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("${msg:Welcome!}") private String msg; /** * get a page * @return a page with name called return value */ @RequestMapping("login") public String getLoginPage(ModelMap map){ map.put("welcomeMsg",this.msg); return "login"; } }
5.建立网页模板login.ftl(freemarker必须使用ftl后缀，被这个坑了好久！js/css啥的都放在相应文件夹下，注意访问路径中不带/static,也被这个坑了好久！)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>login</title>
<link href="/css/home.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="/js/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="/js/home.js"></script>
</head>
<body>
<h1>login page</h1>
<h2>${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
