這篇文章主要介紹了Spring Boot入門(web+freemarker)的相關(guān)資料,需要的朋友可以參考下

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.文件結(jié)構(gòu)（static/templates/application.properties/logback.xml的名稱都是約定好了的，只可以使用某幾個(gè)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(dòng)類（放在頂層，子層（下級文件夾）的類方可被掃描注入）

@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(wǎng)頁模板login.ftl(freemarker必須使用ftl后綴，被這個(gè)坑了好久！js/css啥的都放在相應(yīng)文件夾下，注意訪問路徑中不帶/static,也被這個(gè)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(yīng)用配置文件編寫

新建application.properties文件并添加以下內(nèi)容
