1.配置maven文件pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.hdwang</groupId>
<artifactId>spring-boot-test</artifactId>
<version>1.0-SNAPSHOT</version>
<name>spring-boot-test</name>
<description>project for test Spring Boot</description>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
</properties>
<!-- Inherit defaults from Spring Boot -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
<relativePath/>
</parent>
<dependencies>
<!-- Add typical dependencies for a web application -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<!-- auto redeploy -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
<!-- Package as an executable jar -->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>2.文件结构（static/templates/application.properties/logback.xml的名称都是约定好了的，只可以使用某几个名称，具体参考spring boot官方文档，下面的名称是其中一种配置方式）
3.建立启动类（放在顶层，子层（下级文件夹）的类方可被扫描注入）
@SpringBootApplication
public class Application {
/**
* main function
* @param args params
*/
public static void main(String[] args){
SpringApplication.run(Application.class,args);
}
}4.建立controller（在Application类的下级目录中）
@Controller
@RequestMapping("/common")public class Common {
@Value("${msg:Welcome!}")private String msg;/** * get a page
* @return a page with name called return value */@RequestMapping("login")public String getLoginPage(ModelMap map){
map.put("welcomeMsg",this.msg);return "login";
}
}5.建立网页模板login.ftl(freemarker必须使用ftl后缀，被这个坑了好久！js/css啥的都放在相应文件夹下，注意访问路径中不带/static,也被这个坑了好久！)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>login</title>
<link href="/css/home.css?1.1.11" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="/js/jquery-2.0.3.min.js?1.1.11"></script>
<script type="text/javascript" src="/js/home.js?1.1.11"></script>
</head>
<body>
<h1>login page</h1>
<h2>${welcomeMsg}</h2>
<form>
<div>
<label>用户名:<input type="text" id="username"/></label>
</div>
<div>
<label>密码:<input type="password"/></label>
</div>
<div>
<input type="submit" value="提交"/>
<input type="reset" value="重置" />
</div>
</form>
</body>
</html>
6.应用配置文件编写
新建application.properties文件并添加以下内容
msg=Ladies and gentleman,Welcome!
7.启动运行
浏览器中访问：http://localhost:8080/common/login
8.部署
mvn package 打个包
java -jar xxx.jar 运行这个包即可
