将 Spring-Boot 从 1.5.3.RELEASE 迁移到 2.2.2.RELEASE 后，Thymeleaf 停止工作。
pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
...
<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>
我关注了Thymeleaf 3 migration guide + 阅读 Spring-Boot release ，但没有成功...

任何帮助表示赞赏。谢谢
编辑:
@Marged，模型已设置:
@Configuration
public class MvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/index").setViewName("index");
...
}
}
上下文路径默认为 (/)
@SpringBootApplication(exclude = { MongoAutoConfiguration.class, MongoDataAutoConfiguration.class })
@EnableConfigurationProperties({ AppConfig.class })
@EnableScheduling
@EnableJpaRepositories
@EnableAutoConfiguration
@ComponentScan("foo.bar")
public class MainApplication {
public static void main(String[] args) {
SpringApplication.run(MainApplication.class, args);
}
}
最佳答案
您的问题似乎与 Thymeleaf Layout Dialect 有关(参见#4)。 Spring-Boot 1.5.3.RELEASE 开箱即用地支持它，但 2.2.2.RELEASE 不支持。这甚至在 dialect's documentation 中有说明。 :
The layout dialect is already included as part of the Thymeleaf starter pack in Spring Boot 1.x, but has been removed in Spring Boot 2, hence the additional config step for Spring Boot 2 users above.
按照上面链接中的安装步骤应该会有所帮助，即:
- 添加 Maven 依赖项:
<dependency>
<groupId>nz.net.ultraq.thymeleaf</groupId>
<artifactId>thymeleaf-layout-dialect</artifactId>
<version>2.4.1</version>
</dependency>
- 向您的配置添加额外的
@Bean:
@Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
关于java - 升级到 Spring Boot 2.2.2.RELEASE + Thymeleaf 3.0.11.RELEASE，thymeleaf/layout 停止工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59739258/
