如何使用 Thymeleaf 配置 SpringBoot 并使用 sec:authentication 标签 [英] How can I configure SpringBoot with Thymeleaf and use sec:authentication tag

问题描述

我的应用程序使用 spring-boot 1.2.5 + thymeleaf + spring security.

我需要在我的网站上显示用户名，经过一些研究后，我似乎应该使用如下代码:

 的name"属性的值认证对象应该出现在这里.

但是我没有让 Thymeleaf 解析那个标签.请我需要一些帮助:(

解决方案

您需要在您的项目中添加 Spring Security 3 集成模块.这些模块是相当于 Spring 安全标签库的 Thymeleaf 方言.这些是 thymeleaf 额外模块，不是 Thymeleaf 核心的一部分.

在您的模板引擎中只需添加集成模块方言.

...<属性名称="additionalDialects"><设置><bean class="org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect"/></set></属性>...</bean>

添加模块后，您可以使用以下代码:

 的name"属性的值身份验证对象应出现在此处.

Thymeleaf 等效模块可以在此处找到.另外，请参阅此 ThemeLeaf 的分步教程

更新:

如果您使用的是 Spring Boot，您只需要在 pom.xml 中添加依赖项或在您的项目中添加 jars.

Im using spring-boot 1.2.5 + thymeleaf + spring security for my application.

I need to display the username in my website, after doing some research seems that I should use code something like:

<div sec:authentication="name">The value of the "name" property of
        the authentication object should appear here.</div>

However I don't get Thymeleaf to parse that tag. Please I need some help :(

解决方案

You need to add Spring Security 3 integration module in your project. These module are Thymeleaf dialect equivalent to Spring security tag lib. These are thymeleaf extra modules and are not a part of the Thymeleaf core.

In your Template Engine Just add the integration module dialect.

<bean id="templateEngine" class="org.thymeleaf.spring3.SpringTemplateEngine">
 ...
  <property name="additionalDialects">
    <set>
      <bean class="org.thymeleaf.extras.springsecurity4.dialect.SpringSecurityDialect"/>
    </set>
  </property>
  ...
</bean>

After adding the modules, you can use your following code:

<div sec:authentication="name">The value of the "name" property of
    the authentication object should appear here.</div>

Thymeleaf equivalent modules can be found here. Also, refer this Step by Step tutorial of TheymeLeaf

UPDATE:

If you are using Spring Boot, You just need add the dependency in the pom.xml or add the jars in your project.
