value mls mar 使用 blog doctype web app span 啟動
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.文件結構（static/templates/application.properties/logback.xml的名稱都是約定好了的，只可以使用某幾個名稱，具體參考spring boot官方文檔，下面的名稱是其中一種配置方式）
3.建立啟動類（放在頂層，子層（下級文件夾）的類方可被掃描註入）
@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類的下級目錄中）
@Controller @RequestMapping("/common") public class Common { @Value("${msg:Welcome!}") private String msg; /** * get a page * @return a page with name called return value */ @RequestMapping("login") public String getLoginPage(ModelMap map){ map.put("welcomeMsg",this.msg); return "login"; } }
5.建立網頁模板login.ftl(freemarker必須使用ftl後綴，被這個坑了好久！js/css啥的都放在相應文件夾下，註意訪問路徑中不帶/static,也被這個坑了好久！)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>login</title>
<link href="/css/home.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="/js/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="/js/home.js"></script>
</head>
<body>
<h1>login page</h1>
<h2>${welcomeMsg}</h2>
<form>
<div>
<label>用戶名:<input type="text" id="username"/></label>
</div>
<div>
<label>密碼:<input type="password"/></label>
</div>
<div>
<input type="submit" value="提交"/>
<input type="reset" value="重置" />
</div>
</form>
</body>
</html>
6.應用配置文件編寫
新建application.properties文件並添加以下內容
msg=Ladies and gentleman,Welcome!
7.啟動運行
瀏覽器中訪問：http://localhost:8080/common/login
8.部署
mvn package 打個包
java -jar xxx.jar 運行這個包即可
