之前将当前请求重定向到HTTPS*/protected String buildHttpsRedirectUrlForRequest(HttpServletRequest request) throws IOException, ServletException {int serverPort = portResolver.getServerPort(request);Integer httpsPort = portMapper.lookupHttpsPort(serverPort);if (httpsPort != null) {RedirectUrlBuilder urlBuilder = new RedirectUrlBuilder();urlBuilder.setScheme("https");urlBuilder.setServerName(request.getServerName());urlBuilder.setPort(httpsPort);urlBuilder.setContextPath(request.getContextPath());urlBuilder.setServletPath(request.getServletPath());urlBuilder.setPathInfo(request.getPathInfo());urlBuilder.setQuery(request.getQueryString());return urlBuilder.getUrl();}// 通过警告消息进入服务器端转发log.warn("Unable to redirect to HTTPS as no port mapping found for HTTP port " + serverPort);return null;}/*** 设置为true以强制通过https访问登录表单* 如果此值为true（默认为false），并且触发拦截器的请求还不是https* 则客户端将首先重定向到https URL，即使serverSideRedirect（服务器端转发）设置为true*/public void setForceHttps(boolean forceHttps) {this.forceHttps = forceHttps;}/*** 是否要使用RequestDispatcher转发到loginFormUrl，而不是302重定向*/public void setUseForward(boolean useForward) {this.useForward = useForward;}
}

增加一个刷新跳转处理类 ServletConfig，很关键。这个方案由博主 @云散不过浅浅一下（原出处https://blog.csdn.net/twinkle2star/article/details/105191782）提供

@Configuration
public class ServletConfig {@Beanpublic WebServerFactoryCustomizer<ConfigurableWebServerFactory> webServerFactoryCustomizer() {return factory -> {// 404时跳转到首页ErrorPage errorPage = new ErrorPage(HttpStatus.NOT_FOUND, "/index.html");factory.addErrorPages(errorPage);};}
}

修改一下TokenService类，增加从前端页面请求中获取Cookie，并且获取token

/*** 获取用户身份信息** @return 用户信息*/
public LoginUser getLoginUser(HttpServletRequest request) {// 获取请求携带的令牌String token = getToken(request);if (StringUtils.isBlank(token)) {// 增加从前端页面请求中获取Cookie，并且获取tokenCookie cookie = Arrays.stream(request.getCookies()).filter(item -> "Admin-Token".equals(item.getName())).findFirst().orElse(null);if (cookie != null) {token = cookie.getValue();}}if (StringUtils.isNotEmpty(token)) {try {Claims claims = parseToken(token);// 解析对应的权限以及用户信息，Constants.LOGIN_USER_KEY为自定义redis keyString uuid = (String) claims.get(Constants.LOGIN_USER_KEY);String userKey = getTokenKey(uuid);return redisCache.getCacheObject(userKey);} catch (Exception e) {}}return null;
}
