Spring Boot 和 Thymeleaf 3.0.0.RELEASE 集成

Question

当我尝试集成 Spring Boot 1.3.5.RELEASE 和 Thymeleaf 3.0.0.Release 时，我遇到了一个问题。我知道 Spring Boot 现在支持 Thymeleaf 3 版本，所以我尝试像这样解决这个问题：

@SpringBootApplication(exclude={org.springframework.boot.autoconfigure.thymeleaf.ThymeleafAutoConfiguration.class})

并添加我自己的 SpringWebConfig 配置。 不幸收到这样的错误：

java.lang.ClassNotFoundException: org.thymeleaf.resourceresolver.IResourceResolver
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_66]
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_66]

wrapped by: java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.transaction.TransactionAutoConfiguration due to org/thymeleaf/resourceresolver/IResourceResolver not found. M                                                                                                        ake sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

Answer 1

这要简单得多，只需阅读以下内容： http://docs.spring.io/spring-boot/docs/1.5.x/reference/htmlsingle/#howto-use-thymeleaf-3

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

Answer 2

弹簧靴 1.4.0 + thymeleaf 3.0.1

    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf</artifactId>
        <version>3.0.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf-spring4</artifactId>
        <version>3.0.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>nz.net.ultraq.thymeleaf</groupId>
        <artifactId>thymeleaf-layout-dialect</artifactId>
        <version>2.0.3</version>
    </dependency>

Answer 3

如 1.4.7.RELEASE 文档中所述： https://docs.spring.io/spring-boot/docs/1.4.7.RELEASE/reference/htmlsingle/#howto-use-thymeleaf-3

---

如果您使用 Gradle，请将其放入 build.gradle 文件中：

Gradle：build.gradle

ext['thymeleaf.version'] = '3.0.2.RELEASE'
ext['thymeleaf-layout-dialect.version'] = '2.1.1'

---

如果您使用 Maven，请将其放入 pom.xml 文件中：

Maven：pom.xml

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

---

（由于我没有足够的声誉，我发布了一个答案，而不是对以前的答案之一的评论。尤其是 build.gradle 部分。）

Answer 4

对于 Maven 项目，只需在 pom.xml 中添加以下行

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

为 gradle 项目创建一个 gradle.properties 文件，内容如下

thymeleaf.version=3.0.2.RELEASE
thymeleaf-layout-dialect.version=2.1.1

Answer 5

我有 Spring Boot 1.3.3 使用这个配置类与 Thymeleaf 3 一起工作。我记得必须努力解决同样的异常。此外，ThymeleafAutoConfiguration 不包括在我的自动扫描设置中，就像在你的设置中一样。

@Configuration
@EnableConfigurationProperties(ThymeleafProperties.class)
@ConditionalOnClass(SpringTemplateEngine.class)
@AutoConfigureAfter(WebMvcAutoConfiguration.class)

public class ThymeleafConfiguration extends WebMvcConfigurerAdapter implements ApplicationContextAware {

    private ApplicationContext applicationContext;

    @Autowired
    ThymeleafProperties properties;

    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;
    }

    private TemplateEngine templateEngine() {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.addTemplateResolver(urlTemplateResolver());
        engine.addTemplateResolver(templateResolver());
        // pre-initialize the template engine by getting the configuration.  It's a side-effect.
        engine.getConfiguration();
        return engine;
    }

    private ITemplateResolver templateResolver() {
        SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
        resolver.setApplicationContext(applicationContext);
        resolver.setPrefix("classpath:templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode(TemplateMode.HTML);
        resolver.setCacheable(properties.isCache());
        return resolver;
    }

    private UrlTemplateResolver urlTemplateResolver() {
        return new UrlTemplateResolver();
    }

}

（resolver.setPrefix、resolver.setSuffix 和 resolver.setTemplateMode 可能不再需要，但它们在第一个 beta 版本中。）

一步一步做简单的事

1.为百里香添加依赖。

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

2。添加对百里香方言的依赖。

    <dependency>
        <groupId>nz.net.ultraq.thymeleaf</groupId>
        <artifactId>thymeleaf-layout-dialect</artifactId>
    </dependency>

3.百里香的 SpringBoot 自动配置

spring.thymeleaf.cache=false
spring.thymeleaf.check-template=true 
spring.thymeleaf.check-template-location=true
spring.thymeleaf.enabled=true 
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.prefix=/WEB-INF/html/
spring.thymeleaf.suffix=.html
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.mode=HTML
spring.thymeleaf.reactive.max-chunk-size=0
