Thymeleaf 3.0 Spring Boot + Security integration does not work

Question

I struggle to get Thymeleaf to work with Spring Security in my Spring Boot 1.4.3 based project.

Tags like e.g.

        
                      

              相关标签:
       
      

Answer 1

I used to have the same problem. Thymeleaf SpringSecurity only works with versions 3.x.x of thymeleaf, and the version that's shipped with Spring-boot is something like 2.x.x atm.

Looking up how to add v3.x.x to my project brought me to the following documentation page: http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-use-thymeleaf-3

So you just need to add your dependencies, and then add the following in your properties to override the default version of thymeleaf to your dependencies:

<thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.1.1</thymeleaf-layout-dialect.version>

Answer 2

To get it working, if you are using Thymeleaf 3.0.2 with Spring Boot 1.4, you need to force version 3.0.1.RELEASE of thymeleaf-extras-springsecurity4 (because it inherits version 2.1.2 which does not work in combination with Thymeleaf 3):

<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity4</artifactId>
    <version>3.0.1.RELEASE</version>
</dependency>

The tags should be using the hasRole function.

<div sec:authorize="hasRole('ROLE_ADMIN')">

Answer 3

If you use Spring Boot 2.0.0.RELEASE:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

you need just the following dependencies:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity4</artifactId>
</dependency>

Version of thymeleaf-extras-springsecurity4 will be inherited from the spring-boot-starter-parent and would be 3.0.2.RELEASE.

Thanks to @yglodt for pointing this out.

Also in your templates add spring-security namespace xmlns:sec="http://www.thymeleaf.org/extras/spring-security" and use hasRole instead of hasAuthority value in <sec:authorize> tag:

<div sec:authorize="hasRole('ROLE_ADMIN')">
    ...
</div>
