SpringBoot -＞ 第一个thymeleaf

导包:

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.thymeleaf</groupId>
            <artifactId>thymeleaf-spring5</artifactId>
        </dependency>
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-java8time</artifactId>
        </dependency>

1.主页index:主页是那个

主页只能是这些路径下面名字为index的html

		private static final String[] CLASSPATH_RESOURCE_LOCATIONS = { "classpath:/META-INF/resources/",
				"classpath:/resources/", "classpath:/static/", "classpath:/public/" };

		private Resource getIndexHtml(String location) {
			return this.resourceLoader.getResource(location + "index.html");
		}

2.写controller

@Controller
public class HelloController {
  @RequestMapping("/hello")
  public String hello() {
    return "hello";
  }
}

3.跳转页面:hello.html:怎么跳转,以前是视图解析器解析

以前是视图解析器在xml文件中配置,现在应该也在一个配置文件中,找thymeleaf的自动配置类

@Configuration(proxyBeanMethods = false)
@EnableConfigurationProperties(ThymeleafProperties.class)
@ConditionalOnClass({ TemplateMode.class, SpringTemplateEngine.class })
@AutoConfigureAfter({ WebMvcAutoConfiguration.class, WebFluxAutoConfiguration.class })
public class ThymeleafAutoConfiguration {

1.前缀是"classpath:/templates/";
2.后缀是".html";
3.然后知道了,跳转的页面在templates下的html

@ConfigurationProperties(prefix = "spring.thymeleaf")
public class ThymeleafProperties {

	private static final Charset DEFAULT_ENCODING = StandardCharsets.UTF_8;

	public static final String DEFAULT_PREFIX = "classpath:/templates/";

	public static final String DEFAULT_SUFFIX = ".html";

	/**
	 * Whether to check that the template exists before rendering it.
	 */
	private boolean checkTemplate = true;

	/**
	 * Whether to check that the templates location exists.
	 */
	private boolean checkTemplateLocation = true;

结果
