Thymeleaf 3 – Thymeleaf 3和Spring MVC快速入门

Thymeleaf 3发布到达。新版本带来了许多新功能，例如HTML5支持以及不带标记的文本模板支持– [# th:utext="${thymeleaf.version}" /] ，改进的内联功能– <p>Thymeleaf [[${thymeleaf.version}]] is great!</p> ，性能改进等等。

使用Thymeleaf 3和Spring MVC入门的最简单方法是使用Spring MVC 4 Quickstart Maven Archetype 。已更新原型以支持Thymeleaf3。下面将描述对原型所做的更改。

依存关系

该项目使用Spring Platform BOM进行依赖关系管理，但是（在撰写本文时）尚未声明对Thymeleaf 3的依赖关系，因此我需要手动声明版本。

胸腺

<dependency><groupId>org.thymeleaf</groupId><artifactId>thymeleaf</artifactId><version>3.0.0.RELEASE</version>
</dependency>

Thymeleaf Spring 4：

<dependency><groupId>org.thymeleaf</groupId><artifactId>thymeleaf-spring4</artifactId><version>3.0.0.RELEASE</version>
</dependency>

Thymeleaf Spring Security 4：

<dependency><groupId>org.thymeleaf.extras</groupId><artifactId>thymeleaf-extras-springsecurity4</artifactId><version>3.0.0.RELEASE</version>
</dependency>

使用原型生成的应用程序使用Java 8时间方言，并且由于Thymeleaf API已更改，因此方言依赖项也必须更新。在Maven Central中将其可用之前，我们必须将快照存储库添加到POM：

<repository><id>sonatype-nexus-snapshots</id><name>Sonatype Nexus Snapshots</name><url>https://oss.sonatype.org/content/repositories/snapshots</url><snapshots><enabled>true</enabled></snapshots>
</repository>

然后声明依赖项：

<dependency><groupId>org.thymeleaf.extras</groupId><artifactId>thymeleaf-extras-java8time</artifactId><version>3.0.0-SNAPSHOT</version>
</dependency>

配置变更

模板解析器

之前的模板解析器：

@Bean
public TemplateResolver templateResolver() {TemplateResolver resolver = new ServletContextTemplateResolver();resolver.setPrefix(VIEWS);resolver.setSuffix(".html");resolver.setTemplateMode("HTML5");resolver.setCacheable(false);return resolver;
}

之后的模板解析器：

@Bean
public ITemplateResolver templateResolver() {SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();resolver.setPrefix(VIEWS);resolver.setSuffix(".html");resolver.setTemplateMode(TemplateMode.HTML);resolver.setCacheable(false);return resolver;
}

模板引擎

@Bean
public SpringTemplateEngine templateEngine() {SpringTemplateEngine templateEngine = new SpringTemplateEngine();templateEngine.setTemplateResolver(templateResolver());templateEngine.addDialect(new SpringSecurityDialect());templateEngine.addDialect(new Java8TimeDialect());return templateEngine;
}

查看解析器：

@Bean
public ViewResolver viewResolver() {ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();thymeleafViewResolver.setTemplateEngine(templateEngine());thymeleafViewResolver.setCharacterEncoding("UTF-8");return thymeleafViewResolver;
}
