### 一、创建maven工程spring-boot-mvc，pom.xml文件依赖如下： ###

<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>2.1.4.RELEASE</version>
 </parent>
 
 <dependencies>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-thymeleaf</artifactId>
 </dependency>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-devtools</artifactId>
 <optional>true</optional>
 </dependency>
 </dependencies>
 
 <properties>
 <java.version>1.8</java.version>
 </properties>
 
 
 <build>
 <plugins>
 <plugin>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-maven-plugin</artifactId>
 </plugin>
 </plugins>
 </build>

### 二、在资源目录src/main/resources下分别新建文件夹static、templates，再分别在static文件夹下创建文件index.html，在templates文件夹下创建文件greeting.html ###

<!DOCTYPE HTML>
 <html>
 <head>
 <title>Getting Started: Serving Web Content</title>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
 </head>
 <body>
 Get your greeting <a href="/greeting">here</a>
 Get your greeting <a href="/greeting?name=User">User</a>
 </body>
 </html>

<!DOCTYPE HTML>
 <html xmlns:th="http://www.thymeleaf.org">
 <head>
 <title>Getting Started: Serving Web Content</title>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
 </head>
 <body>
 
 </body>
 </html>

### 三、创建控制器类GreetingController.java ###

package com.szcatic.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    
    @Controller
    public class GreetingController {
    
        @GetMapping("/greeting")
        public String greeting(@RequestParam(name="name", required=false, defaultValue="World") String name, Model model) {
            model.addAttribute("name", name);
            return "greeting";
        }
    
    }

### 四、创建引导类Application.java ###

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

### 五、启动引导类，运行程序 ###

### 六、打开浏览器，输入请求链接[http://localhost:8080/][http_localhost_8080] ###

### 七、分别点击here与User链接 ###

**从以上结果看出/greeting请求成功 **

### 八、项目目录结构如下： ###
