你是使用配置文件配置entity的,把class那一串去了就行了

mapping resource="com/hibernate/Student.hbm.xml" class="com.hibernate.Student"/>你这样写肯定不行的,,如果你用的配置文件的话,,就这样
mapping resource="com/hibernate/Student.hbm.xml"/>,,如果你用的注解的话,,就这样 mapping class="com.hibernate.Student"/>

springboot 使用druid往后台传值SQL报错,是在是头疼不知道怎么办了,高C币,解决必采纳

userMapper; @Override public User selectByUsername(String username) { return userMapper.selectByUsername(username); } } ``` Realm注入时改成如下 ``` private static UserService userService; @Autowired public void setSecurityService(UserService userService) { this.userService = userService; } ``` 网上搜了一下 我也遇到了,在controller中使用@Autowire注入是OK的,偏偏在Realm中无法注入,原因是配置了shiroFilter过滤器,spring会首先执行过滤器,此时spring bean还没有加载进来,导致bean为空,不知道楼主解决了没有。 但是搜了一下Bean的生命周期,没有说shiro Bean 这一块Bean是怎么初始化的 可以具体看下 https://www.cnblogs.com/ASPNET2008/p/5507269.html

如何将Keycloak设置为humhub的身份验证提供程序

<div class="post-text" itemprop="text"> <p>I have a local apache2 server running humhub 1.3.14. My goal is to set Keycloak located on my rancher cluster as the authentication provider for humhub.</p> <p>After selecting "keycloak OpenId Connect" the user is successfully redirected to the keycloak server. After the user has authenticated, keycloak redirects back to my local humhub server. There humhub complains: "Unable to verify JWS: Unsecured connection" . to validate the JWS, humhub uses yii2-authclient/src/OpenIdConnect.php which requires "spomky-labs/jose:~5.0.6" (which is abandoned, but yii2 does still use it).</p> <p>in humhub/protected/vendor/yiisoft/yii2-authclient/src/OpenIdConnect.php setting</p> <pre><code>$validateJws = false </code></pre> <p>does nothing.</p> <p>humhub/protected/config/common.php:</p> <pre><code>return [ 'params' =&gt; [ 'enablePjax' =&gt; false ], 'components' =&gt; [ 'urlManager' =&gt; [ 'showScriptName' =&gt; false, 'enablePrettyUrl' =&gt; false, ], 'authClientCollection' =&gt; [ 'class' =&gt; 'yii\authclient\Collection', 'clients' =&gt; [ 'keycloak' =&gt; [ 'class' =&gt; 'yii\authclient\OpenIdConnect', 'issuerUrl' =&gt; 'https://xxxx/auth/realms/humhub', 'clientId' =&gt; 'humhub', 'clientSecret' =&gt; 'xxxxxxx', 'name' =&gt; 'keycloak', 'title' =&gt; 'Keycloak OpenID Connect', 'tokenUrl' =&gt; 'https://xxxx/auth/realms/humhub/protocol/openid-connect/token', 'authUrl' =&gt; 'https://xxxx/auth/realms/humhub/protocol/openid-connect/auth', 'validateAuthState' =&gt; 'false', 'validateJws' =&gt; 'false', ], ], ] ] </code></pre> <p>];</p> <p>Can anyone help?

I also downgraded spomky-labs/jose back to version 5.0.6, because of compatibility problems with the current humhub version 1.3.14.

将数据传递到嵌套模板不能按预期方式工作

<div class="post-text" itemprop="text"> <p>I was trying to get a struct passed to a nested template in Go, using <code>html/template</code> and tried to achieve it using both <code>template.ParseFiles</code> and <code>template.ParseGlob</code>, but it is not working as per my expectation because my understanding is not clear.</p> <p>My template code for the file <code>header.html</code> is </p> <pre><code>{{define "header"}} &lt;!DOCTYPE html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;link href="https://use.fontawesome.com/releases/v5.0.6/css/all.css" rel="stylesheet"&gt; &lt;meta charset="UTF-8"&gt; &lt;meta http-equiv="X-UA-Compatible" content="ie=edge"&gt; &lt;title&gt; SiteAdmin - {{.User}}&lt;/title&gt; &lt;/head&gt; {{end}} </code></pre> <p>and for the file <code>admin.html</code> is</p> <pre><code>{{template "header"}} &lt;body&gt; "User is {{.User}}" &lt;/body&gt; &lt;/html&gt; </code></pre> <p>I am using the <code>Execute</code> method on the type *Template as</p> <pre><code>type Admin struct { User string } data := new(Admin) data.User = "Guest" tpl, err := template.ParseGlob("views/templates/admin/*.html") CheckForErr(err) err = tpl.Execute(w, data) CheckForErr(err) </code></pre> <p>With the above code, I can pass around the struct data to <code>admin.html</code>, and it shows <code>User is Guest</code> in the browser. But if I try to pass it to any of the nested templates, it wouldn't. The title of the page still shows as <code>SiteAdmin -</code> and not <code>SiteAdmin - Guest</code>. The <code>User</code> data from the struct is visible only if I call it as <code>{{.User}}</code> inside the <code>admin.html</code> file, and any reference to it in the nested templates turns out to be not passed. Is this something achievable? </p> <p>Thank you all.</p> </div>
