这是一个Spring Boot Web应用示例，使用嵌入式Tomcat + Thymeleaf模板引擎，并将其作为可执行JAR文件。  
使用的相关技术：

*  Spring Boot 1.4.2.RELEASE
 *  Spring 4.3.4.RELEASE
 *  Thymeleaf 2.1.5.RELEASE
 *  Tomcat Embed 8.5.6
 *  Maven 3
 *  Java 8

**1. 项目目录**

--------------------

手动创建以下文件夹目录结构：

**2. 项目依赖**

--------------------

声明 `spring-boot-starter-thymeleaf`以获得开发Spring + Thymeleaf Web应用程序所需的任何程序类库。  
参考如下 `pom.xml` 文件 -

**3. Spring Boot**

--------------------

使用`@SpringBootApplication`进行注释。运行此类来启动Spring Boot Web应用程序。  
*SpringBootWebApplication.java*

package com.th;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    @SpringBootApplication
    public class SpringBootWebApplication{ 
    
        public static void main(String[] args) {
            SpringApplication.run(SpringBootWebApplication.class, args);
        }
    }

一个简单的Spring控制器类：*WelcomeController.java*代码如下-

package com.th;
    
    import java.util.Map;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class WelcomeController { 
    
        @Value("${welcome.message:test}")
        private String message = "Hello World";
    
        @RequestMapping("/")
        public String welcome(Map<String, Object> model) {
            model.put("message", this.message);
            return "welcom";
        }
    }

**4. Thymeleaf +资源+静态文件**

--------------------

对于`Thymeleaf`模板文件，放入 `src/main/resources/templates/` 目录下, `src/main/resources/templates/welcome.html` 文件代码如下 -

<!DOCTYPE HTML>
    <html xmlns:th="http://www.thymeleaf.org">
    <head>
    <title>Spring Boot Thymeleaf Hello World示例</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    
    <link rel="stylesheet" type="text/css" href="webjars/bootstrap/3.3.7/css/bootstrap.min.css" />
    
    <link rel="stylesheet" th:href="@{/css/main.css}" href="../../css/main.css" />
    
    </head>
    <body>
    
        <nav class="navbar navbar-inverse">
            <div class="container">
                <div class="navbar-header">
                    <a class="navbar-brand" href="#">Spring Boot</a>
                </div>
                <div id="navbar" class="collapse navbar-collapse">
                    <ul class="nav navbar-nav">
                        <li class="active"><a href="#">首页</a></li>
                        <li><a href="#about">关于</a></li>
                    </ul>
                </div>
            </div>
        </nav>
    
        <div class="container">
    
            <div class="starter-template">
                <h1>Spring Boot Web Thymeleaf示例</h1>
                <h2>
                    <span th:text="'Message: ' + ${message}"></span>
                </h2>
            </div>
    
        </div>
        
    
        <script type="text/javascript" src="webjars/bootstrap/3.3.7/js/bootstrap.min.js"></script>
    </body>
    </html>

对于静态文件，如CSS或Javascript，将它们放入 `/src/main/resources/static/` 目录， `/src/main/resources/static/css/main.css`文件代码如下 -

h1{ font-size: 20pt; }
    h2{ font-size: 16pt; }

对于属性文件，放入 `/src/main/resources/` 目录中，  
`/src/main/resources/application.properties` 文件中的代码内容如下 -

welcome.message: Hello, Spring Boot

> 注意：阅读此Spring Boot服务静态内容以了解资源映射。

**5. 运行演示**

--------------------

启动Spring Boot Web应用程序，使用Maven命令：mvn spring-boot:run，运行结果输出如下-

**6. 构建可执行JAR**

--------------------

打包项目以创建可执行的JAR文件。使用Maven命令：mvn clean package，
