我有这个Scala方法,错误如下.无法转换为Scala列表.

 def findAllQuestion():List[Question]={
   questionDao.getAllQuestions()
 } 

类型不匹配; 发现:java.util.List[com.aitrich.learnware.model.domain.entity.Question]必填: scala.collection.immutable.List[com.aitrich.learnware.model.domain.entity.Question]

'<button id="'+item['id']+'" class="btnDeactivateKeyInChildPremiumCustomer waves-effect waves-light>ok</button>'

我使用上面的代码在jquery里面生成每个函数的按钮.动态创建按钮,当我点击按钮时,它应该显示按钮上的进度.我正在使用这款Ladda Button Loader.

    btnDeactivateKeyInChildPremiumCustomerClick : function(event){
        var id = event.currentTarget.id;
        var btnProgress = Ladda.create(document.querySelector('#'+id));
//btnProgress.start(); or //btnProgress.stop();
    }

然后我通过按钮事件处理程序捕获事件处理上面的函数.在该函数中它将创建一个btnProgress对象.之后我可以调用start()或stop()函数.我只在一个按钮的情况下成功地工作,而不是在每个按钮内动态创建按钮.但是在每种情况下,它在执行var btnProgress = Ladda.create(document.querySelector('#'+ id))时显示一些错误;

错误

Uncaught SyntaxError: Failed to execute 'querySelector' on 'Document': '#22' is not a valid selector.

我已经将keycloak与角度应用程序集成在一起.基本上,前端和后端都在不同的服务器上.Backend应用程序在apache tomcat 8上运行.前端应用程序正在JBoss欢迎内容文件夹上运行.

Angular配置

angular.element(document).ready(function ($http) {
    var keycloakAuth = new Keycloak('keycloak.json');
    auth.loggedIn = false;
    keycloakAuth.init({ onLoad: 'login-required' }).success(function () {
        keycloakAuth.loadUserInfo().success(function (userInfo) {
            console.log(userInfo);  
        });
        auth.loggedIn = true;
        auth.authz = keycloakAuth;
        auth.logoutUrl = keycloakAuth.authServerUrl + "/realms/app1/protocol/openid-connect/logout?redirect_uri=http://35.154.214.8/hrms-keycloak/index.html";
        module.factory('Auth', function() {
            return auth;
        });
        angular.bootstrap(document, ["themesApp"]);
    }).error(function () {
            window.location.reload();
        });

});
module.factory('authInterceptor', function($q, Auth) {
    return {
        request: function (config) {
            var deferred = $q.defer();
            if (Auth.authz.token) {
                Auth.authz.updateToken(5).success(function() {
                    config.headers = config.headers || {};
                    config.headers.Authorization = 'Bearer ' + …

我有一个弹簧启动启用rest api配置了keycloak.

keycloak.realm = demo
keycloak.realmKey = yfdsfdiufuydhf
keycloak.auth-server-url = http://localhost:8080/auth
keycloak.ssl-required = external
keycloak.resource = lib-backend
keycloak.bearer-only = true
keycloak.credentials.secret = a9fa2e60-324b-4508-b33d-84be2a981da3
# Keycloak Enable CORS
keycloak.cors = true

keycloak.securityConstraints[0].securityCollections[0].name = spring secured api
keycloak.securityConstraints[0].securityCollections[0].authRoles[0] = lib_sadmin

上面的代码将api返回给客户端而没有任何问题.但是当我删除领域角色并启用客户端角色时会给出403禁止错误.

您好我想重写默认thymeleaf配置到Web应用程序的自定义文件夹.Thymeleaf依赖项被添加到pom.xml文件中.我想映射到WEB-INF/views/文件夹.

我目前的配置

@Bean
public ThymeleafViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();
    thymeleafViewResolver.setTemplateEngine(templateEngine());
    thymeleafViewResolver.setOrder(1);
    return thymeleafViewResolver;
}

@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver());
    templateEngine.addDialect(new LayoutDialect());
    return templateEngine;
}

@Bean
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setPrefix("/WEB-INF/views/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setOrder(1);
    templateResolver.setCacheable(false);
    return templateResolver;
}

当我运行应用程序时,它显示以下异常.

