这篇文章主要介绍了Spring Boot入门(web+freemarker)的相关资料,需要的朋友可以参考下

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="external nofollow" 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
