SpringBoot——web开发引入Thymeleaf模板引擎

**1、引入Thymeleaf模板引擎**

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-thymeleaf</artifactId>
                <version>2.2.1.RELEASE</version>
            </dependency>

**2、配置属性**

其实可以直接使用，不用配置。但Spring Boot官方文档建议在开发时将缓存关闭，那就在application.properties文件中加入下面这行就行了：

spring.thymeleaf.cache=false

**3、Thymeleaf使用**

源文档

package org.springframework.boot.autoconfigure.thymeleaf;
    
    import java.nio.charset.Charset;
    import java.nio.charset.StandardCharsets;
    import java.util.List;
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.http.MediaType;
    import org.springframework.util.MimeType;
    import org.springframework.util.unit.DataSize;
    
    @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;
    
    	/**
    	 * Prefix that gets prepended to view names when building a URL.
    	 */
    	private String prefix = DEFAULT_PREFIX;
    
    	/**
    	 * Suffix that gets appended to view names when building a URL.
    	 */
    	private String suffix = DEFAULT_SUFFIX;
    
    	/**
    	 * Template mode to be applied to templates. See also Thymeleaf's TemplateMode enum.
    	 */
    	private String mode = "HTML";
    
    	/**
    	 * Template files encoding.
    	 */
    	private Charset encoding = DEFAULT_ENCODING;
    
    	/**
    	 * Whether to enable template caching.
    	 */
    	private boolean cache = true;
    	}
    
    }

只要把HTML页面放在classpath:/templates/，Thymeleaf就能自动渲染：

### 使用 ###

1、导入thymeleaf的名称空间（ <html lang="en" xmlns:th="http://www.thymeleaf.org"> ）

<!DOCTYPE html>
    <html lang="en" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
    <h1>Hello静态资源模板引擎配置成功</h1>
    </body>
    </html>

2、编写Controller类

package com.hern.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @program: springboot-web-study
     * @description: 测试环境配置
     * @author: 宋兆恒（2336909208@qq.com）
     * @create: 2019-11-30 16:02
     **/
    
    @Controller
    public class HelloController {
    
        @RequestMapping(value = "hello")
        public String hello(){
            return "hello";
        }
    }

3、在浏览器地址栏中输入localhost:8080/hello进行测试