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.thymeleaf.ThymeleafAutoConfiguration$DefaultTemplateResolverConfiguration': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Cannot find template location: …

我想从我的旧 Spring Boot 安全应用程序迁移到 keycloak。下面是我的安全配置。

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{
    @Autowired
    private CustomUserDetailsService customUserDetailsService;
     @Override
        protected void configure(HttpSecurity http) throws Exception {
         http.csrf().disable();

         http
         .authorizeRequests()
             .antMatchers("/*", "/static/**", "/css/**", "/js/**", "/images/**").permitAll()
             .antMatchers("/school-admin/*").hasAuthority("SCHOOL_ADMIN").anyRequest().fullyAuthenticated()
             .antMatchers("/teacher/*").hasAuthority("TEACHER").anyRequest().fullyAuthenticated()
             .anyRequest().authenticated().and()

         .formLogin()
             .loginPage("/login.html").defaultSuccessUrl("/loginSuccess.html")
            .failureUrl("/login.html?error").permitAll().and()

         .logout()
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout.html")).logoutSuccessUrl("/login.html?logout");

     }

     @Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
         auth.userDetailsService(customUserDetailsService).passwordEncoder(new BCryptPasswordEncoder());
        }
}

我已经安装了 keycloak 并且它在端口 8080 上运行。我发现问题是，我们应该在 keycloak 管理页面上创建角色和用户，但是我当前的系统是，用户和角色都在我的 MySQL 数据库上。我不想在 keycloak 上插入用户和角色以进行身份​​验证和授权。

我有一段使用 keycloak 和 JS 的代码。除了刷新令牌方法必须在令牌过期时从外部调用之外，代码工作正常。如何在过期时自动刷新令牌。

 var keycloak = Keycloak('keycloak.json');

 keycloak.init({ onLoad: 'login-required' })
        .success(reloadData)
        .error(function(errorData) {
            document.getElementById('customers').innerHTML = '<b>Failed to load data. Error: ' + JSON.stringify(errorData) + '</b>';
    });

 var loadData = function () {
        document.getElementById('subject').innerHTML = keycloak.subject;
        if (keycloak.idToken) {
            document.getElementById('profileType').innerHTML = 'IDToken';
            document.getElementById('username').innerHTML = keycloak.idTokenParsed.preferred_username;
            document.getElementById('email').innerHTML = keycloak.idTokenParsed.email;
            document.getElementById('name').innerHTML = keycloak.idTokenParsed.name;
            document.getElementById('givenName').innerHTML = keycloak.idTokenParsed.given_name;
            document.getElementById('familyName').innerHTML = keycloak.idTokenParsed.family_name;
        } else {
            keycloak.loadUserProfile(function() {
                document.getElementById('profileType').innerHTML = 'Account Service';
                document.getElementById('username').innerHTML = keycloak.profile.username;
                document.getElementById('email').innerHTML = keycloak.profile.email;

嗨，我想使用spring mvc ajax调用下载XLX文件。以下是我对服务器的ajax调用。

 $.ajax({
    type : 'GET',
    url : 'downloadExcel',
    beforeSend : function() {
        startPreloader();
    },
     complete: function(){
         stopPreloader();
     },
    success : function(response){
        console.log(response);
            var blob = new Blob([response], { type: 'application/vnd.ms-excel' });
            var downloadUrl = URL.createObjectURL(blob);
            var a = document.createElement("a");
            a.href = downloadUrl;
            a.download = "downloadFile.xlsx";
            document.body.appendChild(a);
            a.click();
    }
});

这是我的服务器代码

@RequestMapping(value = "/downloadExcel", method = RequestMethod.GET)
    @ResponseBody
    public List<LicenceType> downloadExcel() {
        return licenceTypeService.findAllLicenceType();
    }

我的代码实际上下载了excel文件，但是在excel表格上它显示为 [Object][Object]

zxing` lib 用于在我的 spring mvc 应用程序中生成二维码。他们很好地生成代码，现在我想要在 qr 图像底部的自定义文本。例如 - -

我使用的图书馆。

            <artifactId>javase</artifactId>
            <version>2.2</version>
        </dependency>

我使用的代码

 String charset = "UTF-8"; // or "ISO-8859-1"
                                Map hintMap = new HashMap();
                                hintMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);
                                createQRCode(code,
                                        dirPath ,
                                        charset, hintMap, 200, 200);
public static void createQRCode(String qrCodeData, String filePath, String charset, Map hintMap, int qrCodeheight,
            int qrCodewidth) throws WriterException, IOException {
        BitMatrix matrix = new MultiFormatWriter().encode(new String(qrCodeData.getBytes(charset), charset),
                BarcodeFormat.QR_CODE, qrCodewidth, qrCodeheight, hintMap);
        MatrixToImageWriter.writeToFile(matrix, filePath.substring(filePath.lastIndexOf('.') + 1), new File(filePath));
    }
