我的 isAuthenticated() 方法有问题。似乎无论用户是否登录，它总是返回 false。此外，调用此方法后，html 代码末尾不会显示任何内容。在此示例中:
aaa
<div sec:authorize="isAuthenticated()">
This content is only shown to authenticated users.
</div>
bbb
ccc
仅显示aaa。
Logged user: <span sec:authentication="name">Bob</span>
Roles: <span sec:authentication="principal.authorities">[ROLE_USER, ROLE_ADMIN]</span>
^这段代码工作得很好，所以 sec: 应该不会有问题(我猜)
我的 Thymeleaf 配置类:
public class ThymeleafConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware {
private ApplicationContext applicationContext;
public void setApplicationContext(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
@Bean
public ViewResolver viewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
resolver.setCharacterEncoding("UTF-8");
return resolver;
}
@Bean
public TemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setEnableSpringELCompiler(true);
engine.setTemplateResolver(templateResolver());
engine.addDialect(new SpringSecurityDialect());
return engine;
}
private ITemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".html");
resolver.setTemplateMode(TemplateMode.HTML);
return resolver;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler(
"/css/**")
.addResourceLocations(
"classpath:/static/css/");
}
}
和 Maven 依赖项:
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring4</artifactId>
<version>3.0.9.RELEASE</version>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity4</artifactId>
<version>3.0.2.RELEASE</version>
</dependency>
什么可能导致此错误？
最佳答案
Change your file pom.xml, and add this these dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>
Now in your html file add:
<!DOCTYPE html>
<html lang="es" xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/extras/spring-security">
that is all 😉
<div sec:authorize="isAuthenticated()">
Text visible only to authenticated users.
</div>
关于java - Thymeleaf+Spring，isAuthenticated()/hasRole() 不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48138580/
